Hi, sunday night my back started itching... then monday I realized I had some sort of rash in my back. A bit in the lower region and on the sides near back ribcage and near neck. Not all red but more like like bumps in my skin... Also my back feels like it's on fire... I had sex with a prostitute not too long ago but used condoms but I read that this could be a sign of HIV. I have herpes so this really made me scared...
