Reflex sympathetic dystrophy. Objective clinical signs in diagnosis and treatment.

Diagnosis and follow-up treatment of reflex sympathetic dystrophy is difficult because of the subjective, nonspecific nature of its primary symptom, burning pain. Early diagnosis and aggressive treatment of reflex sympathetic dystrophy with epidural nerve blocks improves clinical resolution. Temperature difference between extremities and dependent cyanosis are reliable objective signs for clinical diagnosis and the evaluation of progress for treatment for reflex sympathetic dystrophy.
