I had a drunken, unprotected encounter on 1st of November with a girl that I know from a long time. A few days later I developed STD symptoms and tested positive for chlamydia. I informed her and she freaked out, so she tested for everything, including HIV and it all came back negative (except chlamydia of course). She hadn't had unprotected intercourse 6 months before me. I wouldn't be worried about HIV but on 23th of December I developed high fever (between 37,8 and 38,5 C) without any other symptoms and the next day I had something like rash. I went to a doctor and he said that's it's definitely Chickenpox, although unusual at my age (I am 32), but I haven't had chickenpox as a child. Please tell me could this also be a sign of HIV?
