Hello doctor,I have a brief sex encounter with a sex worker, 3 nights ago, We had protected sex, no anal, but vaginal sex (protected), no licking on clitoris and she performed oral sex with condom on. We had some light kisses no tongue.I have not experienced fever, swollen glands, but today I felt very tired and dizzy, thats why i checked the HIV symptoms online and found out that fatigue is one of the early HIV signs. I am really worried, and want your assessment on my HIV risk, also I would like to note that I have a minor heart problem, abnormal heart beat in few occasions. and I work 9 hours a day but I never as tired as today.
