a few months ago I developed severe pain while walking at work. I look in the mirror and the surrounding area of my buttcrack looks like it has a rash. It's not red, but it's darker than my skin and looks dirty-ish. Whenever I'm at work I pray that I don't have any pain. It seems as if the first 4 hours of walking i am fine but then that's when the pain comes in. After that whenever I'm walking I feel unbearable pain down at the bottom of my buttcrack. I have found a solution in wearing shorts under my work pants, but the rash still won't go away. Can anyone help?
