High dosage of Vit C is a good idea as well. I;m sure Littlepaw will remember the specifics... hint, hint, I'm to tired to hunt.

I'm a fan of Epson Salt lotion--it works well on swelling for me. If you respond well to steroids, I'd request possibly taking a course post op. Have Lidocaine patches on hand to help calm things down.

I did undergo surgery in my original CRPS site, 3 or 4 years after developing it. I had a stellate ganglion block by a former spine surgery that was amazing at blocks (I've had them done by 3 docs at this point and there is a VAST difference in outcome depending on the docs technique and attention to precision.) I had no complications from that surgery whatsoever. He also made sure to be very gentle with my limb and didn't use a tourniquet (I'm not sure if they're used in lower limb surgeries ever?)
