how long can genital herpes outbreak last if untreated? I went to the doctor and was told I just have a yeast rash and they prescribed me anti fungal cream and it helped the itching but the rash is still there. It just looks raw. there are no blisters, no oozing, no bleeding.. just raw skin on the inner thigh area. I noticed this rash about in mid September. Also I’ve been using the cream for a week and a half. I’m planning on calling my doctor first thing Monday.
