I feel fortunate that I know what caused my problems, so at least I can fix it. The knee is suffering from a gradual injury. Twisting as I pace the floor. Turning at one end to go back the other way over and over., The foos is caused by God knows what, but I have a set of toe separators that are gradually taking care of that. I suspect capsulitis of the second toe. If I didn't laugh at it, it would drive me crazy. LOL
