thanks again I do not understand what the TENS unit is. Is it a trainer for pelvic floor muscle rehab ( Kegels) ?
I am trying to get my own biofeedback handheld device the one I will likely get has an internal sensor (rectal probe) which my pt says is much better than electrodes on the skin. I know it is a lot of money but if it can help me get better sooner.

did you need to get the partial nerve sparing because the cancer was also outside of the prostrate?? thanks very much
