I am a guy and I started to develop all these symptoms for over 3 weeks already. I am worried about hiv since i developed all these symptoms shortly after a low risk encounter with a sex worker, but i was told it couldn't have been hiv and there's nothing to worry about it. However I keep having this sensation of heat around my body/skin randomly during the day (arms, legs, head, neck, back, face etc), it was similar to hot flash i think but I didn't sweat at all, and when i measure my body temperature orally it was normal. I also have this sensation of lump in my throat, on and off for over 3 weeks too. Sometimes it feels better (especially in the morning, after exercise, when eating something etc) but sometimes it got worse (like having a sensation of throat getting tight, swelling out and something inside). They just come and go at different times of the day.
My mouth often feels dry and thirsty, and my tongue appears to be white on the surface too, and I have a low sex drive all this time. I also have swollen lymph nodes on the side of my neck so it must be infection i suppose? I don't know what's wrong with me. Please help.
