Complex Regional Pain Syndrome (CRPS) is a debilitating and difficult-to-treat condition characterized by excess and prolonged pain and inflammation. Although CRPS can occur anywhere in the body following an injury or other medical event, it usually affects an arm, leg, hand, or foot. Our understanding of this condition is evolving rapidly, but treatment of CRPS requires skillful assessment and up-to-date knowledge. Part of the "What Do I Do Now? Pain Medicine" series, Complex Regional Pain Syndrome presents 11 high-yield clinical cases to cover a broad spectrum of CRPS including epidemiology, diagnosis, differential diagnoses, pathophysiology, conventional and interventional management, choices of neuromodulation, ketamine infusion, spread and prevention, CRPS in pediatric patients, and adjuvant and emerging therapies. This book is an ideal pocket guide for those who are looking for the essentials and advancements needed to manage CRPS.
