Ok, what I think I am hearing is that your doc did nerve blocks before your TOS surgery?
That is great !!!!
It should keep the RSD at bay and help prevent spread.
I had a lumbar block prior to my knee surgery and my knee is RSD free- pain free another story
Are they wanting to do more ?
Does someone other than yourself think you are in sympathetic overdrive?
How long post op are you ?

If you would like to PM me on this please do.
I had ribresections on both sides so I am, quite familiar with this territoty.

Best of luck
try to relax a little ...
