I have an itchy red bump on my back that has appeared there about once every year for that past 10 years. It gets about 5 small clusters of bumps on the red spot and gets very itchy after the first couple days it appears. It also becomes alittle painful, and after a few days it gets scabby and goes away. I was told by a doctor awhile ago that it could be a type of skin herpes (on my back though?). If anyone has any ideas of what it is I'd love to hear them.
