Fibromyalgia a heart sink in the shoes diagnosis. Fibromyalgia is classed as a disorder of pain processing due to abnormalities in how pain signals are processed in the central nervous system. Newer treatments, Duloxetine (Cymbalta) and milnacipran (Savella) may help ease the pain and fatigue associated with fibromyalgia. Amitriptyline or the muscle relaxant cyclobenzaprine maybe prescribed to help promote sleep. None of these treatments offer a cure and symptoms always tend to return. Studies have shown that fibromyalgia is often accompanied by a lactic acidosis. It is thus not hard too imagine that inborn errors of Pyruvate metabolism, that causes lactic acidosis, may play a role in Fibromyalgia. This book explores this possibility and maybe a source of hope for at least some patients.
