Trigeminal neuralgiaTrigeminal neuralgia
is a disorder of the trigeminal nerve
(the fifth cranial nerve
) that causes episodes of intense, stabbing, pain resembling an electric shock in the areas of the face where the branches of the nerve are distributed - the eyes, lips, nose, scalp, forehead, upper jaw, and lower jaw. Gloria Steinem
contracted the disease in 1994
. The American philosopher Charles Sanders Peirce
suffered from "facial neuralgia" now called trigeminal neuralgia, from his college years onward.
