Hello. I am 20 and sexually active. I was checked for STDs which was negative. I have several grey rashes on my vagina which itch alot. I also have a large one on my back. It has been there for about five months now, the antifungal cream reduced the itching but the more i scratch it, the more it spreads.It looks like the christmas tree rash- elliptical in shape. it is dry and greyish pink. i also have one on the back of my thigh and buttock which looks like thin swollen cuts or welts. they itch and i originally thought they were insect bites. Please assist me. thank you.
