Complex regional pain syndrome (CRPS) is a debilitating, painful condition in a limb associated with sensory, motor, autonomic, skin and bone abnormalities. Pain is typically the leading symptom, but is often associated with limb dysfunction and psychological distress. Prompt diagnosis and early treatment is required to avoid secondary physical problems related to disuse of the affected limb and the psychological consequences of living with undiagnosed chronic pain. UK guidelines have recently been developed for diagnosis and management in the context of primary and secondary care. The purpose of this concise guideline is to draw attention to these guidelines. Information in this article has been extracted from the main document and adapted to inform the management of CRPS as it presents to physicians in the course of their daily practice.
