A week ago while chewing the food, my inner lips got bitten by the teeth which results in a small bluish bubble(pimple). After 2 days again that bubble got bitten by teeth while having food and small amount of blood came. I later searched that such bubbled thing was called mucous cyst. Now again, a large mucous cyst has occurred and i fear that while having food it should not get destroyed! I need some medicine or other remedy to cure this mucous cyst and want to avoid in future.
