It was all start with a sharp pain after once I ejaculated about 4 months ago, the pain didn't go away for the whole night. On the very next day I felt pain in my pelvis and back, not very bad but still were annoying. I've been prescribed with 4 different types of antibiotics and anti-microbiles, none of them has ever worked on clearing up the pain. 
I was told by the doctors that I might have nonbacterial prostatitis cause no bacterial was found in my tests and it cannot be cured. What's your view on this? Will the herbal diuretic pills work on it?
