Ok, so I had chlamydia once about 5 years ago, got treated and everything was good. I had an OOPS! about a month ago, (unprotected sex with a girl) and noticed some pain urinating, pain at the tip of my penis and now clear discharge. I went to the doctor and without testing, he gave my all three antiobiotics to treat chlamydia/ngu, gonorrhea and trich. In office they gave me one injection of Rocephin, and a prescription for Doxycycline and Flagyl.
