Lotus boy, what was your risks?
Rash due to HIV-related ARS does not occur alone. It would be accompanied by other, serious "flu-like" symptoms, notably fever, fatigue (like when you have the flu), and lymphadenopathy.
All of the symptoms together will last from a few days to 2 weeks. They do not 'come and go'.
HIV-related ARS rash is concentrated on the upper torso, neck, and face, and tends to be non-itchy. It looks very similar to other viral rashes (e.g., measles, rubella) and to a drug-interaction rash. More rarely, it can also involve the palms and peeling skin.

Bottom line: NO symptoms are a definite indicator of HIV. However, if you are experiencing a rash that 'comes and goes' and is concentrated on your extremities (arms/legs), and you have no other symptoms of illness, you can be confident that it is not related to HIV.
Rash is also associated with secondary (2nd stage)syphilis. This would indicate a long-standing (2+ years) of infection with syphilis.

Overall, excema seems like a more likely source, based on what I could glean from your description. See your PCP or a dermatologist for proper diagnosis.
