Hi Bobber,
Here is a link to an article on RSDSA.org about continuous peripheral nerve blocks being used on Soldiers injured in the Iraq war.
RSDSA.org is the best resource for up to date and accurate information about RSD/CRPS.

I wish I had the opportunity to have had this done early in my diagnosis but it was too late for me.
I wish you well.
