<s>[INST] I have a burning/stinging feeling on my tongue and roof of my mouth. Have had it before but my tongue had a white film on it and was swollen a bit. I was given a mouth rinse that they normally give to cancer patients. It went away after about a week. I dont have the white film or swollen tongue but do have the burning/stinging sensation.. Would like to get rid of the problem, not mask it by getting the mouth rinse again. Can you help me? Thank you...... [/INST] Hello, Thank you for consulting with Chat Doctor. Actually there are many causes of burning sensation in tongue-It can be possible that you are having some habit of tobacco chewing or smoking because of which there are pre-malignant changes present and these are causing this burning sensation.-or it can be possible that you are having some candida infection thrush which is causing this infection.in first case you should start with some antioxidants like lycopene.in another condition you have to start with antifungal medication. Hope it will help you. </s>
