Reflex sympathetic dystrophy (RSD) is characterized by a group of symptoms including pain (often
"burning" type), tenderness, and swelling of an extremity associated with
varying degrees of sweating, warmth and/or coolness, flushing,
discoloration, and shiny skin.
How RSD occurs is not known, but there are often triggering events.
Symptoms of RSD often occur in three stages: 1) acute, 2) dystrophic, and
Diagnosis of RSD is based on clinical findings, supported by radiological
Treatment of RSD is most effective in the earlier stages.
Reflex sympathetic dystrophy (RSD) is a condition that features a group of typical symptoms, including pain (often "burning" type), tenderness, and swelling of an extremity associated with varying degrees of sweating, warmth and/or coolness, flushing, discoloration, and shiny skin. RSD is also referred to as
"complex regional pain syndrome," "the shoulder-hand syndrome," "causalgia," and "Sudeck's atrophy."

A variety of events can trigger the RSD, including:
