Hi Blue,
Thanks for the update. It is good they are being cautious and if a series of blocks takes care of it that's great! If not (even if it is CRPS) taking the staple out could potentially make a difference. I have read articles on CRPS going into remission if it was caused by an injured nerve, impingement or neuroma that was surgically addressed. I will try to post one I just read recently that was from a plastic surgery journal stating surgery should be considered in CRPS patients who were suspected of having a fixable nerve issue.
Sending hugs,
