I have got white patches on my tongue from last three months; consulted ENT, a physician , took antifungal medicine, vizilac, becasoul capules. But to no avail. It is not giving much problem , I feel chilly if the food contains chilly. I am a teetotaler, vegetarian, no eggs, no fish. Do not eat spicy food, occasionally eat out. My age is 29 I am Male. Is it something serious?
