My CRPS is in both feet, my left knee, and left butt. I just rediscovered a video for exercises for people over 55 or with Parkinson's and they are all done from a chair. I did it about six days ago. Even with that it was painful and some I couldn't do as I also have been dx with Stiff Person Syndrome and anything dealing with my right shoulder area can set off contractions body wide. I am going to try again today. I know it is important to keep moving whatever one can and to delight in the fact that some days are better than others. Thanks for responding. Just as a side note - I haven't been successful in finding PTs who know how to deal with my CRPS, myofascial pain, Stiff Person Syndrome, Degenerative Disc Disease, and small fiber neuropathy.
