Neuralgia is a syndrome characterized by pain along the nerve, and hyperesthesia in innervated region.
Etiology infections (influenza, malaria, fever and others), intoxication (alcohol, privrzenost and others), changes of the spine (deforming spondylosis, osteochondrosis), metabolic disorders (diabetes). The main symptom neuralgia - paroxysmal pain of varying intensity and duration in the course of the respective nerve trunk. The character of pain often sharp, shooting, vomiting, sometimes with a sense of stinging, then gradually the pain can go to blunt, in the intervals between attacks may be missing. Pain caused by irritation of the nerve fibers of the inflammatory process in the nerve or the surrounding tissues.
The most frequently observed sciatic nerve, at least - intercostal neuralgia. When neuralgia sciatic nerve (ischialgia) the pain is localized in the area of the buttocks, the back surface of the hips, back and outer surface of the leg, in the foot (see Sciatica). Nerve trunks painful pressure. When lifting the outstretched legs of the sciatic nerve is stretched and leg pain increases (symptom Lasaga); pain also increases with the seat in bed with your legs extended and movements.
Neuralgia intercostal nerves in most cases has a secondary character and occurs in a variety of infections (influenza, tuberculosis, and others). Clinically characterized by permanent or paroxysmal pains along the intercostal nerves.
In the area of innervation of the relevant nerves found an increase or decrease of surface sensitivity. For further diagnosis intercostal neuralgia is necessary to eliminate the diseases of the internal organs (lungs, pleura, liver and other), lesions of the spine, shells or substance of the spinal cord.
Neuralgia of the trigeminal nerve often begins during one of its branches. Characterized by episodic pain that lasts anywhere from a few seconds up to 1 - 2 minutes May be redness half of the face, eyes, twitching of muscles of the face. Some patients seizures rare and pain blurred, some attacks are frequent, excruciating pain. More often appear pain during movement of the lower jaw, the air temperature changes, touching certain parts of the face (algogennah zone). Look sick characteristic: set face, anxious glance.
Between bouts of pain may not be or are dull, aching pain, burning and itching sensation in the area of the tongue, gums. In the further process can spread to other branches of the nerve.
Neuralgia small and large occipital nerve is expressed in pain in the neck when the pressure on the nerve trunks, turning and bowing the head (more common with cervical osteochondrosis). When neuralgia language and language-pharyngeal nerve pain and paresthesia (see Sensitivity) are in the tongue, the throat, can irrationality in the ear. There is this neuralgia with osteochondrosis III cervical vertebra, tumors V and IX pairs of cranial nerves, stomatitis.
Treatment. You must treat the underlying disease. Symptomatically appoint acetylsalicylic acid (aspirin) 0.3 g 3 times a day, amidopyrine (pyramidonum) 0.25 g 3 times a day, analgin 0.5 g 2 times a day. Vitamin B1 - 3% solution of 2 ml intramuscularly at the rate of 25 injection, B12 200 mcg intramuscularly 25 injection (not recommended drugs). Thermal procedures, after the acute period - paraffin, diathermy, electrophoresis with novocaine, massage, Spa treatment (mud, radon, hydrogen sulfide baths), with professional neuralgia - remove harmful factor and transfer to another job. When neuralgia of the trigeminal nerve in addition to these measures give tegretol (tablets), used alcoholism nerve, in the most severe and long-term recurrent cases surgical treatment.
