Trigeminal Neuralgia
Symptoms and Signs of Trigeminal Neuralgia
Pain due to trigeminal neuralgia occurs along the distribution of one or more sensory divisions of the trigeminal nerve, most often the maxillary. The pain is paroxysmal, lasting seconds up to 2 minutes, but attacks may recur rapidly—as often as 100 times a day. It is lancinating, excruciating, and sometimes incapacitating. Pain is often precipitated by stimulating a facial trigger point (eg, by chewing, brushing the teeth, or smiling). Sleeping on that side of the face is often intolerable. Usually, only one side of the face is affected.
