For quite a few years I have had thick, crusty skin on my upper lip. At first it was just a little, but now it is about 1/2 an inch across and is getting below my upper lip line. I have tried several antifungal creams, lotramin, hydro cortisone, etc. I have sanded it with a clean fingernail file and have to use tweezers almost every day to get loose skin off. Any thoughts? I am 66, weigh 175. Breast cancer on each side is my only serious health history. They were each found in a yearly mamagram and were very small. I had a mastectomy with reconstruction both times. The first time, almost 14 years ago, I took Tamoxifin for 5 years. The second time, about 9 years ago, no treatment was recommended.
