Pain. What is this feeling - everyone knows. Despite the fact that it is very unpleasant, its function is useful. Indeed, severe pain is a signal of the body, which is aimed at attracting the attention of a person to problems in the body. If the relationship with him is in order, then you can easily distinguish the pain that occurred after exercise from the one that appeared after a very spicy dish.
Most often, it is divided into two types: primary and secondary. Other names are epicritic and protopathic.
Primary pain
The primary is pain, which is directly caused by any damage. It can be a sharp pain after a needle prick. This type is very sharp and strong, but after the exposure to the damaging object ceases, the primary pain immediately disappears.
It often happens that the pain after the disappearance of the traumatic effect does not disappear, but acquires the status of a chronic disease. Sometimes it can persist for so long that even doctors are not able to determine the reason why it originally arose.
Secondary pain
Secondary pain is already pulling in nature. It is very difficult to indicate the place in which it is localized. In such a situation, it is customary to talk about a pain syndrome that requires treatment.
Why does pain occur?
So, a person has secondary pain. What is this syndrome? What are its reasons? After tissue damage occurs, pain receptors send an appropriate signal to the central nervous system, that is, the brain and spinal cord. This process is associated with electrical impulses and the release of special substances that are responsible for the transmission of nerve signals between neurons. Since the human nervous system is a rather complex system with many connections, there are often malfunctions in controlling the sensations associated with pain, in which neurons send pain impulses even when there are no irritants.
Localization of pain
By localization, the syndrome is divided into two forms: local and projection. If the failure occurred somewhere on the periphery of the human nervous system, then the pain syndrome almost exactly coincides with the damaged area. This may include pain after visiting the dentist.
If a failure occurred in the central nervous system, a projection form appears. These include phantom, wandering pains.
Depth of pain
According to this characteristic, visceral and somatic are divided.
Visceral pains are sensations from internal organs.
Somatic pain is perceived as joint, muscle and skin pain.
There are symptoms in which you need to urgently respond.
Very severe, sharp pain in the head, which was not previously observed
In this case, you must immediately consult a doctor. This can be both a pain from a cold, and a brain hemorrhage, which is already much more serious. If there is no confidence in the reason that caused such a sensation, then you need to undergo a medical examination or call an ambulance. Treating acute pain before its cause is identified is not a good option. The main symptom is that the sensation passes before the damage heals. Correct diagnosis is very important.
Sore throat, chest, jaw, arm, shoulder, or abdomen
If there is chest pain, this may be a bad sign of pneumonia or a heart attack. But you need to know that with heart disease there is usually some discomfort, not pain. What is discomfort with such diseases? Some complain of squeezing in the chest, as if someone is sitting on top.
The discomfort associated with heart disease can be felt in the upper chest, as well as in the jaw or throat, left arm or shoulder, and also in the abdominal cavity. All this can be accompanied by nausea. So, if a person constantly experiences something similar and knows what is at risk, you need to urgently check. Indeed, very often people lose time, because they misinterpret the symptoms of pain. Doctors say that the discomfort that occurs from time to time should also be taken seriously. It may be associated with physical exertion, emotional distress, or excitement. If this is tested after work in the garden, and then passes during rest, then this is most likely angina pectoris, which attacks most often occur in hot or cold weather. Discomfort and pain in women with cardiovascular diseases are implicit. They can disguise themselves as symptoms of diseases of the gastrointestinal tract, which include discomfort in the abdomen, bloating. After the onset of menopause, the risk of such diseases increases sharply. Therefore, you need to be attentive to your health.
Pain in the lower back or between the shoulder blades
Some doctors say this is a sign of arthritis. But you should keep in mind other options. It may be a gastrointestinal disease or a heart attack. In a particular case, aching pain in these places may be a symptom of aortic dissection. In people who are at risk for diseases associated with the heart and blood vessels, organ integrity may be impaired. Such people include those who have excessively high blood pressure, circulatory problems, as well as smokers and people with diabetes.
Severe abdominal pain

Risk factors are old age, cancer, low mobility after prolonged bed rest, obesity, pregnancy. Sometimes there is no pain, but there is only swelling. In any case, it is better to seek help immediately.
Fever in the legs
This problem is familiar to many diabetes patients. It was for her that this dangerous disease was identified. Some people do not know that they have diabetes. So the fever in the legs is one of the first signs. A tingling or burning sensation in the legs is felt , which may indicate damaged nerves.
Multiple pains, as well as combined
A variety of physical, painful symptoms often occur in depressive states. Patients may complain of soreness in the limbs or abdomen, diffuse pains in the head, and sometimes all together. For the reason that unpleasant sensations can be chronic and felt slightly, patients and their relatives can simply ignore such symptoms. And the stronger the depressive disorder, the more difficult it is for a person to describe the sensations. Pain after psychological trauma is often difficult to explain. This can be confusing for doctors. That is why it is necessary to identify other symptoms before making a diagnosis of depression. If interest in life is lost, you cannot think and work with high efficiency, and quarrels with people also occur, you need to get the help of a doctor. When something hurts, one does not have to endure silently. After all, depression is not just a deterioration in the condition and quality of life. She must be treated very actively until she has time to cause major changes.

All of the above types of pain are dangerous, as they can be symptoms of serious illness. Therefore, at the slightest sign, you should immediately seek help from doctors. After all, the essence of pain lies in the fact that a person understands that something is wrong in the body. In addition to unpleasant sensations and significant changes in the human body, pain can lead to sad consequences, the worst of which is fatal.
