The mystery of pain as a disease: Elliot Krane on TED.com

We think of pain as a symptom, but there are cases where the nervous system develops feedback loops and pain becomes a terrifying disease in itself. Starting with the story of a girl whose sprained wrist turned into a nightmare, Elliot Krane talks about the complex mystery of chronic pain, and reviews the facts we’re just learning about how it works and how to treat it. (Recorded at TED2011, March 2011, in Long Beach, CA. Duration: 8:04)
