Is it true that chest tightness is NOT a sign of ARS? I ask bcuz if had a low risk situation back in march. During the week that jus passed I experienced chest tightness that lasted 2-3 days then disappeared. After that I noticed a small bump on my arm a couple inches above my wrist resembling a bug bite. I've read Internet info that states sometimes ppl have HIV related bumps that they mistake for bug bites
