Reflex Sympathetic Dystrophy, Chronic Regional Pain Syndrome, and Fibromyalgia are three conditions that all have weather sensitive pain as a predominant symptom. Weather sensitive pain is largely caused by the sympathetic nervous system (a portion of the nervous system that controls automatic body functions such as skin swelling, breathing, and heart rate). When this portion of the nervous system does not function as it should several symptoms can occur in addition to weather sensitive pain including irritable bowel and bladder, vison changes, and cold skin temperature. In more severe cases heart rate abnormalities and inability to control of the blood pressure can occur as well. When that occurs the condition may be referred to a dysautonomia.
