[|Human|] Hi My name is abhijit and am from India. I have a mouth ulcer inside my cheeks, close to my upper right cheek. It looks like a slight hardedned layer which does not pain. The ulcer has been there for 3-4 weeks now, i have also visited my office doctor and another physician, they had put me on to folic acid and vitamin b12 tablets and it turned out i have vitamin b12 deficiency my readings show below 159 and the average is between 230 and 900. After it was diagnosed i have been taking b12 shots, have been told to take 5 continous shots and after that once a week for 5 weeks. The ulcer remains the same and also I have a soreness in my cheeks on the same side, it feels like a set of hard lines on the inside of teh cheeks.I used to smoke earlier but 1-2 cigarettes a day, i have quit since a month. I had even spoken to the doctors about oral cancer, they ruled it out saying its a zinc, iron/b12 vitamin deficiency.Can you help me out with what it could be as am in a lot of stress and keep thinking about this..
[|AI|]  Hi, Thanks for writing in. The symptoms of oral cancer includes the followingWound in the mouth that doesn't heal. Swelling, lump or thickening of the skin or lining of your mouth. Presence of white or reddish patch on the inside of your mouth. Loosening of teeth. Poorly fitting dentures if you wear it. Tongue pain. Pain in the jaws with inability to open the mouth without discomfortDifficulty or pain during chewing. If a doctor has examined the mouth ulcer you have been having for 3 to 4 weeks and diagnosed it as a vitamin deficiency feature then you should take medicines and get your condition reviewed. The ulcer might take some time to heal. Stress can also cause ulcer. Please be relaxed and take medicine and observe for healing changes in the ulcer. If the ulcer remains unchanged over a month then your doctor might refer you to a specialist for evaluation and diagnosis. Please do not worry.
