RSD is a descriptive term meaning a complex disorder or a group of disorders that may develop as a consequence of trauma affecting the limbs, with or without an obvious nerve lesion. RSD also may develop after visceral diseases or CNS lesions or, rarely, without an obvious antecedent event. It consists of pain and related sensory abnormalities, abnormal blood flow and sweating, abnormalities in the motor system, and changes in structure of both superficial and deep tissues ("trophic" changes). Not all components need be present.
