The mystery of chronic pain

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.  We couldn’t resist posting this video to illustrate this statement.  Starting with the story of a girl whose sprained wrist turned into a nightmare, Elliot Krane, director of Pain Management Services at Lucile Packard Children’s Hospital at Stanford, 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.
