Chronic pain affects over 100 million US adults and 20 percent of children worldwide. Each year, Americans spend billions of dollar on medications, surgery and therapies in a quest to find relief - often leading to more suffering and hopelessness. Chronic pain is complex.

Dr. Christo explains the complex nature of pain and provides a wide range of tools and techniques scientifically proven to help patients control and defeat it.
