Neuralgia - acute or paroxysmal burning, aching, dull pain along the nerve. The cause of the disease neuralgia can be very nerve, nerve plexus, spinal cord or pathological processes developing in the tissues and organs near the nerve.

The most frequent trigeminal, occipital, intercostal nerves and the sciatic nerve.

Trigeminal neuralgia can occur as a complication of certain diseases or as an independent disease. Trigeminal nerve has three branches: one branch goes to the skin of the forehead, the second - on the cheek, nasal mucosa and the teeth of the upper jaw and the third - the lower jaw and teeth.

When neuralgia occipital nerve pain spread from the neck to neck. If intercostal neuralgia shooting and burning pain arises in the course of the intercostal spaces.

Typical symptoms of the disease sciatic nerve is a pain in the buttocks, extending to the rear surface of the femur and tibia, and sometimes reach the foot, numbness in the skin of these areas and weakness (up to paralysis) of leg muscles, as well as a sharp pain and involuntary muscular contraction when lifting and straightening legs the supine position. All these symptoms are due to functional features and location of the sciatic nerve, which starts from the sacral nerve plexus, passes underneath the buttocks through the back of the thigh, but a little short of the popliteal fossa, bifurcates into two descending branches. The sciatic nerve provides cutaneous sensitivity of the respective zones, conducts motor impulses to muscles, extensor trunk and hip flexor leg and up the foot. The main cause of illness is his sciatic nerve compression, called tunnel syndrome. To him may cause some diseases of the spine and joints, flat feet and even unsuccessful injections in the buttocks.

Sciatic nerve block - companied by moderate pain, but violates the transfer of motor impulses. They can lead to muscle atrophy, paralysis, as well as to the appearance of dry skin and venous ulcers on the feet. Disrupt the activities of the sciatic nerve may be some metabolic diseases: diabetes, certain thyroid diseases, and various poisonings.

Treatment of various neuritis must begin with the establishment of their causes, and then have to start treatment.

In addition, traditional recipes to improve hair growth are calculated on a very long-term use, whereas treatment with drugs gives a positive result for a much shorter time.
