Exercise may reduce pain from fibromyalgia

In 2005, about 2% of adults in the United States, an estimated 5 million people, had fibromyalgia, according to the Centers for Disease Control and Prevention. The National Fibromyalgia Association estimates a higher number of 10 million people with the disorder. Since pain is a primary indicator of fibromyalgia, individuals may avoid exercise because they assume it will increase their pain. Researchers decided to investigate that belief.
