People with fibromyalgia suffer from chronic pain throughout the body, especially in their joints, muscles and tendons. But research shows that exercise can make patients feel better and improve their quality of life. Dr. Ginevra Liptan, an authority on the disorder at the Oregon Health Sciences Center, has conducted research on how a type of massage therapy of the fascia tissue -- the connective tissue surrounding muscles -- can help relieve discomfort.

Dr. Ginevra Liptan was nearing the end of her first year in medical school when she felt a muscle tear in her neck while exercising at the gym. The injury began a frustrating odyssey of fatigue and chronic pain that was eventually diagnosed as fibromyalgia. She went on to obtain her medical degree and has emerged as a leading authority on the illness. Liptan  recently opened a clinic dedicated to research and treatment of fibromyalgia, called the Frida Center. The clinic in Portland, Ore., is named after Frida Kahlo, the Mexican artist who is thought to have suffered from the disorder.
