I have a red rash around my anus. I am also experiencing vaginal itching and burning and have a white mucousy material in my vaginal region. The rash is almost like a raised ring around my anus. It's a little sore to walk. It feels raw and moist and there aren't any bumps. Just red and sore.I have been running a lot recently and usually come home to do house work and run errands before I shower. I also took some antibiotics a few months ago for strep throat. Could this be from a yeast infection or something worse?
