I also suffer from BMS brought on when an endodontist gave me a shot that injured the trigeminal nerve. That was 6 very long years ago. Gabapentin helped in the beginning as did oral Clonopin and Lyrica. Then their efficacy
wore off. Cymbalta has made some improvements. The nerve damage also radiates on one side of my face and lip. I'm so sorry for your pain because I understand. It has been a life altering event that most people don't have a clue about much less compassion. These are things that have helped me: dental gum sticks, dental floss, toothpaste for sensitive teeth, ice packs, heat packs, lidocaine, Benzo-gel, ice cream and for some unknown reason (for me at least) peanut butter milkshakes. I also drink ice water constantly. I've been told that CBT is helpful as would be medical marijuana. I've been to countless doctors and dentists and pain clinics. It seems like the pain has a circadian rhythm to it worsening in the afternoon into the evening. The pain causes such exhaustion. A good acupuncturist may be able to help you.
