Complex Regional Pain Syndrome (CRPS)

Complex Regional Pain Syndrome (CRPS)

Complex Regional Pain Syndrome (CRPS) or as it used to be known Reflex Sympathetic Dystrophy (RSD) Syndrome is serious chronic pain condition. It can last for years and sometimes be a lifelong condition.



CRPS is a complex amplified musculoskeletal pain syndrome (AMPS) condition that broadly describes chronic pain affecting one or more of the limbs. CRPS usually develops after injury. There is little known about the exact cause of CRPS/RSD and symptoms are varied.

  • Burning or Itching sensations
  • Dull, tearing or aching pain
  • Swelling and inflammation
  • Changes to the skin

To properly diagnose CRPS providers must rule out other possible conditions such as arthritis, neuropathies and vascular disorders. It is a disorder of the sympathetic nervous system and is characterized as constant pain that is out of proportion to the original condition or damage causing injury.
