Hi Debbie,
I had 3 blocks done for my right side and they all worked. I can't remember being sore, just talked like Donald Duck for about 12 hours. When I had my surgeries I had blocks done for them and they all kept it from coming back out.

What I was wondering if the RSD is in both arms or hands or is it mirroring over to the opposite side. Mine mirrors over to the left side at times.

I would have them on the worst side. Even though at this time the pain is not at it's worst try and think about which side is worse.
