I've had this sensation before whenever I eat a citris or sour fruit, however, lately after consuming any alcohol
such as beer, wine, and margaritas, etc., I get this sharp, excruciating pain after just one glass. It hurts so badly, especially if I drink water. The moment the H2O hits the jaw part of my inner mouth, a burning sensation immediately follows. Now, here's the strange part, if I drink another glass of alcohol the pain will subside instantly.
