Went to the Doctor today and discovered that I probably have bursitis, which is an inflamation of the lubrication sacks around my knee. We have no idea why it happened, but I am going to start on a perscription anti-inflammitory and see if it helps. I sure hope so. Last night I cried for much of the night. While I freely admit I am a wimp, I was surprised by the intensity of the pain.
I am greatly relieved that the Doc doesn't think I damaged anything. I was very concerned about having done some kind of structural damage. At this point, he doesn't think so.
I certainly appreciate your prayers. It is a very different world when you can't walk.
