About 2 weeks ago i hade protected sex with a sex worker. About 1 week ago i started to get a small rash on my testicle. Since then ive had numerous red rashes/ bumps in various places including my scalp, hand, inside my ear, in my bellybutton. Some have already disapeared . The ones on my scalp have been itchy. Ive also had a dull pain in my right testicle which sometimes spread to my lymph node in my crotch. It also sometimes spreads to the left side, but not often. I can only imagin herpes? Possible some sort of bug biting my scalp aswell???
