Chafed and Burned Skin

[bfit]

I have a ridiculous skin problem that is preventing me from exercising. About 3 weeks ago I chafed the area between my butt cheeks (including the "perianal" area) with a wetsuit that I wore for swimming. It was red like a sunburn. About the time that it started to heal up I got a yeast infection in that area and applied anti yeast medication for about a week that inflamed the chafed skin. Now the yeast infection is gone but the skin in the area where I sit is red and painful. The doctor said I just need to "rest the skin" and not to put anything on it except for Vaseline - not even any soap. There is literally no exercise I can do that does not make my butt hurt. Has anyone else experienced this? And how long does it take to heal? I feel stupid just laying around the house because of sore butt skin.
