Psychosocial factors in chronic pain in the dysvascular and diabetic patient.

ABSTRACT

Dysvascular and diabetic patients are faced with high rates of chronic pain as a consequence of numerous secondary sequelae, including diabetic neuropathy and limb loss. Researchers and scientists have put forth a tremendous amount of effort to understand the complex nature of pain in this population of individuals, as well as others with chronic pain secondary to illness and injury. The emergent understanding of anatomy and sensory physiology within the past century has fueled an initial focus of understanding pain from a purely neurologic and biochemical perspective. Over the past few decades, the field has moved toward an understanding of pain as a process involving the dynamic interaction of biologic, psychological, behavioral, and social variables. This article provides a brief overview of several psychosocial processes, cognitive, affective, and behavioral, that have emerged as influential to the experience, impact, and treatment of pain.
