I'm having a problem with my anal area getting chafed and when I walk, it starts burning, and I get a little blood on the skin. Have had a colonoscopy recently and that's fine, and a digital anal exam, which was fine too. My family doctor prescribed an anti-fungal/cortisone combinatinon cream. She said it was yeast, due to an antibiotic I took. Its been 2 1/2 weeks now... shouldn't it be getting well, or is the chafing irritating it further? I'm 64 year old, and not on any hormones. Thanks!
