I saw a clinic who prescribed zithromax, although my chlamydia/gono test came
back negative. A couple days later I noticed that I had red
bumps on my the
head of my penis, only when it is erect. Nothing is noticeable when it is flacid. I saw a urologist and showed him pictures of the erect penis, but he did no testing. He said he didn't think I was contagious and thinks its a reaction to the zithromax, and that it would probably clear up in a few months. Does this sound right?
