Two weeks ago I had a bad case of diarrhea. Unfortunately I did not wipe good enough and my rectal area began to itch. I went to the bathroom, and wiped, to notice some fecal matter was still on my rectal area. I cleaned it and washed it pretty throughly. THen it became red and very itchy. A few days later, it appeared to "peel" and I thought it was gone. Then more redness came and the cycle started over. What is this and how do I cure it? I am thinking it may be a rectal yeast infection?
