Dear Ann,
I am so sorry for what you have been going through.
I cannot give medical advice, but I would urge you to consider finally, at long last, PROPERLY exercising your PC (kegel) muscle.
Based on your condition you should probably get a doctor's clearance to use the Kegelmaster (DO NOT ASK A SURGEON!)
One of the PC muscle's function (the muscle that the Kegelmaster addresses) is to support the bladder, uterus and rectum.
It makes sense that it can help you to avoid this horrible series of surgeries that eventually are going to ravage your body-but again this is only an opinion - not a medical claim!
Ann, you have my best wishes!
With warm regards,
Sari
