I m 21 year-old guy (homosexual) I had an unprotected sex with a man. From that time I was always thinking and worrying of having infected with HIV. Two weeks later after exposure, I had low-grade fevers (or actually feeling feverish) for 4 weeks with muscle pain, stomach cramps, little nausea, white hairy tongue. Could I have been infected with HIV? Can anxiety and worrying cause these symptoms? Thanks in advance.
