I had my gall bladder out last year. The tube did not form the bag from like most people do or it s still in the making. Anyway, I get diarrhea sometimes due to eating greasy foods. I stay away from them as much as possible now, but when I get diarrhea my skin around the anus becomes raw and bleeds. It s very sore and bloody but it s not piles or hemorrhoids. What can I buy over the counter to heal the skin and relieve the burning? .
