Over a month ago I had diverticulitis. They gave me metronidazole and amox/k clav both 500 mg. The same night I took them my penis became red and very irritated. The next morning the skin of my penis was peeling and bleeding. I went to the emergency room 4 times in 5 days to tell see what was wrong. They kept telling me that it was a part of the deal. Just to put neosporen or vasolinr on it. It has been a month and it still hurts. I m scared it will get infected and fall off. What is wrong?
