I realize you are not a doctor, though I am on the move right now and won't be able to see a dermatologist until next month.
My girlfriend thought the strange rash that she has had since her childhood (before she was sexual active) was not contagious, and therefore failed to mention it to me. This rash presides in her nether regions, and was passed along to me. She said she had it checked out when she was little, though with inconclusive results. It now comes and goes and she pays little attention to it, though it does on occasion bother her.
It originally made itself present in a few places along my pubic region and up towards my stomach. I had it checked out by the university health center, and they too were unsure. They swabbed it and it came back negative for herpes. It then went away, then about a week later one spot appeared next to my belly button. That then went away, and it showed up in one armpit. That then went away, and it came back again in the same armpit. It went away once more, and has since reappeared in the same spot. Apparently this virus likes my armpit.
The rash itself appears as one, or two, or a few red spots. They on occasion though rarely fill with puss, though always blister and leave a sore open wound. It is rather uncomfortable and a bit painful.
Pictures of the current rash can be found here
Might you have any idea what this is? Is there anything you suggest I do to minimize the discomfort?
