Simultaneously pressing the gas and brake. What happens if you take Viagra and diphenhydramine at the same time? Manual Transmission

We continue to publish articles from the “What happens if...” series. Today we will discuss what happens if you press both the gas and the brake at the same time.

When you simultaneously press the gas pedal and the brake pedal, the following happens: the engine speed increases, more torque is transmitted to the wheels, and at the same time the brakes hold the wheels, preventing rotation, or even preventing them from turning.

In this case, the maximum load falls on the elements transmitting torque.

The question arises: what consequences will there be for the car, and why do this at all?

We will not go deeply into the design features of gearboxes - we discussed this in more detail in the material “”, but it is quite obvious that for different types of gearboxes the consequences will be different.

On a manual transmission

On a car with a manual transmission, the clutch is responsible for transmitting torque from the engine to the gearbox, which mechanically connects the elements of the engine and manual transmission.

The clutch operates based on the frictional force between two discs, one of which is fixed to the engine shaft, the other to the gearbox shaft.

When the clutch is depressed, the engine is disconnected from the gearbox. When the clutch pedal is released, due to the increasing friction force between the clutch discs, the speed of rotation of the gearbox shaft will tend to equalize the speed of rotation of the engine shaft.

When the pedal is released, the rotation speed of both shafts is the same.

• As engine speed increases, the engine shaft transmits more torque to the manual transmission shaft.
• A difference in the rotation of the clutch discs occurs and increases - slippage.
• A large amount of heat is generated.

In other words: when you simultaneously press (and hold) the gas and brake pedals on a car with a manual transmission, the clutch will fail (burn out) first. The rest of the transmission elements and the engine will also be overloaded.

The good news is that there is a high chance that the engine will stall before the clutch has burned out.

On automatic transmission

In a car with an automatic transmission, a torque converter is responsible for transmitting torque from the engine to the gearbox, which connects the elements using fluid.

The design of a torque converter can be divided into three parts: pump, turbine and reactor.

The pump wheel is rigidly connected to the torque converter housing, and when the engine shaft rotates, it creates an oil flow inside the torque converter, which rotates a turbine rigidly connected to the automatic transmission.

The reactor serves to correct oil flows: with its help, the torque when starting the car increases, and the engine does not stall when stopping with the gear engaged.

So, when you press the gas and brake at the same time, the following happens:

• As engine speed increases, the pump wheel transmits more torque to the turbine wheel connected to the automatic transmission.
• A difference in the rotation of both wheels arises and increases.
• As a result, the turbine wheel “slips” in relation to the pump wheel, releasing a large amount of heat.

In other words: when you simultaneously press (and hold) the gas and brake pedals on a car with an automatic transmission, the torque converter will be the first to fail (burn out). Naturally, the remaining elements of the transmission will also be subject to excessive loads.

On the other hand, the automatic systems of many modern cars can protect the car from such abuse: when the brake is fully depressed, the automatic transmission is blocked.

Why press the gas and brake at the same time?

Despite the serious consequences for the car, pressing both pedals at the same time is used! But they are not used often and for the purpose.

This technique is used on manual transmissions:

• to redistribute weight between the axles of the car when driving over uneven surfaces;
• to maintain the required engine speed during braking;
• to trigger a controlled drift.

It is not difficult to guess that such techniques are available only to athletes, and it is advisable to use them on specially prepared cars.

And if available Automatic transmission: press both pedals at once for testing general characteristics of the engine and gearbox.
To do this, the brake is depressed, the engine is started, the automatic transmission is switched to “drive” mode, and the accelerator is depressed. Based on the achieved engine speed, diagnostics are carried out.

So

If you hold down the gas and brake pedals at the same time, the clutch or torque converter will burn out. Other transmission components may also be damaged.

Simultaneous dosed pressing is used in sports and in car diagnostics.

In order to learn to use all the capabilities of a car, long and persistent practice is required. Therefore, without special training, do not press the gas and brake at the same time.

Carriage disputes are the last thing when there is nothing left to drink! And the train is moving, and the compartment is empty, and he wants to talk!....
Once in 2010, I had a chance to go from Moscow with friends through Kyiv to Bukhavel to ski. Friends and two days of entertainment were waiting for us in Kyiv. My friend and I entered a compartment where two women in their late fifties were already seated. One typical little Ukrainian is a cheerful woman who had a saying for everything and a woman who looked like a teacher. Our only belongings are two backpacks with things and a bag of drinks and food, the cheerful little Ukrainian has about five trunks with clothes, the teacher only has a suitcase on wheels. The woman was still lamenting and worried that two hundred hryvnia would not be enough to pay off the customs officers for the trunks, to which the teacher told her not to worry about anything and that she would sort out all the issues with customs. We gave them our lower bunks and, throwing our backpacks, went into the restaurant car to eat and play cards. When we returned after dark, the women were sitting and talking about something in low voices, the teacher was listening to a story about a woman’s son, who, against his mother’s will, married a woman three years older than himself and with two children, giving birth to a third. Due to conflicts with their mother, they moved to a rented apartment, and they refuse to help their mother, although she has some kind of clothes shop in Shulyavka and helps her second son little by little. She could not believe that they were in love, as her son told her, and he would come to his senses and marry the daughter of her friend, whom she had been trying to marry him since childhood. She did everything she could to open his eyes to her shortcomings, but her son simply closed in on himself until they moved into a rented apartment. And she firmly believed that she wished him only the best, but he didn’t listen to his mother! I listened to this whole story with half an ear and the teacher silently, without interrupting, with some kind of sad smile!) When the monologue was interrupted, she asked the woman if she really thought that she was doing well for her son? She answered in the affirmative! Then she started telling...
She turned out to be a civil judge from Kharkov and literally a couple of years before she had a case pending. One young married couple applied to determine the paternity of their daughter. The three of them came to the first meeting, their two-year-old daughter, the spitting image of her father’s appearance, wheat-colored hair and the same protruding ears! Moreover, the child’s mother insisted on the examination! The judge looked at her daughter with a smile and said that maybe it’s not worth spending money on a genetic examination, but that it would be cheaper to look in the mirror?)) But they didn’t appreciate the joke and insisted on their own! When her husband left and she remained to sign something, the judge asked why she needed it? And she told the story...
They lived in the same house, but did not have time to get married before the army, since his mother was against it, and he ended up serving in a unit in the same city. He went AWOL several times, and by the time of his demobilization, she had safely given birth to a girl. He began to live with her, but the mother kept telling her son that she was a slut and he was a cuckold and raising someone else’s daughter! Even the fact that she has a complete portrait resemblance to her father did not convince his mother. And one day he went to take out the trash and did not return home to his wife but went to his mother! And to prove she was right, she ordered a paternity test. When the examination arrived, they came for the result and waited in the corridor, sitting on a bench and holding each other’s hands without stopping kissing! She said that she could not invite them for about thirty minutes, since the result gave an absolute guarantee that he was not the father of his daughter!!! I just couldn’t find a phrase to start a conversation. She cannot lie to save her family, and she must tell the truth! Then it was as if something had pushed her and she realized what needed to be said, although she was not sure of the result. They came to pick up the conclusion, holding hands and smiling, and the husband said that he already regretted that he paid money for a whim and lost time. And then she tells them that they are young and have their whole lives ahead of them and the main thing is that they love each other, so they must correctly understand everything she says! After reading the examination report, she realized that nothing could hold them together. He silently looked at his wife with contempt, she was trying to prove that there was a mistake and this could not be! But the examination is not wrong! The guy took off the ring, put it on the table with the keys to the apartment and a photograph of his daughter and silently left without saying goodbye! She repeated one phrase about the fact that this was a mistake and she would prove she was right! But there was no one left to prove it to! ... Tears glistened in the woman’s eyes, and the little Ukrainian also wiped her eyes with a handkerchief. They silently looked out the window for several minutes, then the laughing girl said that she was grateful to fate for her fellow traveler, who cured her of stupid maternal jealousy and excessive care and guardianship....
I apologize for the many letters, incorrectly placed commas and spelling errors!!))))
Yes, when the customs officers came in, she took out the bag and said that these were her things, they saluted and silently left, and even the border guards briefly looked at our passports and didn’t ask any questions!)))

she silently told the women to the daughter mother to son

Some relationships, once started, stay with you for life. AND
this is the best thing that can happen to a relationship between a man and a woman.
Moreover, none of them may even set the task of preserving them. But
there is a certain affinity of souls and understanding of life that does not allow
break the thread. The tangle of destinies unwinds, and this thread stretches through
decades, tying you together.

Valentina had a gorgeous figure. Knowing this very well, she wore
only tight outfits. The men stopped on the street and saw him off
Valentina floating along the sidewalk with greedy glances. Her curves were tight.
I wanted to free her from her clothes, undress her immediately, let her lush
the body can breathe freely. This chest needs to rise in waves. And the hips
supposed to tremble under rough male palms. She studied the same
Faculty, same as me, a year older. And I always felt a shudder,
when we met in the university corridors. She gave me gifts
a benevolent smile. And I hid my gaze because it was too obvious
It was that even with my gaze I wanted to caress her.

One day I couldn't stand it. Came up. And he stated directly:

How about a date?

Unexpectedly, - she smiled again, but in a different way, it happens
the graceful cat smiles, showing sharp teeth. - I don't mind.

Maybe on Friday?

Let's. I have a lecture. But so be it, I can walk her. Just for the sake of
you.

You never know what a relationship will turn into. Honestly, I
Then only the bed was visible. I was going to play with her to my heart's content,
and then return to Dasha. But on Friday, walking in the park, we
We started talking, and suddenly it turned out that we had a lot of common topics. She, like
I was interested in literature and history. She had excellent erudition -
thanks to educated parents. Plus we had the same feeling
humor, and we immediately began to make fun of each other without malice - and
laugh.

I walked her home, I couldn’t part with her for a long time, I liked her
communicate with her, and when he finally left, he kept thinking: how amazing - yet
this morning Valka was a curvy, inaccessible beauty, and now
turned into a living person, sociable, like a board. Here
only my passion mysteriously dissolved. Maybe because
A man needs a mystery to be attracted to a woman. Valentina
for me it was no longer a mystery - an open book, on the same page as
and I. Moderately cynical, moderately businesslike, knowing her own worth, with excellent
sense of humor. Romance with such a girl, I realized, is simply impossible.
Tell her you love her. And she will laugh in response.

We called each other. And on Sunday she came to visit me.

Maybe we can have sex? – Valya suggested in response to my proposal
"have some tea."

“Come on,” I agreed after a short pause.

While I was undressing her, we had a lot of fun with each other. Us
it seemed like it was all some kind of circus. Her body was truly gorgeous.
Nothing extra. And everything was created with such high quality by the Lord God that
It’s immediately clear who the real Creator is. I caressed her for a while. After
I decided to run my hand over my stomach. And she giggled:

What are you doing, ticklish?

Probably, on the other hand, I would have felt wounded. But it was Valyukha
- insider. I laughed too, and began to tickle her much more actively...

Crap! - I said after a while, when she was lying under me, and
I, propped up in my arms, looked between her large breasts at my barely
erect member. - This is the first time this has happened to me.

Poor thing,” she laughed again. But she immediately covered her mouth with her hand.
She made a serious face. Although the eyes were amused. – It’s all my fault.
Lie down. Now.

I lay down on my back. And she began to caress my flaccid penis with her mouth. Her actions
had an effect - soon the member tensed up and came into combat readiness. I
He laid her on her back, entered her and began to move rhythmically. Constantly
thinking at the same time: “What nonsense, she’s a gorgeous girl, and her figure, and
face – an incredibly beautiful girl, maybe there’s something wrong with me? "And right there
my dick went limp again. And she had to make an effort again to get him
lift. This went on several times. Within an hour and a half. Bye
I finally didn't cum.

I pulled on my panties and sat down in the chair, looking at her expectantly. Because the
We amazingly understood each other without words, she said:

It was the worst sex of my life.

And then we felt so funny that we started laughing nonstop. AND
They couldn’t calm down. They say about such cases: “laugh in the mouth”
"I got it."

Of course, I couldn't be satisfied with "the worst sex of her life"
I needed to prove to Valya that I was a real male. And within
Over the next few weeks, I completely restored my shaky reputation.
After several successful times, she began to excite me more and more. Yes and
she was no longer laughing, but was reaching out towards her, her mouth parted and breathing hotly...

Then I met Valya’s parents. The family seemed to me
wonderful. Dad had his own flower business. But most importantly
Nikolai the Second was a hobby. He collected books about the latter
Russian Tsar, and seemed to know everything about him. Mom was a housewife. But
such an intelligent, beautiful and sweet woman that she resembled
a Russian housewife in a colorful robe and curlers, and a classic
American from the fifties - whose lawn near the house should
be well-groomed, and always look as if you are going to a social event in an hour.

Valya also had an old grandfather, a keen chess player. We spent with
he spends many hours playing chess. Basically, he won. But a couple of times I
managed to reduce the game to a draw.

There are many scoundrels living in this world. Grandfather once went to
grocery store for kefir. And he didn't return. At the entrance of his own house
brutally beaten by two drunken scum. He did not die immediately. I was admitted to the hospital with
broken skull. And there he soon fell into a coma and died. At trial
the killers behaved defiantly and brazenly. And they got it in full. me always
I wondered why people of this sort put on such a performance at
court? Don't they understand that by doing so they are digging a hole for themselves? For me they
behavior is inexplicable. How inexplicable the motivation for their actions is.

In general, Valya’s family was so strikingly different from Dashina’s that I
I was amazed at what an attitude could be. I'm not used to this. I was in
their home is both cozy and warm. And they understood me perfectly. And no
I didn’t experience any tension in communication. There was only one problem: I will give
loved, but not Valya.

You can convince young people for as long as you like that they need to think
head, and when choosing a companion, you need, first of all, to look at her
family. They will never listen to advice from experienced people
parents. Because for a young creature, feelings always come first.
Unless, of course, this is a real person, and not just a dreamer
material wealth, a moral monster raised by moral monsters -
parents. And yet, how scared for my daughters, how I want them to
met an equal, close in spiritual development and intellectual
human level. But love is evil. It may happen that you have to beat the goats and
to venture away from your own home...

Valya and I met and never parted again. But both a man and
did not become a woman for each other. Her parents never understood ours
relationships. It seemed to them that here they were, two halves of a single whole, it seemed
If only you could be found, grab each other and swim in the ocean of life. But we
We weren't meant to be a couple, we were meant to be friends. And they became
in the end.

Then I watched countless Valka novels, not at all
jealous. Only sometimes he criticized me for being dissolute. I used to scold when
she found a complete cretin - painting him as a grandiose macho. Feminine taste -
mystery. In the end, having gone through an extremely unsuccessful marriage with
an alcoholic who for some reason seemed similar to me (she
specially emphasized this point), Valya married an artist. U
they had a daughter.

And then Valka and her husband moved to the USA. And we got lost for a while
time. But only to meet again in New York. I remember
What a shock I felt when I saw her gorgeous figure. And curled necks
American men. One black guy even clicked his tongue.

“How similar to Valka,” I thought, and then: “Ekarny Babai, this is
she! »

And he ran, pushing through the crowd, down 42nd Street, shouting at the top of his lungs:

Valya! Valka, wait!

Even when I first came to the States, I thought that it would be nice to find
your old friend. After all, she lives somewhere in this country. But realizing
the scale of America, I understood that these were empty dreams. And so it was as if he pulled
her to Manhattan...

She was literally speechless. American men continued to stare, now
already with envy, when we hugged, and I kissed her almost passionately from
joy. But wait a minute - passionately, it happened by accident.

Where are you?! How are you?! Come on, tell me! - without ever letting her out
hugs, beaming, I asked.

Yes, right here, next to you... Step, let go, it’s uncomfortable...

And in the cafe on the corner she later told me how she lived all these years. What
it was hard at first. But now everything is fine, we bought a car first, then
house. True, now everything is in loans. In general, standard emigrant
story. And I told her about my misadventures...

It was as if we were deliberately following each other around the world. I'll follow her first
went to the USA. Then she follows me to Russia. This is what happens when fate
closely connected.

Her husband in the States first fell into depression. His painting is of no one
interested. His paintings did not sell. They didn't even take him
illustrator for freelance publications. Then he met someone
connoisseur. And he arranged a small exhibition for him in his own gallery.
There it was discovered by a local expert. They began to write about Valka’s husband in
newspapers. The paintings began to sell. It was during this period that we
met. Then he changed his writing style a little - and his canvases suddenly
have become very, very in demand. As fees grew, it became
the character of Valka’s husband deteriorates. Previously a quiet, modest man, he
turned into a domestic tyrant. He demanded to be treated as
genius. And it was a real shock for him when Valya one day
day she announced that she was leaving him. How?! From him?! From great talent?!
The fate of the wife of a genius, you know, is not suitable for everyone... Some prefer
an ordinary life, but calm... A tedious legal battle followed,
lasting several years. Finally, Valentina, having taken a quarter of all the money,
which the lawyers did not have time to pick up, and the daughter left for Russia. After
numerous courts and communication with lawyers, she suddenly disliked the States.
She said it was stuffy there.

By that time I had already lived in my homeland for a long time. We called each other regularly
corresponded. And that’s why I met her at the airport in Moscow.

She emerged from the glass doors of the Sheremetyevo 2 terminal in a chic
in a fur coat and sunglasses that fit half her face, she looks like a millionaire. With a blonde
daughter - a big thing, towering a head taller than her mother. Now a girl
makes a career as a model. With her legs and height, there is a direct path for her there.
It was early spring. The snow has already melted. And in Valka's fur coat there must have been
very hot. But she could not appear in her homeland otherwise. She needed
to show everyone, and first of all to herself, that she is not coming back,
and came to her homeland from overseas as a winner. I'm fine
understood.

When we turned onto Leningradskoye Shosse, I turned to the “millionaire” and
asked:

Valka, would you like a beer?

Beer? – she asked in surprise.

Well, yes. Our Russian beer.

I really want our Russian one,” she said and laughed, just like
just like once upon a time.

I pulled over at the tent and bought her a bottle of cold beer.

She took a long sip and closed her eyes like a cat:

I haven't drunk beer for a hundred years. Okay.

This is the Motherland, Val, welcome back,” I smiled. I was glad that she
arrived. I really missed her.

Every person has had toothache at least once in their life. Sometimes a tooth hurts so badly that it is simply impossible to endure this feeling for a long time.

It is in such a situation that even those people who try to avoid a visit to the doctor to the last minute go to the dental clinic.

What if it’s not just one tooth that hurts, but a whole row of teeth or part of the jaw? What to do in such a situation and what diseases can be a symptom of discomfort when it seems that all the teeth hurt at once?

So, the middle alveolar branch goes to the premolars, and the anterior branch goes to the incisors. All nerve endings in the upper jaw are united in the upper dental plexus. Gingival nerves also extend from it to the gums and walls of the dental alveoli. The lower jaw also has a similar innervation system.

Small nerve endings leading to the top of the tooth and gums are, in fact, processes of the trigeminal nerve. If in any area, be it a tooth, gums or the trigeminal nerve itself, any disturbance occurs along the innervation, then pain sensations will spread throughout the entire nerve fibers penetrating the jaw.

That is why, if several teeth are affected by pulpitis or caries, there is a feeling that the entire jaw hurts.

The pain spreads along the nerve fibers of the entire dentition and sometimes it is difficult to identify the tooth that caused the discomfort.

Features of the clinical picture

Toothache affecting the entire jaw can be very different: acute, aching. It may appear periodically (usually at night) and disappear again.

Aching pain most often appears when a person is sleeping, this is due to the fact that at rest the blood flow to the jaws increases; in addition, in the evening the adrenal glands are inactive and produce fewer steroid hormones.

In acute conditions, such as periodontitis or pulpitis, the pain is usually persistent and unbearable, sometimes throbbing. Very often, after eating hot or cold food, you get the feeling that all your teeth hurt at the same time. In this case, the unpleasant sensations pass quite quickly.

In any case, in order to find out the cause of the symptoms, you need to consult a doctor.

Causes of the pathological condition

There are several groups of causes and diseases that make it feel like all your teeth hurt at once. Some of them are of a dental nature, while others are not directly related to the teeth and gums, but at the same time there is a feeling that it is the teeth that hurt.

If all your teeth hurt at the same time, this may be caused by the following dental factors:

1. Exposure of dentin or cracks in tooth enamel, enamel hypersensitivity. When dentin is exposed or cracked, teeth hurt after eating cold, hot, spicy, sweet, or salty foods. Painful sensations may spontaneously appear and disappear. Dental reactions to hot and cold may occur after treatment of multiple caries.
2. Caries. The feeling that all the teeth on the left or right side of the jaw hurt can occur in a situation where several teeth are affected by caries at once.
3. Pulpitis. Each person reacts differently to toothache, so with this disease it may feel like your entire jaw is hurting. At the same time, the pain is inconsistent, twitching, it comes and goes. With pulpitis, the death of the pulp occurs, and an inflammatory process also occurs.
4. Periodontitis. It is characterized by the fact that the inflammatory process affects periodontal tissue, and pus can accumulate at the site of inflammation. With this disease, the entire jaw may hurt, and the pain can even radiate to the facial area.
5. With a root cyst Pain sensations also appear in the jaw area, which do not have a clear localization, it seems that the pain is happening all at once. Exacerbation of the disease may be accompanied by weakness and fever.
6. A slight aching pain, a feeling that the whole jaw hurts, can occur when pericoronitis. This disease is associated with improper eruption of wisdom teeth.
7. Gingivitis– inflammation of the part of the gums directly adjacent to the teeth. Painful sensations can be felt in all gums, while they turn red and bleed.
8. Periodontitis– the result of gingivitis not cured in time. At later stages of development, pain is localized in the area of ​​one or more teeth, which is associated with the formation of abscesses in the periodontal pocket.
9. Poorly treated caries when the filling is placed incorrectly or particles of infected tissue remain in the drilled cavity, it can also cause toothache.

Non-dental causes of tooth pain without clear localization include:

1. A common cold or hypothermia. Sometimes wet feet can lead to toothache. In such a situation, it is recommended to steam your feet and drink warm tea with honey.
2. Stress can also cause your entire jaw to feel like it hurts. The best treatment in such a situation is proper rest and sedatives.
3. Cluster headache may radiate to the jaw.
4. For angina pectoris pain may radiate to the left shoulder and lower left side of the jaw. In this case, you may experience a feeling that the teeth on the left side hurt. Such pain can be a harbinger of a heart attack.
5. Inflammation of the trigeminal nerve- the cause of toothache. In this case, the entire row of teeth aches on the right or left.
6. For sinusitis Usually all the upper teeth ache, this is due to the fact that the maxillary sinuses are located very close to the roots of the upper teeth.
7. Otitis media most often causes pain in the area of ​​the chewing teeth. This is a dangerous disease that can lead to meningitis and therefore requires immediate treatment.
8. Temporomandibular joint dysfunction leads not only to toothache that covers the entire jaw, but also to changes in muscle tone and other unpleasant symptoms.

In case of such a problem, you should...

If unpleasant symptoms occur, you should consult a doctor as soon as possible. It is important to remember that the sooner a diagnosis is made and treatment is prescribed, the faster the painful symptoms will go away.

Before going to the clinic, you can only slightly alleviate the suffering with home remedies. Painkillers that are available in every first aid kit will help relieve pain: Analgin, Tempalgin, Ketorol. If toothache is accompanied by fever and inflammation, you can take Paracetamol or Ibuprofen.

It is undesirable to warm up the area where unpleasant sensations are located.

If pain is caused by dental problems, then rinsing the mouth with a soda solution and a compress with fir oil can help. To prepare a compress, place 5 drops of oil on a piece of bandage and apply to the gum.

Also, instead of fir drops for a compress, you can use “Tooth drops”, “Denta” or a solution of novocaine.

A decoction of oak bark can also pacify toothache. When all your teeth hurt, pour boiling water over a tablespoon of oak bark and let it brew. You can rinse your mouth with the resulting decoction.

The feeling that the entire jaw hurts at once can occur with various pathologies. Pain in the teeth is a consequence of the disease, and not an independent disease.

If the first symptoms occur, do not delay going to the clinic. Only a competent doctor can deal with the problem and prescribe effective treatment.

Most often, damage to the nervous system humans are the result of infectious diseases. Diseases of this kind, in addition to causing complications dangerous to human health, contribute to the development of damaging factors in the nervous system.

For example, a patient with the flu may develop a hypertensive (hypotonic) crisis. There are obvious disturbances in the functioning of the body, both nervously and emotionally. More than others, people with injuries to the skull, those with a concussion, and those who regularly drink alcoholic beverages are susceptible to this.

Classification of the disease

The flu can cause a serious complication that will result in severe damage to the nervous system. The list is very extensive, the favorites are:

1. Meningitis - an inflammatory process that affects the soft membrane of the brain.

2. Encephalitis - brain tissue is inflamed.

3. Inflammatory processes affecting the arachnoid membrane of the brain are called arachnoiditis.

4. Otitis media and sinusitis can also be safely included in this list.

As a result, such a chain of inflammatory processes can lead to swelling of the brain tissue.

Symptoms of arachnoiditis, principles of treatment

The disease arachnoiditis becomes noticeable approximately on the seventh day after a person falls ill with the flu.

Internally, the patient feels an improvement in his health, but in fact, a more dangerous disease is hiding here. Arachnoiditis reaches its true strength, the peak of its capabilities, several months after the end of the infectious disease (flu).

The disease has its own classification, depending on the area of ​​manifestation of the lesion. It is characterized by the presence of acute pain in the head, mainly in the frontal part, the bridge of the nose. At the same time, severe dizziness occurs and gag reflexes are continuously repeated. During normal walking, the patient noticeably sways from side to side. There is a decrease in hearing - the ear canals become blocked. During an exacerbation, there is a possibility of seizures with convulsions.

A common symptom for all types is the presence of a severe headache that does not provide the body with the slightest opportunity to rest. On the contrary, it periodically intensifies as a result of increased physical and mental stress, the onset of cooling or overheating of the body above permissible norms. During severe pain, gag reflexes may occur.

The extreme danger of the disease lies in the fact that the cerebrospinal fluid ceases to circulate normally, which leads to inflammatory processes in the area of ​​the arachnoid mater. In the acute stage, doctors use antibiotics for therapy. For the chronic form of the disease, absorbable substances such as agave juice (aloe) and vitamins that produce a general strengthening effect (group B) are prescribed. During the onset of seizures, special drugs are used against convulsive muscle contractions.

If all treatments are carried out on time, then the chances of strengthening the foundations of human health that have been shaken by arachnoiditis increase significantly. Diagnosis of the disease at an early stage, qualified treatment of infectious diseases are the main preventive measures necessary for such a situation.

Signals of meningitis

In the case where the nasopharynx is the site of formation of intense inflammatory processes, situations of disruption of the normal functioning of the meninges are not uncommon. This fact indicates the approach of another dangerous type of influenza - meningitis.

For infection, the favorite method of transmission is airborne droplets, through mucus, saliva, coughing, and normal conversation. For some, the infectious disease manifests itself in the form of a runny nose, but no significant deviation in their health is observed, and there is no obvious need to seek medical help. It follows from this that often healthy-looking people are carriers of infectious diseases.

Children and people with reduced body resistance to various diseases, that is, those with low immunity, are especially at risk. The chances of being infected with meningitis viruses increase when consuming low-quality food and water. In order to significantly reduce the likelihood of infection, it is necessary to thoroughly boil water before using it.

At the same time, you need to pay due attention to strengthening your immunity: adhere to the key principles of hardening the body, take vitamins, and systematically engage in health-improving physical education.

Regular walks in the open air, combined, if possible, with breathing exercises, would be appropriate.

The symptoms of the initial days of the disease are characterized only by the appearance of elevated temperature and pain in the head area. After a certain period of time, muscles begin to ache, weakness, fatigue occur, and the sense of appetite is lost.

To these symptoms, a runny nose and a sore throat are gradually added. Over time, the effect of all symptoms intensifies. The patient often experiences nausea and vomiting, which do not bring relief. The feeling of irritation to all external factors increases, lethargy occurs, and insomnia occurs.

Further, events can develop more negatively: the urge to vomit intensifies, there is confusion in consciousness, delirium and convulsions occur. Reddish, purple smudges appear all over the body. The most “popular” places for their manifestation are the muscles of the buttocks, thighs, and legs. Much less frequently, the facial area joins this list. The danger of deterioration of health from independent, unqualified treatment for meningitis acquires double relevance. The timeliness of starting therapy is extremely important, because in this situation the clock is counting. If the moment is missed, and meningitis is already “lighting its stars” with might and main, then delay is unacceptable - an emergency call to the ambulance is the only right decision.

The most characteristic symptom of meningitis is sharp pain in the head when trying to bend the head forward towards the chest. There are two main types: serous and purulent. In the first case, in most cases, everything is limited to a slight inflammation of the brain. Of course, this statement is relative, since we are talking about the most important organ of the human body. Speaking about purulent inflammation, the situation looks much more threatening, since the meninges are the place where purulent masses accumulate. This circumstance is extremely dangerous and requires immediate treatment. The presence of a purulent form of meningitis is determined by the appearance of a rash on various parts of the body.

After determining the diagnosis, intensive treatment of the disease is carried out using drugs from the class of antibiotics. The use of drugs in this group not only provides patients with survival (a significant reduction in mortality), but also gives them the opportunity to hope for a full life after the rehabilitation period.

Recurrence of meningitis is extremely rare. Regular vaccinations provide reliable protection. They are made for adults and children from 2 years old. The use of vaccines maintains immunity at the proper level for several years. Next, vaccinations must be repeated.

In the case of a viral form of illness, antibiotics are practically not used, but special antiviral drugs are used. At the moment, we can confidently state the following fact that if the disease is detected in a timely manner and the course of therapy is correctly chosen, no negative consequences will appear. For those who have had meningitis, after discharge from the hospital, systematic follow-up examinations with a doctor at the clinic are recommended: for the first three months every thirty days, and then once per quarter throughout the year. Finally, in the future, the regularity of inspections should be no less than once every six months.

It is urgently required to completely eliminate the use of alcoholic beverages and overcome the addiction to tobacco. If possible, it is recommended to undergo therapeutic courses that stabilize human health in appropriate sanatoriums.

Neuritis - how to protect your nerves

Another type of nervous system disorder is called “polyneuritis,” which is also a consequence of influenza, especially when transmitted on the legs. Typically, the onset of this disease is accompanied by the onset of general weakness in the upper and lower extremities, a slight increase in temperature, and the appearance of aching fingers. Weakening of the limbs can progress to the point of mild paralysis. This condition can be aggravated by impaired swallowing and speech functions.

Most often, after suffering from the flu, the nerves of the face, elbows, as well as the radial and sciatic nerves are affected. When the diagnosis is made, an increased protein content is observed in the cerebrospinal fluid. The disease can last up to three months, but with timely treatment, body functions will certainly be restored.

A more negative version of events develops when the lesion affects the vagus nerve. The threat to human life increases sharply, since the breathing process is seriously disrupted.

Damage to facial nerves is a common complication after infectious diseases. The facial muscles suffer, which is expressed by a distorted mouth, the ability to raise eyebrows exclusively on the healthy side of the face.

Problems with the ulnar nerve exclude the possibility of flexion movements in the metacarpophalangeal joints. The position of the hand is motionless, comparable to a bird's claw.

In cases with older people, after the flu there is often a complication associated with hearing loss, when damage to the nervous system affects the auditory nerve. A person experiences an imperceptible, very gradual deterioration in hearing, but after some time even a quiet conversation becomes inaudible. A persistent sensation of constant tinnitus is created. The result of such a complication may be permanent hearing loss.

In order to cure acoustic neuritis, the recommendations of traditional medicine come down to the use of heat in dry versions - heated sand, warming compresses, heated salt in a cloth bag. However, I repeat that any manipulations with your health based on home recipes are strongly recommended for use only in consultation with a qualified doctor.

1. Prepare a propolis emulsion with oil and alcohol. The use of this remedy eliminates ear noise and restores hearing functions in most cases. The emulsion is prepared as follows:

– Take forty grams of propolis, after crushing it. Place the resulting mass in a glass vessel containing one hundred milliliters of alcohol. Leave for a week at room temperature, shaking the contents every day. Filter, mix the infusion with olive oil in a ratio of 1:4. The mixture must be shaken before each dose.

2. Place a wick made of gauze, soaked in emulsion, in the ear canal for two days. Carry out the procedure with a break of one day, ten times in total.

3. Eating a few slices of lemon daily helps improve auditory function.

4. Combine one teaspoon of birch tar with a glass of warmed milk. It is indicated for use three times before meals. The course of therapy is 60 days. This procedure is very helpful in restoring hearing.

5. Wrap the leaves of fragrant geranium in linen cloth, apply to the place where the pain is felt, attach with a bandage, and cover with something warm on top.

Now a few words about radiculitis, a possible complication of the body, after an unskilled approach to the therapeutic issue in an infectious disease. The recommendations for home treatment given below may help some of you to cope with this illness and improve the health of your body.

1. Collect dandelion flowers in a glass container. Fill the jar with the arranged flowers with vodka in a ratio of 1 to 3, and place it in a place without light for two weeks. Then filter the infusion and rub it on the sore spots. The above tincture has proven itself quite well as a remedy in cases such as bruises, sprains, arthritis, and bedsores.

2. Take 20 grams of crushed tansy flowers, place them in one liter of water that has just been boiled. Wrap the container with a warm cloth, leave for four hours, filter with gauze. Drink the resulting infusion warm, half a glass three times 30 minutes before meals.

3. Take one hundred grams of thyme, put it in a container with one liter of boiling water, cover it with a lid and keep it on low heat for five minutes. After this, filter and pour into a pre-prepared bath. The procedure is performed one hour before bedtime. The duration of the course is two weeks. This bath provides indispensable help for rheumatism of the joints, swelling, and radiculitis.

To reduce the likelihood damage to the nervous system It is necessary to try to eliminate stress and the use of alcoholic beverages from everyday life, pay due attention to the prevention of infectious and non-infectious diseases, and lead a healthy lifestyle.

We have already tried to understand the psychology of the concept “all diseases are from nerves,” but it was the reality of such an expression that interested me. For example, pressure surges or increased heart rate from nervous experiences are a reality, but can the spine or joints hurt if a person is constantly nervous? Or can stress affect the functioning of the digestive system? And it is also believed that in men the genitourinary system reacts especially painfully to stress, but what about this problem in women?
But it seems to me that it is the digestive system, or more precisely the work of the stomach, that most often upsets people during nervous experiences, which subsequently clearly affects the condition of the skin or hair, due to not receiving enough vitamins.

How do you think “nerves” affect a person’s general well-being? What are your options for which organ reacts to stress? And what preventive measures do you use for diseases that can arise from nervous overstrain? I try to rest, sleep is especially helpful, and I drink herbal tinctures with lemon balm or mint, and in the spring I constantly take multivitamins.

The sciatic nerve is the largest and longest nerve in the human body. Its maximum thickness is almost equal to the thickness of the thumb. The sciatic nerve begins in the lumbar spine, where the nerve roots leave the spinal cord, and runs the length of the leg to the toes. The sciatic nerve is formed from five nerve roots. It is formed on the right and left sides of the lumbar spine by a combination of the fourth and fifth lumbar nerves and the first three nerves in the sacral spine.

Each nerve exits the spine between two vertebral segments and is named after the upper one:

• The nerve that exits the spine between the fourth and fifth lumbar segments (L4 and L5, where L is short for lumbar) is called the L4 nerve root, and the nerve that exits the spine between the fifth lumbar segment and the first sacral segment is called the nerve root. L5;
• The nerves emerging from the sacral spine are called the S1, S2 and S3 nerve roots.

These five nerves join together on the anterior surface of the piriformis muscle and become one large nerve, the sciatic nerve. The nerve then travels down the back of both legs, branching to provide motor and sensory functions to specific areas of the leg and foot.

Slightly above the back of the knee, the sciatic nerve divides into two nerves, the tibial and peroneal nerves, which innervate different parts of the lower leg:

• The peroneal nerves run laterally along the outside of the knee to the top of the foot;
• The tibial nerves travel down to the feet and innervate the heel and foot.

The sciatic nerve is responsible for sensation, strength, and reflexes in the leg. If the sciatic nerve is damaged, it can lead to muscle weakness and/or numbness or tingling sensations in the leg, ankle, foot and/or toes.

In most cases, we are talking about irritation and/or compression of the sciatic nerve. The pain and other symptoms that occur with this condition are called sciatica.

Causes

The most common causes of sciatica are:

• intervertebral hernia,
• degenerative changes in intervertebral discs,
• stenosis (narrowing) of the spinal canal in the lumbar spine
• Spondylolisthesis
• Pregnancy
• Tumor in the lumen of the spinal canal

Symptoms

Symptoms of sciatica vary depending on which nerve is being compressed:

• Sciatica due to damage to the L4 nerve root
  Symptoms: pain and/or numbness in the lower leg and foot; weakness may include an inability to lift the foot upward (heel gait). The patient may experience a weakened knee reflex;
• Sciatica due to damage to the L5 nerve root
  Symptoms: The patient may feel weakness when straightening the big toe and sometimes weakness in the ankle (called foot drop). In addition, there is pain and/or numbness in the top of the foot, especially in the area between the big and second toe.
• Sciatica due to damage to the S1 nerve root
  Symptoms: pain and/or numbness along the lateral or outer surface of the foot, weakness, manifested in the fact that it becomes difficult for the patient to raise the heel when walking or walk on the toes. The patient may experience a weakened knee reflex.

There is a wide range in the symptoms of damage to the sciatic nerve, as well as in the type and severity of pain, because they depend on what condition is causing the symptoms. In addition, it is also necessary to take into account the individual characteristics of the patient.

The most common type of pain in the lower extremities with sciatica is characterized by the following symptoms:

• Pain is felt in only one leg;
• Pain begins in the lower back or buttock, radiating down the back of the thigh and usually into the lower leg and/or foot;
• The pain is usually sharp rather than throbbing or aching. Words that people commonly use to describe sciatica pain include “burning,” “sharp,” “sharp”;
• The pain is usually worse when sitting or standing and is relieved when lying down or walking.

There are also conditions that mimic the symptoms of a pinched sciatic nerve. These include:

• Pressure on the sacral nerve roots due to dysfunction of the sacroiliac joint. Symptoms of sacroiliac joint dysfunction may include pain that mimics sciatica or a feeling of numbness. The pain is often described as a severe aching pain in the leg and is not as clearly localized as the pain associated with sciatica;
• Compression of the sciatic nerve in piriformis syndrome. Symptoms of piriformis syndrome may include: pain that mimics sciatica pain and/or numbness in the leg. The pain is usually more severe in the area above the knee, typically begins in the gluteal region rather than the lumbar spine, and is rarely felt in the lower back at all. Piriformis syndrome can mimic the symptoms and signs of sciatica due to a herniated disc, so differential diagnosis is necessary.

Sometimes it happens that the sciatic nerve is damaged due to injury or during surgery, for example, when inserting implants into the spine. In this situation, symptoms of sciatica also develop, and in some cases we can talk about sciatic nerve palsy, in which there is serious loss of sensitivity in the leg and foot and atrophy of the muscle tissue of the leg. At the same time, the leg seems to “lose weight” and becomes smaller in volume than a healthy leg.

In many cases, sciatica goes away over time. Initial treatment usually focuses on medication and specific exercises.

What can help reduce pain when the sciatic nerve is damaged?

• sit less;
• short walks. We recommend gradually increasing the distance you can walk without pain;
• special gymnastics for the spine
• do not work at the computer for a long time. If this is necessary, then you need to take a break from work every 15 minutes, walk around or do gymnastics during the break.
• Organize your workplace correctly so as not to sit leaning forward.
• use of bolsters under the back.
• proper organization of the work-rest regime.
• normal sleep duration of at least 8 hours
• sleep on an orthopedic mattress, we recommend using natural latex mattresses (not spring)

Risk factors for sciatic nerve damage

• Age. Age-related changes in the spine, such as intervertebral hernias and bone spurs, are the most common causes of sciatica;
• Obesity. Excess weight puts more stress on the spine, which can lead to changes in the spine;
• Nature of activity. Carrying heavy loads, twisting movements of the back, and driving increase the load on the spine and can contribute to the appearance of sciatica;
• Prolonged sitting. People who sit for long periods of time due to the nature of their work or simply lead a sedentary lifestyle are more likely to suffer from sciatica than active people;
• Diabetes. This condition increases the risk of nerve damage.

Treatment

Additional treatment for sciatica depends on what is causing the nerve irritation. If your symptoms do not disappear, then you need to consult a neurologist.

During the examination, the neurologist will determine the degree of change in neurological symptoms and reflexes, for example, Lasegue's symptoms, Achilles reflex, determine the level of neurological damage, the presence of hypotrophies and atrophies of the muscles of the back and legs.

You can begin treatment for sciatic nerve pathology only after additional diagnostics.

Since the primary causes of pinching of the sciatic nerve are intervertebral hernia and protrusion of the intervertebral disc, diagnosis should begin with an MRI using a high-field machine. In the future, CT or ENMG may be necessary, but the need for these studies arises extremely rarely.

If you have pain in the lower back and leg, then you can sign up for a consultation at one of our Clinics (consultation for citizens of the Russian Federation is free).

Stupid questions are a great way to learn more about the world. And, if you think about it, they are not so stupid, and curiosity has always been one of the main properties of a person.

Today we are in website imagined what would happen if all the people on Earth jumped at the same time.

For the purity of the thought experiment, let’s gather all the people in one place - for example, on a piece of Earth with an area of ​​1 thousand square meters. km, the size of New York. And yes, imagine, we can all fit there.

• Let's say the mass of 1 person is 60 kg (let's not forget about children and residents of Asian countries, who generally weigh less than Europeans).
• There are 7.5 billion people living on Earth. It turns out that the total mass of humanity is about 450 million tons.
• The mass of the Earth is about 6 sextillion tons, that is, 6,000,000,000,000,000,000,000 tons.

It turns out that the percentage of the weight of all people from the weight of the Earth is approximately 0.000000000000001%, that is, almost zero. As you can see, there are not as many of us as it seems on a planetary scale. Physicist Rhett Allain calculated that the energy from our jump would not be enough to cause something global. But:

• One of the most noticeable effects to us will be the sound of billions of feet hitting the ground at the same time, this hum will last for several seconds.
• We will still move the planet! But only by about 0.25 nanometers. This is half the diameter of a hydrogen atom, the smallest atom in the world. This shift will be completely unnoticeable, and the Earth will almost immediately return to its normal position.

By the way, there is another opinion, which was presented by astrophysicist Paul Sutter and physicist Mark Boslough. According to their scenario, the effect of the jump of all humanity will be much more noticeable:

• They believe that the sound from the landing of all humanity on the asphalt will be so loud (200 dB) that it can rupture eardrums and even kill.
• A shock wave will arise, which will generate an earthquake of magnitude 4–8, which will cause the destruction of buildings and create a tsunami.

Which of these points of view to accept is up to you. Personally, we thought the first one was more realistic. Or maybe there are physicists among you who can make their own calculations?

By the way, there was an example in history when an earthquake with a large magnitude had a global effect on the planet. Scientists from NASA said that the Earth's orbit shifted by several centimeters and the day shortened by a millionth of a second after the powerful earthquake in Japan in 2011.
