Neuralgia is an umbrella term for any type of throbbing, or paroxysmal, pain that extends along the course of one or more of the peripheral nerves. Neuralgia is classified by both the part of the body affected and the cause. In some cases, doctors can’t find cause; in others, the cause is an infection or underlying disease, such as arthritis, diabetes or syphilis. Tumors, both cancerous and benign, can cause neuralgia, as do structural problems in which nerves become compressed or pinched. Sciatica, the throbbing pain that can extend from the lower back and buttocks to the feet, is one of the most common examples. Various medication as well as arsenics and other toxins, can also produce neuralgia.
Deficiencies of the b-complex vitamins can result in neuralgia involving numerous nerves throughout the body, a condition known as polyneuralgia or polyneuropathy. This condition often occurs in alcoholics whose diet is generally poor. A deficiency of thiamine- a b- complex vitamin found in various animal products are fortified cereals, breads, and other grains products is especially common among alcoholics, who may suffer from nerve pain as well as muscle weakness. Their treatment starts with detoxification, to rid the body of alcohol, and high-dose thiamine supplements. As recovery progress and the diet improve, the supplements can gradually be decreased.
