A little history first.
In March 2010, I had insertive anal intercourse with another male (I was the insertive partner). The encounter was brief (lasting minutes) and there was no fluid exchange that I could see/no cuts or open wounds/sores on any part of my body. It was a brief in and out lasting no more than five minutes. I found out afterward he was HIV+. I went on an nPEP for one month, then 5 months after the incident I was tested for HIV with the quick (ORAquick - blood not gum-line sample) test - it was negative. Just recently I was tested again at 8 months after the incident (also with ORAquick - blood) and it was also negative.
My question is this.
Is it possible after both of these confirmed negative results to still have HIV? I am asking this because I have developed itches in the last few months (about three or so) that seem to be symptomatic of seborrheic dermatitis.
Things such as: an itchy scalp, itching eyebrows, itching eyes, itching chest, and itching hands. These itches come and go and only once did I have a rash on the right side of my right hand that went away after a few minutes when I moisturized them. Also, they tend to itch in the same places (same locations on my scalp for example).
I have never had seborrheic dermatitis in my life (as far as I can remember) and am not sure where it could be coming from aside from a possible HIV infection. However, I will admit that I am stressing over this issue (still) and have had some recent anxiety in my life (which I understand can contribute to seborrheic dermatitis).
If you feel it is not HIV related, how can I best go about figuring out where it is coming from and confirm it is not HIV related?
Thank you for your help in this matter!
