According to a recent story in the Washington Post, more than 25 million American adults — one in ten — reported having continual pain every day during the previous three months, while more than 126 million – over half of all U.S. adults — reported having some sort of pain during the same period.
Another study from the Institute of Medicine found that approximately 100 million adults in the U.S. suffer from chronic pain. Pollster Gallup estimates that 111 million people in America have chronic or recurring pain.
