Fibromyalgia is an idiopathic rheumatic disease characterized by diffuse pain throughout the body and tenderness at specific sites

as well as a variety of non-specific clinical symptoms. The name of the disease in traditional Chinese medicine（ TCM） is often based on the main symptoms. Based on the following four aspects

i. e. site of somatic pain: 1) fibromyalgia is consistent with the concept of "tendon"in TCM

2) the core symptom diffuse pain is the main clinical manifestation of tendon numbness. 3) the liver numbness and fibromyalgia caused by tendon numbness are consistent with many non-specific symptoms. 4) fibromyalgia occurs in middle-aged and elderly women and is consistent with the intrinsic etiology of tendon numbness; it is believed that fibromyalgia should be attributed to the category of "tendon numbness"in TCM.
