Ah Pauline... tough week. I'm sorry for your pain. It's bad enough to have to deal with the knee pain but when all the aches and pains start up from having to sleep certain ways, move in ways we aren't used to moving in, etc., it seems to just put us over the top of our patience limit! I know for me it does! My low back has horrid days and ok days.. but since I have taken to sleeping without elevation, my back has gotten better. But that is not for everyone, it's just what is working for me. I wish you better days ahead for sure.
