Hi, about six months ago I begin to experience a pain in my groin almost like I had torn something or pulled something. The pain then decended into my testicles and then went back up to my groin. It is also accompanied by a very infrequent burning in the tip of my penis when I urinate or ejaculate. It also makes me feel like my bladder is never truly empty. Help please. I have been tested for clamydhia as well as gonorhea and it came back negative. I'm very frustrated. Please help.
