Hi, I have a rash between my bum cheeks, down my upper thighs and in the creases under my bum cheeks and between the legs. I went the obgyn and was prescribed a clotrimozole cream and an antibiotic for a bladder infection. I was also checked for all STDs and that all came out negative. I do have eczema and am wondering if this could be the culprit... I tried applying a hydrocortizone cream for about a week and a half and although the burning has subsided a bit the rash is still red and raised from the skin.
