I can't even have a premade sandwhich anymore. The pain feels like an explosion, with a constant burning afterwards taking at least an hour before it goes away. Especially my tongue hurts so much, that talking is becoming difficult. I have been tested on allergies, nothing came out. I am seriously getting crazy of the tasteless food I have to eat in order to not have the pain. Doctors have seen my mouth when it hurted, but they can't find anything. No swollen or red mouth, just pain. I would really appreciate it if somebody could answer my question.
