I am also on Nortriptyline. I am going off because of side effects. It is an older drug primarily used for depression but also for it's pain relieving qualities. My doc hates it. It causes weight gain and for me too many head games. Short term memory etc. I also had numerous dental work done , saw dentist at least 7 times for tooth pain, had two root canals, endontist and oral surgery. Ended up pulling two teeth. If you havent already please go to TNA site and read some of the articles.http://www.tna-support.org/ Another idea is to go to this site and take the test. It is very helpful https://neurosurgery.ohsu.edu/tgn.phpl. Trust me no doctor wants you to have TN. You may have some pre TN symptoms, no one can tell. My doc also put me on trileptal because it has less side effects than tegretol, but it is a sister drug to it. Since you are getting off the drug, be conscious of your pains. See if the are better worse or the same. I really hope that it is not TN for your sake. Keep us up to date on what's going on with you. Take good care, Jen
