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..
