Kevin,
Kind of sounds like thrush-yeast infection in your mouth. The burning when eating or drinking anything is how I feel when I get it. Meds cause it esp prednisone. Sugar will really make it burn if that's what it is. Can cause sores, bumps and "peeling" in the mouth. My doc usually gives me diflucan for it or mycolex tablets that you suck on and taste like yuck. TNF's can cause it too, along with the dry mouth. Someone else suggested Biotine and that does help. Alcohol can cause it or make it worse. Hope it gets better! Peace&Light
