Fibromyalgia (FM) is a syndrome of widespread pain, aching and stiffness of muscles, often accompanied by fatigue, sleep disturbances and multiple tender points.

What causes fibromyalgia is not well understood; however, most patients describe a physical trauma, such as a whiplash or neck injury from a car accident, as the beginning of their fibromyalgia pain.
