Called my clinic this afternoon to see if they could look at my knee. They are supposed to have x-ray capability there. It's now 1642, and so far no response. If I don't hear from them by 5, I'll hobble around and try a bit more casting. As slow as I'm moving, it'll take me an hour to get everything set up! I've found that if I bend forward at the waist at about a 45degree angle, and keep my knees slightly bent, I can motivate with relative ease and only minor discomfort. Can't do that for long, as the arthritis in my lower back starts to complain after a while. It likes me to stand straight. Oh, well, shuffling on......
