About 15 days ago I was in vacation in Japan and had unprotected sex with a lady while I was drunk. She later told me that she used to be addicted to heroin, which freaked me out! (high risk)
Now, I have a friend who is in the medical field, and I was scared, and they basically gave me the "rape kit". I took some pills, got a shot in the butt, and got a 7 day prescription of doxycycline (the standard cure meds for the clap, etc). I hoped that would take care of anything, if I had something.
I've had outrageous diarrehia for like 5 days. It was so bad that I developed a rash on my butt and a hemmeroid. Now, it seems the diarrehia is gone, but now for the last 2 days my groin lymph nodes have been painful, and I think swollen.
I have no other symptoms (no fever, etc). Do I have HIV? What is the risk of one time unprotected sex of getting it? I am so scared I'm damn near suicidal here! Please help!
