I have to admit that physiotherapy - or what I was able to receive of it - didn't help me very much, either. One odd thing was that on my final visit my physio showed me a whole array of dilation devices which she said the CRS recommended - but she was unable to prescribe any of them for me because they were used by a different clinic than the one I was enrolled in. She also said that in her opinion, based on what I had told her about the pain I'd experienced during digital examinations, dilation would be too painful for me. I also got the impression that there were two separate lines of treatment in this clinic - one for female patients and one for male patients. Also, age limits came into play, as far as I could see - and at 73, most therapies apart from PT exercises and stool softeners were more or less ruled out for me.
The whole area of colorectal and pelvic disorders (AF, PFD, CPPS, etc) seems rather hazy and ill-defined (for men there is a peculiar overlap with prostatitis). There don't appear to be any sure-fire cures for them, and beyond stool softeners, creams and ointments, physical exercises and pain management, clinicians and surgeons are divided about what constitutes appropriate treatment. In the UK there are a growing number of private, independent clinics - one example is the male-only London Pelvic Pain Clinic (
https://www.thepelvicpainclinic.co.uk) - that offer physiotherapy-based and 'biopsychosocial' treatments for pelvic pain and discomfort. But it's hard to know how effective these treatments really are. My NHS physiotherapist was unable to advise me.
