Hi. My name is Hillary. I am 19 years old. About two years ago, there appeared to be a small white patch on my bottom lip. Since then, I have just been biting it. I have deeply bitten that area several times. The patch went away in a couple of days but since I bit that part of my lip several times, I feel a lump (I do not smoke. I have never smoked). It is not noticeable though, it does not hurt or itch. Till this day I feel that lump. I have been going to a dermatologist for this problem but all he does is prescribe ointments. What can I do to get rid of it? How long will it take until I get cured?
