I am 35 year old male. I had sex with a female colleague on 12 October. Not 4 hours after, I started feeling like I caught something. My symptoms included: headache, muscle pains, fever, fatigue,. This was most serious on October 14 for I was unable to go to work. I consulted a doctor friend for help. After all my fears he asked that I take HIV test. Of course he knew it would come out negative. Still I fret. I asked for PEP. He concluded that he could get me PEP for free if I could convince the lady to get tested in the 72 hour PEP window and find She's positive. That I couldn't get done and I couldn't afford to pay for it myself. Now, I feel some pain on my right chest. I've tried researching online but It's starting to get confusing. PLEASE could I have gotten infected with HIV and the symptoms, could they indicate HIV infection. I'm planning going for another HIV test once It's 3 months.
Also the chance your partner had HIV is probably zero for all practical purposes, unless you know she is an injection drug user, sex worker, etc.
Taking PEP could be a big mistake and no expert would recommend it in this circumstance. In case you're not aware, one of its downsides is that it may delay the time to a definitive HIV test. Instead of being at risk for worry until ~4 weeks after the exposure, it will mean at least 3 months and maybe 6 months of uncertainty.
