"TN (Trigeminal Neuralgia) is a pain that is described as among the most acute known to mankind. TN produces excruciating, lightning strikes of facial pain, typically near the nose, lips, eyes or ears.
TN (Trigeminal Neuralgia / tic douloureux) is a disorder of the fifth cranial (trigeminal) nerve that causes episodes of intense, stabbing, electric shock-like pain in the areas of the face where the branches of the nerve are distributed - lips, eyes, nose, scalp, forehead, upper jaw, and lower jaw. By many, it's called the "suicide disease". A less common form of the disorder called "Atypical Trigeminal Neuralgia" may cause less intense, constant, dull burning or aching pain, sometimes with occasional electric shock-like stabs. Both forms of the disorder most often affect one side of the face, but some patients experience pain at different times on both sides. Onset of symptoms occurs most often after age 50, but cases are known in children and even infants. Something as simple and routine as brushing the teeth, putting on makeup or even a slight breeze can trigger an attack, resulting in sheer agony for the individual. Trigeminal neuralgia (TN) is not fatal, but it is universally considered to be the most painful affliction known to medical practice."
So I definatly have TMJ and crunching/popping when i open my mouth somtimes I have TMJ swelling, but only on one side of my face and from time to time for 1-2 minutes randomly in a week i'll get an agonizing feeling of someone putting a livecircuit on my face (to have jolts of electricity go up my jaw every few seconds for 30sec-2min)
Its agonizing but I barely ever get it and its dealable in short-doses. If I have it, it would be the less typical form that results in a constant dull ache somtimes electrical lightning feelings.
