I've had this rash in my inner thigh for a few weeks now, I don't know what it is. I've thought maybe it's a heat rash, but it still hasn't gone away. I've put vaceline, it tends to make it relax and stop the itching but after a while it starts itching again. I have like red bumps and it itches really bad. Any ideas what I could do to help it heal it or make it go away?
