With local pain, incl. with some neuralgia, local anesthesia is sometimes appropriate.
Unpleasant, sometimes unbearable sensation, which occurs mainly with strong irritating or destructive effects on the human body. Pain is a signal of danger, a biological factor that ensures the preservation of life. The occurrence of pain mobilizes the body's defenses to eliminate painful irritations and restore the normal activity of organs and physiological systems. But at the same time, pain brings a person severe suffering (for example, Headache, Toothache), deprives him of peace and sleep, and in some cases can cause the development of a life-threatening condition - Shock.
For persistent exhausting pains in patients with chronic .
Usually the pain is stronger, the more severe the damage to the skin, mucous membranes, periosteum, muscles, nerves, i.e. the higher the intensity of the stimuli. In case of violations of the function of internal organs, pain does not always correspond in strength to the degree of these disorders: relatively minor disorders of bowel function sometimes cause severe pain (colic), and serious diseases of the brain, blood, and kidneys can proceed with practically no pain.
However, with the unspecified nature of the somatic disease, especially with unclear abdominal pain, the use of analgesics is contraindicated due to a possible modification of the clinical picture, which complicates the diagnosis of the disease, in which urgent surgical intervention may be indicated (see Acute stomach).
The nature of the pain is varied: it is assessed as sharp, dull, stabbing, cutting, pressing, burning, aching. The pain can be local (felt directly at the site of the lesion) or reflected (occurs on a part of the body more or less distant from the site of the lesion, for example, in the left arm or scapula with heart disease). A peculiar form is the so-called phantom pain in the absent (amputated) parts of the extremities (foot, fingers, hand).
Diseases of the nervous system are often the cause of pain of various kinds. The so-called central pains can be caused by diseases of the brain. Particularly severe pain is observed after a stroke, when the lesion is located in the optic tubercle; these pains extend to the entire paralyzed half of the body.
The so-called peripheral pain occurs when painful endings (receptors) are irritated in various organs and tissues (myalgia - muscle pain, arthralgia - joint pain, etc.). According to the variety of factors acting on pain receptors and causing their irritation, the frequency of peripheral pain in various diseases and intoxications is also high (myalgia - with influenza, arthralgia - with rheumatism, rheumatoid arthritis, etc.).
With damage to the peripheral nervous system, pain is the result of compression, tension and circulatory disorders in the root or trunk of the nerve. Pain associated with damage to peripheral nerves is usually aggravated by movement, with tension on the nerve trunks. Following the painful sensations, as a rule, there is a feeling of numbness, impaired sensitivity in the area where the pain was experienced.
Pain in the region of the heart, in the left side of the chest or behind the sternum can be stabbing, aching or squeezing, often radiates to the left arm and shoulder blade, appears suddenly or develops gradually, it is short-term or long-term. Sudden sharp squeezing pains behind the sternum, radiating to the left arm and scapula, arising during exercise or at rest, are characteristic of angina pectoris (Angina pectoris).
Often, pain in the heart area is caused by functional disorders of the nervous apparatus of the heart with neuroses, endocrine disorders, various intoxications (for example, in smokers and alcohol abusers).
Pain in the region of the heart can also occur in school-aged children, for example, due to the increased emotional stress of the child. The pain is usually mild and short-lived and comes on suddenly.
A child who complains of pain in the region of the heart should be put to bed, given a sedative (for example, tazepam, sibazon 1/2 tablets), analgin 1 / 2-1 tablet, but 1 / 2-1 tablet. In cases where these measures do not have an effect, you should call an ambulance. With recurring pains in the heart area among seemingly complete health, you need to consult a doctor and examine the child.
Abdominal pain occurs in many diseases, including those requiring urgent surgical treatment (see. Abdomen). 1) a kind of psychophysiological state of a person, arising as a result of exposure to superstrong or destructive stimuli that cause organic or functional disorders in the body; is an integrative function of the body, mobilizing a variety of functional systems to protect the body from the effects of a harmful factor; 2) (dolor; synonym painful sensation) in the narrow sense is a subjectively painful sensation, reflecting the psychophysiological state of a person, which occurs as a result of exposure to superstrong or destructive stimuli.
