I had sex with another man, both anal and oral, anal was with a condom and there was no breakage or spillage of semen inside of me. He also gave me oral and swallowed and also rimmed me. I tested at 8-weeks and was negative, a few weeks later I got a rash starting at my underarm, it spread toward my elbows. Some of the rash is like a pink welt, others look like mosquito bites and they do itch. I have had a rash similar to this in the past and was given a corticortisone cream for it, seems like it went away sooner the other times. I have had this rash for about 3-weeks, it seems to go away in one place and reoccur in another place on my arm. I have talked to the health department, they seem to think if that is the only place I have the rash that it is some kind of contact rash, and since it hasn't appeared on my neck, back, chest or anywhere else they feel it isn't an std. I'm just looking for another opinion, they don't feel I need retested.
