Just in case you haven't ran across it yet....don't ice it.

Of course after surgeries, icing it is always recommended. BUT DON"T DO IT. From what I've read, it can make things much worse with CRPS. After my son's surgery, they kept telling him to ice it when he couldn't get the pain under control (this was before diagnosis). He wouldn't do it for three months b/c he couldn't tolerate the cold or the weight of the ice pack. Finally, three months post surgery, he started icing it - and it felt better temporarily - but his pain overall became so much worse.
