I have a recurring infection around my anus. It's hell. It will come on gradually over about a week, and at it's worst it makes staying clean a horrible experience. Then, after a few weeks, it clears up and I'm fine for a month or two--lather, rinse, repeat. I had a case of jock itch that had spread to that area several years ago. Based on that experience, I can tell I'm dealing with the same thing this time around. However, it doesn't respond to Lotrimin Ultra the way it did the first time. I'm so horribly embarrassed to be examined by a physician, and I've been suffering with this for a couple years now.
