I am very sorry to hear that your RSD has spread...but with proper treatment early on you can hopefully maintain full function and use of your hands. My RSD spread from my left ankle to my entire upper body, including both arms and hands. I have the pain of course but I think it could have been much worse than it is and I believe this is in large part because of agressive therapy. Except for really bad flares when the swelling is too bad...I have full use of my hands...something for which I am incredibly thankful. Hang in there and keep us posted on how things go.
