That does make me feel better about the dodgy shoulder, Steve. I've watched a video that shows how I have to use either a walker or crutches and in both cases the patient is partially weight bearing on the new hip. In some ways, the bigger problem may turn out to be the fact that the second hip is also so painful that I may not be able to do the exercises as well as I should and that may slow down the rehab. We shall see. I just keep on trying. It looks like I may be able to sit the candidacy exam for my PhD before my surgery which will get one stress out of the way.
