Trigeminal neuralgia (TN) presents as a stabbing unilateral facial pain that is triggered by chewing or similar activities or by touching affected areas on the face. The disorder affects the right side of the face 5 times more frequently than the left.

According to Fromm et al, some patients may present with pretrigeminal neuralgia syndrome for a period of weeks or even years before developing the customary symptoms of trigeminal neuralgia. [15] They complain of an unrelenting sinus pain or toothache lasting for hours, triggered by moving the jaw or drinking fluids. Not surprisingly, they first seek dental care. Some find benefit from baclofen or carbamazepine.
