Paul Biegler - a science journalist and former doctor - has interviewed the world's leading pain experts, along with people who have weathered their own chronic pain battles.

Chronic pain is the single biggest cause of suffering. And yet, pain that persists for more than three months is often unrelated to any physical injury. So why does it still hurt?

From neuroplasticity to sensitised nervous systems and associative learning, Dr. Biegler's journey through pain clinics and studies debunks common myths about pain treatments and explores the pivotal recent brain science that explains why a nervous system holds on to pain pathways, and how to retrain the brain and the body.

Discover what we can learn from leading pain doctors and the pain clinics that offer no pain medications but still have excellent (and fast) results.
