Fibromyalgia Syndrome - Fibromyalgia syndrome (FMS) is a chronic pain disorder characterized by widespread muscle pain and fatigue. Fibromyalgia means pain in the muscle, ligaments and tendons - the fibrous tissues in the body. Syndrome means a set of symptoms that occur together. FMS affects 3 to 6 million Americans, and is more common in women than men. Because the pain and symptoms of FMS are not visible, it may be under-diagnosed.

Phantom limb pain is a common problem for people following amputation of a limb. It can be resistant to simple painkilling techniques and many people with phantom limb pain face a lifetime of suffering. Some people may benefit from TENS or surgical implants to the spinal cord or brain, but even these techniques may not give good pain relief. The pain may be constant and disabling and often the person perceives the limb to be held in a cramped, uncomfortable position.
