<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am suffering from Mouth ulcer from last two months. visited couple of doctors and they are giving me regular vitamin tablets and vitcofol injection. though i am telling them that it is due to my chewing tobacco uses.Now my both side of inner tongue has burning sensation. it gets cure for a week and than resurfaces  <response>: You did not mention the rough size of the ulcer and its presence elsewhere. QUIT tobacco immediately. This can be a leukoplakia. A biopsy is necessary to confirm the diagnosis and to check for any dysplasia changes. Follow a healthy diet and the vitamin tablets prescribed by the doctor. Get a professional scaling done. Maintain proper oral hygiene and healthy diet. It must be cleared after u quit chewing tobacco in few months. Regards.
