My advice for you is to talk to your Dr. and when you get in the hospital for the surgery talk to the Anesteologist about a block.

The 4 surgeries that I had blocks before, the RSD didnot spread. I had a rotator cuff surgery, ulner nerve, 3 inches of muscle removed under my left arm for TOS and triggerfinger surgery. All 4 times the Dr. agreed that blocks were needed and the Anesteologist are so great about doing them. They know what they are doing. I was already asleep when they did the blocks so I didn't feel them.

Hope this helps and I hope your surgery goes well.
