I just want to add that I have fired my primary Doctor for insensitive remarks and when I found a new one I called to have my records moved and told them exactly why I was leaving. I also have had knee shots for years before I finally had to have new knees and what a relief it is to be able to walk pain free. I have put on a great deal of weight from inactivity due to pain. Not good but it happens. Good luck to you. Jan
