====== Causalgia ======


The term [[causalgia]] (Greek: kausis – [[burning]], algos – [[pain]]) was introduced by [[Silas Weir Mitchell]] in [[1864]]. It was used to describe a rare [[syndrome]] that followed a minority of partial [[peripheral nerve injury]] in the American civil war. Triad: [[burning pain]], [[autonomic dysfunction]] and trophic changes.

For [[causalgia]], see [[Complex regional pain syndrome]] (CRPS):

CRPS Type II (AKA major causalgia) follows [[nerve injury]] (originally described after high velocity missile injuries). CRPS Type I (AKA [[reflex sympathetic dystrophy]] or causalgia minor) denoted less severe forms, and has been described after non-penetrating trauma
((Sternschein MJ, Myers SJ, Frewin DB, et al. Causalgia. Arch Phys Med Rehabil. 1975; 56:58–63)).

Shoulder-hand syndrome and Sudeck's atrophy are other variant designations. In [[1916]], the [[autonomic nervous system]] was implicated by René Leriche, and the term [[reflex sympathetic dystrophy]] (RSD) later came into use 
((Schott GD. An Unsympathetic View of Pain. Lancet. 1995; 345:634–636))
(but RSD may be distinct from causalgia)
((Ochoa JL, Verdugo RJ. Reflex Sympathetic Dystrophy: A Common Clinical Avenue for Somatoform
Expression. Neurol Clin. 1995; 13:351–363)).
