Chronic pain is a widespread problem in the United States. According to statistics from the Centers for Disease Control and Prevention, an estimated 50 million Americans suffer from some form of chronic pain; nearly 20 million of those people have high-impact chronic pain , which is persistent and affects a person’s ability to carry out day-to-day activities, resulting in a lower quality of life. Chronic pain is also frequently associated with a higher prevalence of mood disorders such as depression and anxiety.
