I am suffering from mouth ulcer since three days and i don't feel like it's getting better. Blisters were there on my tongue which now inflamed and the front portion of the tongue became completely red. I am not able to eat anything and can't speak also. It's very irritating also. I applied the zytee gel but it's burning and irritating my tongue more. I was taking becosules capsules also which is not doing any help i guess. What could be the cause and what remedies and medicines to take?
