I had my left hip replaced twice recently (the second time becaise my one leg was almost an inch shorter than the other (be sure our surgeon measures). Ateer the second susrgery I gradually became aware than I was totaly incontinent, had no warning that urination or bowel movement was comng, and then no experiece of the actual happening. Whan I sit or lie down I feel like I am sitting on a child's inflatable inner tube. They cheked my spine, my brain stem, my neck, via xray and mri, but o explanation. My next step is a consultatoin with my primary care doctor at Staford.
