Hi, I have a rash between my butt. It does not itch but I feel a slight burning sensation. It started out with just the slight burning sensation then i was out all day yesterday and did not wear underwear as I wanted it to breath. I was in very hot weather outside for hours. Came home and noticed a rash that wasn’t there earlier that day. I went and bought cortizone this morning and applied it. Waiting to see what happends. Would like any feedback you can give me as to what this might be.
