Regarding fibromyalgia a person can be diagnosed if they have the following signs and symptoms: pain in at least 11 different tender points. What are tender points? Tender points are areas along the skin that are painful to the touch and which overlie areas of joint and soft tissue pain. These tender points can be in the following areas: hips, knees, neck, shoulders, elbows and chest. They can also be on either side of the body. In addition to a specified number of tender points, an individual must also have had a long-term history of pain lasting for at least 3 months.
