This all started when I messed around with a girl that I found out after to have been very permiscuous. I have been stressed for the last 5 and 1/2 months about HIV and STDS. I tested negative at 3 months for all, 4 months and 5 months for HIV. Since then I have allergies come about worse than before, tested by an allergist and was told I am very allergic to alot of things. My skin now on my stomach feels like its prickly, itchy, and burns. I don't know what to do and whenever I put a shirt on now my stomach prickles and itches alot.
