I haven't had surgery (yet) for my AN, but I have had tongue pain AND gum pain for about 8 months now. It's horrible. Mine isn't so much shooting pain, but feels almost like burning, though had one tooth that was bothering me in the back that they suggested a root canal for (if you ask me, they say/do that a little too quickly!). I have had it looked at from an oral surgeon, because I thought it had to be something they could treat. Only to be told there is nothing there, like I was nuts. So, it's clearly a nerve issue. When you look at pics of AN, and all the places it could be sitting in that small area, there are SO many nerves that can be affected. I think that the usual nerves (facial and hearing) are the obvious suspects and what you hear most about, but the mouth, tongue, gums, even teeth can feel it as well. I've been researching this for months, and there is no doubt. They gave me neurontin as well, but I have yet to take it. Does it help at least with the nerve pain in your head? How much do you take a day?
Sorry for your pain. :-(
