I've had pelvic floor problems on and off for three years now . Seems to start when I wake up with tightness below the buttocks and rectum discomfort . Urinating can be normal or excessive but not during the night . I wondered about PN but sitting is not an issue. Definitely worse with stress. Physio has not helped . Urinating first thing in the morning can cause abdominal pain. Had all the tests and all negative. I'm 60 , slim and fit.
Which tests have you had?
