Hi. I think from people I know who have had the scs it really varies from person to person. I am assuming since you have had rsd for so long you have tried a lot of treatments? You stated you are ketamine but have you done the infusions? How did you respond to things like blocks etc? Do you feel comfortable with the doctor who is doing the scs and does he or she treat a lot of rsd patients? I think that is very key.
Welcome to the forum by the way though sorry you are facing this
