Sue,

I hope the RSD calms down, of course the surgery hasn't helped it one bit but you are now having to undergo the consequences of surgery and RSD and I am *so* sorry because it is terrible - I know. After my knee arthroscopy (wasn't even full fledged surgery), my entire leg turned black (this purple/grey/blackish color depending on how much time I was upright). I scared every nurse in sight, and more came in to actually see for themselves, then every time I was ordered to go straight back to bed and told to not put weight on it anymore. My RSD and the pain I had worsened much faster after that.

I hope everything at the pain clinic goes well.
Take your time to recover.
