Pain as a Public Health Problem
"Pain is a significant public health problem. Chronic pain alone affects approximately 100 million U.S. adults. Pain reduces quality of life, affects specific population groups disparately, costs society at least $560-635 billion annually (an amount equal to about $2,000 for everyone living in the United States), and can be appropriately addressed through population health-level interventions."
