Michael,
I had a lot of the neuralgia you are describing and it did wake me up at night. There is medication you can take for it but it will make you sleepy -- I chose not to take it but if it is really making you nuts, then ask your doctors. I looked at it as a good thing because it meant that the nerves were regenerating and that maybe my smile would come back. After almost six months it did -- so try to hang in there. There may be good stuff coming from this discomfort.
