hi gigi. i have had rsd (that started in my right wrist after accidentally breaking it) for almost five years and had eight nb done during the first year (one a week) in my neck. it helped a bit with the swelling and other symptoms but not alot. but everyone reacts differently and maybe it will help you more. it's of course has to be your decision. if i were you i would get several opinions on it from a pm dr and neurologist and gp. i was anesthetized when i had mine done because i couldn't handle being awake for a needle in my neck. but everyone can handle things differently too. i'm not a dr so check with them but if you do get it done, i hope it helps ease your rsd pain. soft hugs.
