The effect of hypnosis on the experience of fibromyalgia pain in a number of subjects was studied while using magnetic resonance imaging (MRI) of the brain. Suggestions with hypnosis and the same suggestions without hypnosis were used to increase or decrease the subjective experience of fibromyalgia pain. Patients reported significantly greater pain control and pain reduction when hypnotised. The MRI scan confirmed that activation of brain areas was of greater magnitude when suggestions followed a hypnotic induction.
