Wreta,
If it helps for you to know, I had brain surgery with CRPS, but I had no choice. I would have preferred not to do it, but we don't always get choices.

Like you I have CRPS in all 4 limbs. The only reason mine is not worse is because I take LDN, I constantly exercise and I go to aqua PT. And I rest.

I found out the hard way that this is not a disease that improves becaused you pushed yourself over the edge, just the opposite you really need to rest after activity.
