Neuralgia
Neuralgia , noun
[New Latin, from Greek ney^ron nerve + {not transcribed} pain. See nerve.]
(Medicine) A disease, the chief symptom of which is a very acute pain, exacerbating or intermitting, which follows the course of a nervous branch, extends to its ramifications, and seems therefore to be seated in the nerve. It seems to be independent of any structural lesion. — Dunglison
