Is there a differential diagnosis
for genital herpes that someone can do at home?
Just for those cases where it's clearly not obviously herpes, with classic oozing sores, prodromes, etc.
For example, I have a patch of skin about the size of my thumb that's red and sore, on the shaft near the glans. Been there a week. I thought it was poison ivy due to the way it felt (patchy, itchy mild bumps in a line, irritated, slight oozing from the skin), but it wasn't that bad.
