Explanations and treatment of fibromyalgia syndrome (FMS) and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) are controversial, and outcomes are poor. This paper describes sensation-suppression theory, a theory modelled on self-organizing control systems that are capable of adaptation in response to inputs and used in applications of artificial intelligence. The theory shows how the need to suppress inflammatory and other causes of pain or fatigue due to challenging circumstances sensitizes the neurological processing of pain and fatigue, thereby creating the amplified sensations and abnormal cognitions of central sensitivity syndromes. These syndromes are caused by errors in an evolutionarily early behavior-control mechanism of animals that comes into conflict with the later cognitive behavior-control mechanism of humans. Unlike the cognitive and current biological theories, the sensation-suppression theory explains both the personality and biological risk factors for central sensitivity syndromes and why onset is sometimes gradual and sometimes sudden. A specific form of autonomic dysregulation that could act as a new empirical test of the theory is suggested. Recovery is achieved by reversing the biological homeostatic dysregulation through a specific form of pacing where the person changes from one short, non-stressful activity to another, and where activity is calibrated to the level of illness and the patient’s current biological state. Recovery is hampered or prevented by systemic inflammation and lifestyle obligations. The theory provides a sympathetic narrative for the cause and treatment of FMS and ME/CFS and promotes a recovery lifestyle that prioritizes the needs of the patient. Prevention requires hearing what the body is saying.
