Yes, Clinical Hypnosis can help with pain management. The brain is the processor of all pain, receiving the signals to experience it from the rest of the Healthy Body. Hypnosis helps move the Healthy Body out of a state of alarm, allowing the brain to pay less attention to potential signals of tissues damage. Trance stimulates serotonin and noradrenaline.
These chemicals naturally slow the transmission of pain signals. It also stimulates natural anesthetics such as endorphines and enkephalins. If it is psychosomatic pain, hypnosis can be beneficial to release those mental blocks creating the issue.
