This may come as a shock, but everyone has hemorrhoids. An over-the-counter antifungal cream can cure the infection on the skin, or your doctor can prescribe an oral medication to kill the yeast on the skin and balance the yeast in the bowels. The fix: To treat a fungal infection on the butt and ease itching, the first step is to keep the area clean and dry since fungi love warm, dark, moist environments, says Dr.

If it's fungus that has spread from elsewhere (which can happen by touching an infected area and then touching your backside), you'll usually see signs of it in the form of athlete's foot or toenail fungus, and it will manifest itself in a dry, itchy, scaly rash that can affect both the buttocks and the anus, explains Dr.

The yeast-type infection usually only shows up around the anus, and in addition to being extremely itchy, you may notice redness and pimple-like bumps. A fungal infection on the butt generally comes from two possibilities: an overgrowth of the yeast that's normally found in the bowels and on the perianal skin (aka the skin immediately surrounding the anus), or fungus that has spread along the skin from a different area of the body, says Cynthia Bailey, M.D., a board-certified dermatologist based in California.
