I had unprotected receptive vaginal sex for 20 seconds while I was on the last few days of my period with someone i didn't know very well. This is what I do know; He is 22, a crack user, said he injected heroin once with a clean needle, and he said he's had mono (whether tested for mono is unknown)

These are the most current tests that i've had done:

-. I got tested for hiv with a combo p24 antigen/antibody test at 29 days post possible exposure which was negative. -I got an 11 week and 3 day antibody test which was also negative. -hcv/hbv/syphillis test at 77 days post exposure-came back negative -hcv rna test at 6.5 weeks after exposure-negative At 8 weeks post exposure I started having severe knee pain that shifts back and forth between knees. This has gone on for 4 weeks now and is still continuing. Its so bad that ive had to take ibuprofin and hot baths to relieve the pain, and I'm scheduled to see an orthopedic specialist as well as pysiotherapy. I've also had joint pain in my hands on and off. I'm scared that this may be reactive arthritis or rheumatoid arthritis due to hiv infection as I haven't had any injury. What are the chances of this being the case? I'm only 23

Can I trust a 3 month hiv antibody test? Or should i test to 6 months? Can inactivity/stress/depression cause pain to this severity?? I'm not overweight at all. I'm 5'9 and roughly 140 lbs.

Hello there- While you did have a risk exposure, I think that the tests that you had are accurate in that you are indeed HIV negative. I don't think your symptoms are related to HIV infection and agree with seeing an orthopedic dr for evaluation. If that is unproductive would consider a primary care dr or rheumatologist.
