About a week ago I was experiencing a frequent itching around my vagina and on it. It wasn't a constant itch, just occasional. I thought nothing of it until after showering I notices how dry the skin outside of my vagina looked, and this strange almost purpleless discoloration on my thighs. I rewashed the areas and after getting a better look, I saw that the discoloration was in a patch at the top of my vagina as well. It is a circular brownish rash. This part doesn't itch, Except for the part on my thighs. I'm not sure if I've been scratching In my sleep, but there is also reddish sores on my thighs that itch, but I think could be contagious becuase a sore has appeared on my stomach this morning. Please help. I haven't had any sexual contact, and I've never had sores like this.
