Honestly, I think your too young to have to go with either. If I remember correctly, you said you are 18. You are still young and have a great chance of putting this back into remission. I don't know how badly the CRPS is affecting your life, but unless you have expended all other options I would stay away from both. This is just my opinion. I was offered to go with the SCS but went to another doctor to search for more options before going with it. I would ask to see what other options are available for you at your state of dealing with CRPS.
