No problem. I am not going through all of this to blow the post op. end of it. My brother just ordered me a new weight bearing break rollator today as mine is down right dangerous. Its only ten years old with no breaks. Medicare won't pay for it in spite of the fact that the arthritis in my hands makes hand breaks hard to use at best. It also automaticly "catches" me when I fall forward. Once I start buzzing, I will be able to stand upright and start walking again. I will even be able to wear real shoes again. It's been at least ten years. I am putting my case manager to work on the problem of finding someone to help with surgical site care. Have a great day.
