question: My tongue and the roof of my mouth feel hot. I have a slight white coating on my tongue and the tip of my tongue feels very sensitive like I cut it or something. I did receive some nystatin oral, and 5 Diflucan pills but it still there more than ever.  I did suck on a lot of popsicles this summer and keep thinking did I do freezer burn damage? It wasnt on the roof of my mouth until today. I did finish all my medication two days ago. I seem to be chewing on my tongue at its sides and recently had a cancer sore under my tongue. I am miserable, please help.
