Decent article: What Fibromyalgia Feels Like
Interesting paragraph:
Dr.Teitelbaum shares, “Fibromyalgia represents an ‘energy crisis’ where the body is spending more energy than it is able to make. When this happens, the area using the most energy for its size malfunctions, acting like a circuit breaker that has been overloaded and goes off-line. This is an almond-sized gland in the brain called the hypothalamus. It controls sleep, causing the paradox of being unable to sleep despite being exhausted, which is the hallmark of this condition. The circuit also controls our hormonal system and autonomic system (blood pressure, gut, pulse, and sweating).”
