Since June 2011 I have had my back 4 lower left teeth all crowned (1 root canal ) and upper left back 2 teeth (again 1 root canal ).......then 2 weeks ago the pain started in my lower left jaw/teeth of a much more severe and 'striking' nature. Crippling, drop to your knees, can't speak pain. Now me and my dentist don't know what the real reason for the TN is. Caused by dental treatment or because of TN. My GP also does not know either. Tegretol helping. Actually so much so I can't almost beleive how bad it was. I do however remember stating i could not live with this pain.
I also get about 4 migraine over left eye per year and don't yet know if connected (awaiting nuro appt). Seems many of our stories are similar.
