The history of Complex Regional Pain Syndrome (CRPS) is a journey from early observations of battlefield trauma to our current recognition of it as a complex, multi-system neurological disorder.
The first detailed clinical description of what we now call Complex Regional Pain Syndrome emerged during the American Civil War. In 1864, Dr. Silas Weir Mitchell, along with colleagues George Morehouse and William Keen, documented soldiers suffering from "causalgia"—a Greek term meaning "burning pain"—following peripheral nerve injuries. They observed that these soldiers experienced not only agonizing pain but also skin temperature changes and abnormal sweating, foundational symptoms of modern Complex Regional Pain Syndrome.
For over a century, the condition was known by various names, including Reflex Sympathetic Dystrophy (RSD) and Sudeck’s atrophy. These terms often focused too narrowly on the sympathetic nervous system or bone loss. It was not until 1994 that the International Association for the Study of Pain (IASP) adopted the term Complex Regional Pain Syndrome to better reflect the diverse, non-specific nature of the underlying pathology, which involves both the peripheral and central nervous systems.
Historically, patients were often unfairly stigmatized, with their symptoms dismissed as "psychosomatic" due to the lack of visible injury on traditional X-rays or basic neurological exams. Today, we understand that Complex Regional Pain Syndrome is a complex disorder of neuro-inflammation and central sensitization. The development of advanced imaging and a deeper understanding of neuroplasticity have helped move the medical community away from purely psychological explanations toward a biological model that acknowledges the systemic impact of nerve dysfunction.
The treatment landscape has evolved from simple sympathetic nerve blocks to sophisticated interventions. Major milestones include the introduction of spinal cord stimulation, Dorsal Root Ganglion (DRG) stimulation, and targeted infusions like ketamine and neridronate. These interventions mark a significant shift toward managing the refractory pain characteristic of Complex Regional Pain Syndrome. Patient advocacy groups have played a vital role in this progress, pushing for earlier diagnosis and moving the disease out of the shadows of medical mystery.
