Definition: Sharp pain in a nerve or along a nerve pathway. The pain of neuralgia is often described as throbbing, stabbing, shooting, jabbing, sudden and repetitive.

In multiple sclerosis (MS), neuralgia is caused by demyelination, that disrupts the normal signal of the nerve and causes pain. This symptom often starts as tingling or “pins and needles,” followed by a sensation of an electric shock.

Trigeminal neuralgia affects the nerves of the face.
