I have had a couple of bumps on my penile shaft that have last over 4 weeks now. Over this time period, and longer, I have been developing small fluid filled bumps all over my hands, in between fingers, wrists, and ankles which I think may be related. I also have small areas on both elbows and waistline which are extremely itchy. Also, there is a rash on the head of my penis that I had cultured for HSV which came back negative. Skin problems are really starting to scare me and would like an answer. Don't know if they are all related or not.
