Recurrent reflex sympathetic dystrophy as a manifestation of systemic lupus erythematosus.

Reflex sympathetic dystrophy (RSDS) is a syndrome of hyperesthesia and vasomotor disturbance of an extremity, often following trauma or an inflammatory process. We describe a patient with systemic lupus erythematosus (SLE) and recurrent RSDS involving all 4 extremities at various times during her illness. Treatments, including corticosteroid use, physical therapy and at times sympathetic nerve blockade led to the resolution of each episode. We suggest the diagnosis of RSDS be considered in patients with connective tissue diseases who present with atypical pain syndromes not attributable to their primary illness.
