When I first had the pain, I went to my dentist and he x-rayed my mouth and found nothing wrong with my teeth. He recomended that I see an oral surgeon because maybe the problem was with my jaw. They found nothing - no TMJ, etc. I went to my family doctor and told her where I have been and they all found nothing. By this time, the pain was so bad that eating was a problem (I could not chew, I was on a liquid diet). I could not brush my teeth and sometimes I could not talk. My doctor refered me to a neurologist and I went on Tegretol and with in a few days the pain was gone. It was like a miracle!!!
