What is CRPS?

CRPS, or Complex Regional Pain Syndrome, is an uncommon condition where (typically) one limb experiences pain far beyond what you’d expect from an initial injury.

Aside from pain, symptoms can include swelling, skin color or temperature changes, and heightened touch sensitivity.

CRPS is a biological condition, with measurable physical symptoms. It’s not psychological or “all in the head”.

Other (older) names for this same condition are:

  • RSD (Reflex Sympathetic Dystrophy),‍
  • Algodystrophy
  • Algoneurodystrophy
  • Sudeck’s atrophy
  • Reflex neurovascular dystrophy
  • Causalgia
  • Shoulder–hand syndrome
  • Fracture disease
