I have had AT2 for 2 1/2 years. It is the worst pain I can describe. It is like a dry socket in my entire mouth. They have tried injections, antiseizure medications, and opioids. I have just been in a constant suffering with the exception of the times the opioids have helped very little until eventually my tolerance with the medications builds to the point it seems nothing helps. The doctors basically say I am untreatable.
