One of my friends having some problem in mouth. 2 white patches are there on her tongue. One with 2 c.m. diameter and one with .5 c.m. diameter. There was also a spot in inner cheek wall. We consulted a doctor here in Apollo(skin specialist). As per him it is due to lack of blood circulation. He gave some medicine and a gel to use. After using that the spot in the inner cheek wall got almost cured. But there is no progress for the spots on tongue. The doctor prescribe antioxidant capsules and said it will take some months get cured. Earlier, there was no sensation on those spots but now it burns if she eats spicy food. The doctor assured multiple times that it is not a cancer. Can you please suggest how long it will take to get cured? Many thanks in advance.
