Thanks Don for replying! And yes PT and exercise IS so important and helpful. But my issue is a deteriorating disease that it atrophying my muscles regardless. RA can lead to this Cachaxia, and mine is made worse by steroid wasting syndrome - I am looking for others experiencing this. Hard to know what to expect. I have already lost most of both shoulder (cuff) and two of 3 glutes - only have Maximus working - no swimming for me! But pool water resistance is good. And chair yoga, walking ( with walker now). Any one???
