I have a quarter size rash on my calf that has been there for about a month now. I put neosporine on it to help it heal but it is completely unchanged from the first time I noticed. It doesnt itch or hurt at all. I wouldnt even know that it is there aside from the coloring. It is not ringworm, I know what that looks like. The area is slightly bumpy, but only very slightly and is a splotchy red color. Please help. Thank you!
