Hi, I've had a recent episode where I had protected sex with a female but not sure if the condom rolled up halfway during intercourse as she was grinding really hard. Also not sure if the condom was punctured but I suppose not. Anyhow 1 week after I've been having light headaches which has been going on for almost 2 weeks now. And I might have maculopapular rash but not sure because I had chicken pox bad as a child and the dark spots remain, but for some reason I cannot differentiate. Also slight muscle pain in my leg. Are the headaches a strong indicator of Hiv infection, I've never really had headaches last this long. Also I do not have fever or sore throat at this point. Do symptoms come all at once or one by one? The incident happened Nov 2 so about 3 weeks ago
