Well, I got the results from the doctor last night. First it isn't arthritis in my knee. He now thinks I might have cartilage or ligament damage so he is trying to book a MRI. He expects the wait to be about six weeks. Then he told me that my potassium is very low and wants me to start taking a supplement. At least, it all seems fixable. So I really need to get out and do more walking even if it is slow. We are going to the trailer for the weekend. So Bill will help by pushing for some walks around the park. We are fortunate as we are in a nice and senic area
