I have had a rash for 2 months and it hasn't went away. I went to 2 doctors the 1st doctor said its just a rash, and it didn't look serious the other doctor said," It looks like a fungus rash" The kind that diabetic's get . Its like a reddish/purplish color not bigger than a quarter and it doesn't itch. I used some equate rash crème and fungi crème on it and its still there. It was a little bit bigger than it is now but I'm worried...
