I had protected oral and vaginal sex with a hooker and it's been about a month since. About 4 days ago I started to develope hives on my arm. They came out one night and were gone by the morning. One day I had two small hives on my arm during the day and I scratched and one of them became bigger. Now they both went down but one looks like it is a rash now. It looks as big as a nickel and colored like a hickey. Can this be an HIV rash? I'm very scared. It looked like it was fading today and now I look at it it looks abit bigger and a bit darker. I did get tested for clamydia and ghonorrea and both negative. I'm very very scared now because I have never had a rash like this. What are my chances of have gotten HIV?
I have read many things online that say rashes indicate HIV, if I wasn't in any danger, what can it be?it was fading away yesterday, and over night it became darker.
