The autonomic nervous system rears its head in fibromyalgia – again. The pattern in fibromyalgia is now pretty clear; the fight/flight (sympathetic nervous system) system is activated even during rest, the heart rate response (chronotropic incompetence) to exercise is in the pits, and the sympathetic nervous system – overactive during rest – poops out when under stress. Plus the baroreflex response, which maintains blood pressure, and regulates autonomic nervous system functioning, is not working properly either.
