<s>[INST] 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. [/INST] Hello, Thanks for consulting Chat Doctor, Read your query as you have white coating on tongue and feeling of hot on tongue and roof of mouth this can be due to oral thrush don't worry about this I will suggest you to consult oral surgeon and go for examination and in meantime you can apply candid gel on tongue and for cancer sore you can apply ointment McCoppin or mugel on ulcer. Hope this will help you. </s>
