hi. I have a question. I had unprotected sex in september 2009. I tested negative with the oral rapid swab test for hiv, 19 weeks after incedent. My problem is that I still occasionally have what feels like a low grade fever, like my face is flushed. And occasional muscle pain. And this is now 20 months later. The girl i was with said she is clean and tested negative around the same time i did. My question is can I trust my test? And would you say my symptoms are from something else.? Do I need a retest or can I trust the one I had? Thanks in advance
