What is meant by neuralgia?
Neuralgia is a clinically descriptive term, meaning intermittent pain in the distribution of a nerve or nerves. The condition described as “sciatica” may be due to the injury of the sciatic nerve, but is more commonly due to spinal nerve root compression (L5 or S1); pain is felt in the distribution of the sciatic nerve (radiating down the posterior aspect of leg). Trigeminal neuralgia, one of the most common primary neuralgias, is characterized by a jabbing pain in one or more of the distributions of the trigeminal nerve. Postherpetic neuralgia may occur after an outbreak of acute herpes zoster (shingles). Neuralgias are characteristically associated with an electrical, shock-like pain.
