This is really for my own education; you guys are way over my head with a good bit of this, but was prostatitis ruled out?
I dealt with it for for quite some time in my 40s, and it played hell with my PSA as well causing some unexpected/unpleasant...... umm....events. Was afraid it was going to be a chronic condition as it kept coming back. The symptoms would improve, PSA would drop. Symptoms rebounded, PSA would go back up. 
I actually had epididymitis from a groin injury ( I got popped in the cubes with a stray sledgehammer, but only the left really got the brunt of the hit) and then later on prostatitis Twas very unpleasant all around. Still blame my torn spinal erector on the multiple rounds of fluoroquinolone, but I may be wrong.
There are 3 loves in my life: my wife, my English mastiffs, and my weightlifting....Man, my wife gets really pissed when I get the 3 confused...
