I have a circular rash/sore on my scrotum. It is red, inflamed, itchy. Not breaking the skin. Came on over the course of 4 days, starting as tight skin in the area, then becoming itchy, then red and sore. I do have HIV and herpes though my herpes outbreaks are confined to my butt cheek. Im on Cymbalta, Reyataz and Epzicom, and Valtrex for the herpes.
