hi,
i would be careful about doing the exercises without first finding out why you have the pain and urinary dysfunction.
The change in bladder/bowel habits or any change in sensation in that area are called "red flags" - that means there *might* be something seriously wrong.
The immediate action i take with my patients who present to me like this is to send them off to the doctor immediately (i ring the doctor or the hospital).
Then, once everything has been clarified, i would then decide treatment options, of which specific exercises would be part of the total solution.
Hope that helps!
