Hi Ada,
I understand what you mean when you said no matter what you try you end up worse. I went that route for a long time. Before the RSD, I ran or walked 2 to 5 miles a day, did aerobics (taught for awhile) and did weights. Needless to say, I was in really good shape. When I first got RSD, it was only in the hand and I could still exercise. Then it went to the legs. Talk about life changing. Anyways, I tried the water PT and it worked for awhile. I was also given exercise to do to strengthen the legs. I can't get on the floor (since I can't get up from it) so I got a doctor's exam table (and shortened a bit) and do the exercises on that. The exercises were starting to cause more pain so I took a rest for a month and found out that now if I onlydo them every other day rather than every day, I am fine. We are all different and I hope you can find what works for you. My experience has been that I just can't push it now.
