I had protected sex (condom, no lubricant, no breakage) with someone about a month ago. A couple weeks later i got strep throat and didn't think much of it. But then i got a bit tired and lost my appetitie so i got more worried. Went in for an HIV test (3wks after encounter) and it came back negative (Elisa-EIA)-my doc told me to stop worrying and i was fine. The strep throat went away in a few days and i felt better and i stopped worrying. Then i got a small bump on my tongue now that hurts. It's not an open sore, just one small red bump halfway on my tongue. Ordinarily, i wouldn't be very worried about each of these symptoms, but put them together, and i'm really getting worried. My question is, how sensitive is the Elisa test 3wks post encounter? Is my tongue sore typical of ARS? Can i reasonably put these symptoms to my anxiety about the situation rather than anything bad? P.S. I'm not one of those people who will keep posting excessively. Please feel free to share your knowledge, thanks so much.
