Clinical Information
  • A rare neurologic syndrome characterized by burning pain, tenderness, swelling, and changes in the skin color and temperature of a body part or extremity. It is usually caused by injury or surgery.
  • A syndrome characterized by severe burning pain in an extremity accompanied by sudomotor, vasomotor, and trophic changes in bone without an associated specific nerve injury. This condition is most often precipitated by trauma to soft tissue or nerve complexes. The skin over the affected region is usually erythematous and demonstrates hypersensitivity to tactile stimuli and erythema.
