I've had this.... going on 7 years now. At least I've been told it is Epididymitis and/or prostatitus depending on which doctor you see on which visit.
The very first time I went to the urologist, he said, "This can be cronic..."
He was right. My pain never goes away!
I've had ultrasounds, CT scans (I think it was). I've had a procedure done
twice where they open up my penis so that my urine stream will flow better. They suspected that my bladder wasn't being emptied completely and it was causing infections. Two different urologist performed this procedure on me. (I forget the name)
I've provided multiple seman specimens for lab work etc...
I've seen four different urolgist in 3 cities over a span of 6-7 years because my pain never goes away.
It feels like someone just racked me in the nuts... but not too hard because I can endure the pain. It is just a 'discomfort' most of the time.
The last urologist said that I'm not infected but just experience pain in my nuts and lower abdomen.
He said it is like a migrain headache. No cause. No cure. Just take some asprine to help my blood flow better and sit in a warm tub of water often.
I can deal with the pain. But after taking anitbiotics so often, and having it releave the symptoms, I'm a little concerned that I do have a constant infection. I just wonder what a constant infection will do to your body.
At this point... I've just given up seeing doctors until/unless the pain gets so bad I have no choice but to go back.
