Well, I am stumped- You could call me a veteran vaperer as I am nearly 2yrs into it. I developed a sore throat 3 weeks ago as well as a sore ear, only to find out that this 'sore throat' was an ulcer underneath my tongue. Meanwhile, my doctor has prescribed 2 courses of antibiotics as well as Acclovir for ulcers. It has shrunk a bit, but still not gone. At this stage I am thinking serious problems (like the big C) etc. I have also used mouthwash,baking soda, kenalog in orabase and it will still not let up. I also have a tenderness to the roof of my mouth as well as tongue. My whole mouth is sore! I have stopped my beloved Kona coffee vape, as I think that could be an additional culprit to my agony. I am seeing my dentist this afternoon- hopefully I don't need to stop vaping, as I really do not want to go back to cigarettes. Please help-
