Msimon,
The bladder issues you mention raise a flag for me. I always have to strain somewhat to empty my bladder completely.
I am guessing this is because of my constantly overtight pelvic floor.
Being male, I have also seen a urologist to rule out any issues with my prostate as well.
While I am waiting to see my pain specialist I have been seeing another doctor who has been treating me with trigger point injections. He is performing these injections through my buttock to target the spasmed muscles.
I must say I have been getting some positive results with more breaks in the pain cycle rather than the usual 24/7 burning. I am getting these done each week so I hope things continue to keep improving. I notice a difference because usually mid afternoon I need to have a rest, whereas lately I have been able to keep going.
