Pain relief involving hypnosis remains mysterious but can no longer be called a myth. Pain, after all, is a composite experience produced by various parts of the central nervous system, not simply the result of tissue damage.
Psychological techniques and interventions that modify activity in the brain and spinal cord can alter pain perception.
During a clinical hypnosis session, a trained professional brings about a trance-like state of heightened inner concentration and then helps the patient via suggestions geared towards better emotional or physical well-being.
