What's the difference between GH and herpes? I was at my dermatologist a while back with a small rash on the forearm. He just casually said it was herpes and prescribed a cream for it. When I asked about it he said it is carried by most men and can be easily brought on by stress and anxiety. Since I was REALLY stressing about the move back to the US I figured, and he did too, that that was it. I used the cream and it went away. He did say not to engage in sex while it was present however. I've only seen it once since then but much smaller and now I can't say that was actually it again.
