OK...So this is the most painful sore I have EVER had.  I woke up with a what appeared to be a canker sore on my pallet...the little mucus skin area in the back of the throat. After nearly a week, I couldn't take it anymore.  My dr prescribed this chalky mouthwash that make me want to throw up howevr...it worked quickly. It hurt SO bad...now I'm getting a recurring, very painful blister, in the same spot inside my nose.  It has never opened up or drained or anything. What the heck.  I'm not some teenager who's out doing "teenage" stuff.  I DO NOTHING...work, sleep, gym, repeat!  WTH??????????
