Research has shown medical hypnosis to be helpful for acute and chronic pain. In 1996, a panel of the National Institutes of Health found hypnosis to be effective in easing cancer pain. More recent studies have demonstrated its effectiveness for pain related to burns, cancer, and rheumatoid arthritis and reduction of anxiety associated with surgery. An analysis of 18 studies by researchers at Mount Sinai School of Medicine in New York revealed moderate to large pain-relieving effects from hypnosis, supporting the effectiveness of hypnotic techniques for pain management.
