Hi alan...sorry you are having problems with those knees. Kind of makes it hard to sleep, doesn't it? And going up and down stairs, yeah, it hurts. There is some good information about trying to deal with arthritis. I don't know very much about MG. So I don't know if that would make a difference in how you treat your arthritis. But, it is nice to see you here. I don't come in here everyday as I deal with other problems and visit some of the other forums. I try to make it a point to come by here every couple of days or so. I have a problem with one knee. I think it is due to an old injury. I have found that injuries can set up an arthritic process. Take care, maybe we can share some ideas.
