Can you explain your personal symptoms, experiences, and how you happened upon discovering your condition? What made you go to the doctor and get diagnosed? I really dislike looking up medical conditions online.
Whenenver I see someone mention it now I try to preach the physio gospel because when I was going through it there were a lot of negative sufferers posting to message boards saying it will never go away, etc.
Also women can suffer from a similar condition - chronic non bacterial urinary tract infections, and most of the pelvic floor physiotherapists are used to dealing with women. Maybe it is more common in women or the option is less known for men, or maybe men are more embarrassed to go see them.
As fugoogs mentions, non-bacterial chronic prostatitis isn't well understood and there isn't an effective standard treatment protocol. There are theories ranging from it being caused by nano-bacteria that do not show up in normal tests to it being a muscular tension issue that can be resolved with physical therapy.
