This article reports that the CDC finds that Physical Therapy is better than pain meds for chronic pain. This should be true of hypnosis and related techniques. Combining appropriate movement/exercise with mind techniques should be the best of all!
A staggering 25 million Americans suffer from chronic pain, according to the National Institutes of Health (NIH). A January 2015 report notes physical therapy as a suitable, non-pharmaceutical alternate for chronic pain management. The Centers for Disease Control & Prevention (CDC), in its newly released guidelines as of March, specifically highlights physical therapy as a safe and more effective treatment measure for chronic pain compared with opiates such as Vicodin and OxyContin. Additionally, the CDC reports that opioid use led to more than 28,000 deaths in 2014 alone. Unlike acute pain, attributed to a specific ailment such as burn or fracture, and spanning from the time of injury to approximately 7 to 10 days, chronic pain is discomfort persisting for 3 months or more and carries an emotional component. The American Chronic Pain Association (ACPA) describes chronic pain as "pain that continues when it should not."
