I had unprotected sex with a man about 3-4 weeks ago withput knowing precum can spread hiv infection. I haven't shown any signs except now i have skin bumps. they are on my right hand on the top, wrist and arm. they don't itch and they look slightly white. Does this sound like hiv rash? i have also started a mee dish washing job in the last three days so it may be a reaction to that. But i would like to be sure. if you need more information just ask. also another note is that the bumps are only on hair folicals on my arm.
