Fibromyalgia is a condition that causes pain and tenderness in the head, shoulders, upper back, thighs, and abdomen. People with fibromyalgia also often have headaches, fatigue, anxiety, depression, and sleep problems. The cause of the condition is unknown. Fibromyalgia can be diagnosed when a person reports chronic, widespread pain and has tenderness to pressure at particular locations on the body. There are no specific laboratory tests for fibromyalgia. Although there have been studies of many types of treatments for fibromyalgia, none have proved to be highly effective. Many people with fibromyalgia seek alternative treatments, such as acupuncture. Acupuncture is an ancient Chinese treatment that involves the placement of special needles into specific points of the body to treat medical conditions. Increasingly, mainstream medicine is recognizing acupuncture as an effective treatment for a variety of disorders. Unfortunately, no studies prove that acupuncture helps patients with fibromyalgia. A common problem with previous studies has been the lack of good control groups. Patients knew whether they were getting true acupuncture, and this could have influenced the way they reported symptoms.
