Regarding TMJ, many patients with TMJ problems present with facial
pain, and by treating the TMJ the facial
pain improves significantly, so it may be important for you to discuss with your dentist or oral physician, how will be the best treatment for your TMJ, and if this is causing your facial pain.
Unfortunately as I said, without being able to obtain a detailed history and physical examination as well as neurologic examination, I cannot tell you what the cause of your symptoms is.
