Hi, glad you found this site, wish it wasn't necessary, but it has proven to be a lifesaver for me.
From what my pain mgt. Dr. tells me (she's in remission from CRPS). She says IF I needed surgery she would give me a nerve block proceedure both immediately before and after in attempt to prevent spread or flare up.
Did they advise you to take 500-1000 mg Vitamin C to help prevent spread?
Anyway lots of great support and advice here.
