I am a teenager, and for around three days now I have had a large red and slightly raised rash between my bum cheeks and all the way down to my vagina. It is inflamed and uncomfortable. I have tried Sudocrem but it has not made any improvements to it at all. There is a small cut that sometimes bleeds a little just to the right of my perineum, and a couple of very small ones just above my clitoris. I have had a little rash in the same place a few times before but I haven't had to do anything to it and it has gone in a couple of days. But this is very different and worse by far.
If anyone could tell me what this might be, the causes and what I could do about it I would be very thankful.
