Doctor I have hard muscle pain all over my body in leg bellies in back in arms I alsp had unprotected male to male sex. I got my partners hiv test that came out negative. But I am unaware whether he was in his window period or not. After one month I had mine duo 4 gen test. That came out negative. And after 93 days of exposure. I had mine antibody test. That too came out negative is this HIV which is causing these pain please tell doctor.
