Catra, I don't think I've ever heard of anyone claiming Ketamine causing spread? Have you had an IV post RSD?

Sandy, Regarding acupuncture, I kind of have mixed feelings. I did try it several years ago. It did provide temporary relief, and the needles were not that big of a deal... You might want to consider accupressure, as well.

I don't believe you mentioned undergoing sympathetic blocks? That's usually the first procedure tried. If you're interested, I'll go into a lengthy explanation... I know not everyone is a fan, but I do believe they put some into remission if done within the 1st year (and the earlier, the more effective) and the technique and meds make a difference as well.
