I had receptive oral (unprotected) and insertive (protected; condom) sex (MSM). I have been have random itchy hives throughout my body and burning red spots here and there between my thighs for some time. I tested negative with at 61 days post event with the following test: 'HIV 1+2 AB+HIV1P24 AG, CLA' (blood draw) from Kaiser Perm. 

My first thought is to congratulate you on apparently consistent safe sexual practices, based on what you say now and in regard to the exposure that led to your two discussions with me and Dr. Hook a few months ago. Even if your partner had HIV, you were at virtually no risk of HIV from the events described. In addition, I'm glad to see you've had higher quality HIV testing (an antigen-antibody, i.e. AgAb or "fourth generation" blood test) rather than the Oraquick test you described earlier.

The AgAb tests, including the one you had, are among the most accurate diagnostic tests ever developed, for any medical condition. When done sufficiently long after the last possible exposure, the results overrule all other considerations: no matter how high the risk of exposure at the time, and no matter how typical the symptoms for a new HIV infection, the test result is dependable. And the time to reliable testing is not 90 days -- that's old news, going back to older tests now rarely used. With the AgAb test, the interval to conclusive testing ("window period") is 6 weeks. Your result at 61 days proves you do not have HIV (assuming you haven't been reexposed since then).

And the symptoms you describe are not at all suggestive of a new HIV infection. If they continue and/or you remain concerned, see a health professional. Mmost primary care physicians probably would be able to diagnose and manage the sort of skin problems you describe, but for definite expertise you could see a dermatologist. But in the meantime, you can dismiss HIV as a cause. You don't have it.

I hope these comments are helpful. Let me know if anything isn't clear.
