What I am getting at is many doctors know so little about CRPS and the many treatments that are more recently being used and researched. We, as the patient need to bring new ideas to their attention sometimes or some opportunities that may, or may not help, could be passed up, whether it is LDN, IVIG, Alendronate and other bisphosphonates, Ketamine, or anything else. Doctors, just like most people, have a tendency to get stuck on doing things a certain way. They should be open to new treatment ideas, should be willing to listen to their patients and work with them instead of just sticking with something that worked for one patient at some point in time.
