Dear doctor, I am having severe ulcer in my mouth and tongue. I had consulted dentists and general physician. Antibiotics, vitamin supplements and gel gave me little better. But the small lump under tongue is causing pain. Past 3 weeks I couldn't able to eat the normal food. Whenever I tried to eat some food or even biscuits or bread also give pain in both side of mouth with lesion. Please tell me the reason for this pain. And there are white patches in side of my tongue. Do I need to check further. I have no issues in digestion or any acid reflux.
