Abstract: Fibromyalgia (FM) or fibromyalgia syndrome is a clinically defined chronic condition characterized by widespread chronic pain and various somatic and psychological manifestations. Despite the high incidence, due to the lack of specific laboratory diagnostic indicators, it is generally under-recognized in clinical practice, and it is very easy to be missed diagnosis or misdiagnosed. In order to further promote the standardized diagnosis and treatment of FM in China, the Psychosomatics and Rheumatology Cross-subject Group of the Psychosomatics Branch of the Chinese Medical Association invites relevant experts to compile this consensus through referring to the latest guidelines at home and abroad, extensively collecting medical evidence, combining clinical experience and domestic situation. The consensus has strong practicality because it not only standardizes and refines the diagnosis and treatment methods of FM, but also includes the content on comorbidities of mental and psychological disorders and psychotherapy that have been overlooked in previous Chinese FM guidelines or consensuses.
