I don't know what is going on. I have around 25 or 30 small pimple-like sores on my right hand and they kind of sting, itch, and hurt. They are very small and develop a head on them filled with puss. I want to believe it is an allergic reaction to something but I am not so sure. I can't think of anything I may have some in contact with that would cause such a reaction, except....I was intimate with a woman about a week ago, only using my fingers on her (yes, using the right hand that now has the sores) and 3 days later I had this outbreak. It doesn't look like pictures of herpes but again, I don't know. There was a lot of fluid transfer from her to my hand. Could this be some sort of STD? Could it be an allergic reaction to her fluid or the washing that I did afterward? It seems like too much of a coincidence that I would have this encounter and then develop this "rash". HELP!!!
