Hi Doctor,
I had unprotected sex (insertive vaginal) with a woman who I now know had two previous unprotected encounters. A few weeks later, I developed a red, slightly raised rash on one side of my face. It doesn't seem to be bumpy anywhere, just red, flat and raised.
It started out as a small red area, about the size of a nickel. The next day it had spread, and was now blotchy and covered most of my cheek. It felt hot and tingled slightly. The next day it had spread just behind my ear and slightly down my neck. It was now less blotchy and looked more like a few solid thick red streaks on my face. It became more and more itchy over the next few days. I eventually saw my GP who was stumped, but prescribed 1% hydrocortisone cream, which seems to have brought it down to the point where it doesn't itch and is just barely noticeable. The rash has lasted about 10 days, the last three of which it's been hardly there.
I was tested for std's, and I was treated for gonorrhea/chlamydia. This was after the rash appeared. At that point, I also had a HIV rapid-test done, which was negative. This was at about 3 weeks post-exposure. Other than the rash, I've had no ARS symptoms (fever, swollen glands, etc).
My questions are:
1. Does this rash sound like it could be HIV related? I know with only one exposure, the odds are in my favor. I've heard that the rash is usually more on the trunk as well as the face and neck, is not unilateral, and isn't itchy..but I've also read that it can be.
2. If it were an ARS related rash, would it respond to hydrocortisone?
3. How likely is it to have acute HIV and have a rash as the only symptom? Do the rash and fever usually go hand-in-hand, or is it possible to only have the rash?
4. I know 3 months is the ideal time for rapid testing. However, I've also read that if symptoms are present, it's likely to test positive. If indeed the rash was HIV related, would it have shown up in the test, or is it still too soon after the exposure?
Thanks
