What is reflex sympathetic dystrophy?

Reflex sympathetic dystrophy refers to type I complex regional pain syndrome. Complex regional pain syndrome is a chronic pain condition that mainly affects the arms or legs and is often triggered by injury.[1] It is characterized by constant pain, sensitivity, and skin color and temperature changes at the site of an injury. The pain is out of proportion to the severity of the injury and worsens with time.[1] In type 1 the underlying nerve injury cannot be identified.[1]
