Trigeminal neuralgia

Trigeminal neuralgia, also known as painful tic, sometimes called "facial pain," and referred to as "facial wind pain" in traditional Chinese medicine, refers to severe pain occurring in the distribution area of the trigeminal nerve on the face. Trigeminal neuralgia often has sudden onset and sudden cessation. It is a non-neuropathic, unbearable neuropathic pain disease characterized by knife-like, burning, and intractable pain. The incidence of trigeminal neuralgia is high, with onset mostly after age 40, and it is more common in women than in men. The incidence rates reported domestically and internationally are 47.8/100,000 and 62.6/100,000, respectively. The incidence can increase with age.
