Hi,
In a case like this I hope you have a very good wc atty as well as your own wc doctors of your choice. If not a good wc atty should have a list of good drs.

I wouldn't let them push or rush you into anything, especially a surgery.

Have you read on our RSD forum ?
There are threads on sympathectomies {spelling?}there - you can use the search tool to find them.

You might also read on our TOS forum also , in case your RSI's have evolved into TOS. many with severe TOS get RSD also.

Check thru the useful sticky threads on both forums too.
