Suggest Remedy For Cuts And Bumps In Anal And Vaginal Region

About 5 days ago I had a small cut on the area of skin between my vagina and anus. Since then it has grown to a rash and bumps and itching all over my genitals from the clitoris to my anus. Since last night quite a few more bumps have shown up. When I pee and it hits that part of the skin that has this rash and it burns very badly. When I poop, because it stretches the skin it hurts somewhat as well. I would just like to know what you might think it is. I used neosporin which did not really help the problem just kept it the same. I started using an A and D oitment and it has helped with the pain a little, but it seems to be spreading it everywhere instead.
