Q: I bit my lower lip several times while eating which has led to the formation of a small bubble like blister. Could you suggest a medicine?

A:Since you mention that it is like a blister I have to assume that it is filled with a clear fluid and that there is no infection (redness or a pus-like discharge or fever). No treatment is necessary. The lesion should resolve on its own in a matter of a few days. If you do have signs of infection as indicated above, you should see your physician.
