Neuralgia

Neu‐ral″gi‐a (?), n. [NL., from Gr. νευ̑ρον/ nerve + ἄλγοσ pain. See nerve.] (Med.) 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.
