Ok, so two weeks ago I tested positive for gonorrhea and received a shot of Rocephin to get rid of the infection. At the time of the test, I had a milky white discharge from my penis. Almost immediately after the shot, the discharge became clear and I had a lot less. However, it has been exactly two weeks since the injection and I still have a small amount of clear discharge from my penis. Is this normal? Do I need to go back in?
