Agreed...it's always a balancing act with RSD in terms of movement and rest. I think you also want to pay attention to HOW you move the arm. I have two good examples, both of which are fairly recent. First, I was typing up a long email to someone (took over an hour to type it all out) and I was really into it. When I was done, I felt the worst pain in my elbow and shoulder which I hadn't really moved in that whole hour. See...my hands were moving from the wrist down but my ARM wasn't really moving. The second example was when I went fishing with my boyfriend last month. I hold the pole in my right hand and I caught over 20 fish in the first few hours we were out there (so I was obviously moving my arm) but when we decided to go in I tried to set the pole down and I found I couldn't hardly open my hand...the pain was so intense. And it was because even though I was holding the pole and using my hand...I wasn't really moving it at all. Lesson learned...I need to be careful to keep everything moving and not immobilize it. The motions a lot of times need to be fairly deliberate. I made the mistake of thinking just because I was doing things and using my hands/arms that it was enough...but it's not just that you use them...it's HOW you use them too. I go back to many of my early PT exercises because those are the ones that really focused on the deliberate movements and they can all be done when I am sitting without putting too much stress on my body and the RSD.
