I, too, am dealing with RSD like symptoms that I suffered with right after my failed surgery and now came up randomly after 8 years. I am trying to get doctors help to do an MRI because I don't know if it is the RSD itself or if something has changed in my neck to cause compression.. How can I tell??
Good luck to you and I wish you all the best! Attend conferences thru the Chiari orgs. and be informed.. NEVER have surgery unless you have done a lot of research and are fully confident in your doctors knowledge of this condition.. Believe me.. I learned the hard way!!
Good luck.. ( I can't type as finger's are numb now!!)
