Diagnosis and management of fibromyalgia?
Diagnosis is clinical and sometimes refers to the American College of Rheumatology
classification criteria which lists 9 pairs of tender points on the body. If a patient is tender in at least 11 of these 18 points it makes a diagnosis of fibromyalgia more likely
Explanation
Aerobic exercise: has the strongest evidence base
