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 for it to escape diagnosis or be 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 organized 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 on the one hand, it standardizes and refines the diagnosis and treatment methods of FM, and on the other hand, it also includes the content on comorbidities of mental and psychological disorders and psychotherapy that were overlooked in previous Chinese FM guidelines or consensuses.
