My PM doctor is recommending a sympathetic nerve block (or blocks?) for my CRPS. I have browsed posts on this site and seen everything from it cured my life to it made it worse so I'm asking for more updated information since it's been some time since others posted. If you've had one 1) what can I expect (Can I really go back to work that afternoon?? How long does it take? Did you get sedated? Does it hurt? How was your recovery?) 2) did it help or make things worse? and 3) would you do it again. Thanks in advance!!
