Dysautonomia is a condition where the autonomic nervous system does not work right.  The autonomic nervous system is responsible for controlling automatic functions in the body such as heart rate, blood pressure, pupil size, bowel and bladder urges, skin temperature, and even limb swelling.     Many people with chronic pain never consider that rather then sensory or motor nerves, muscles, tendons, ligaments, and bones there is yet another major source of musculoskeletal pain.   The sympathetic nerves (that is their name) which are part of the autonomic nervous system, can actually cause more severe pain then each of the other tissue types just named.  When involved light touch, changing barometric pressure, and changing temperature can hurt.  Weather sensitive pain, as seen with conditions like arthritis, necks, backs, head ache, RSD/CRPS, and Fibromyalgia, is a true sign that there is dysautonmia of the sympathetic nerves.  The good news is that there is a way to identify it (medical thermology) and there are ways to treat it.
