[[Trigeminal neuralgia]] (TN), a [[neuropathic pain]] [[syndrome]], is defined by the [[International Association for the Study of Pain]] as "a sudden and usually unilateral severe brief stabbing recurrent [[pain]] in the distribution of one or more branches of the [[trigeminal nerve]]
((Garg RK, Malhotra HS, Verma R. Trigeminal neuralgia. J Indian Med Assoc. 2011;109:631–636.)).

Also known as prosopalgia, or Fothergill's disease.

The clinical association between TN and [[hemifacial spasm]] is the so-called [[tic douloureux]].

It has been described as among the most painful conditions known to mankind.

Trigeminal neuralgia and deafferentation neuropathic pain, or [[trigeminal neuropathy]], are different symptomatologies, rarely reported to present together.
