Hello, About a year and a half ago to two years ago, I had a swollen left testicle, with tenderness/pain, brown semen, and a pretty intense fever. I also had a uti. I went and got tested for chlamydia and gonorrhea (which came back negative), had a Rocephin shot and got put on doxycycline for ten days. The symptoms went away and haven t been back since. I need to know what it could have possibly been because there is concern that it could have been an sti in a current relationship, and that is causing some problems. Thanks You.
