Pathology and Current State of Treatment of Chronic Pain

Dear Colleagues,

Laboratory tests, such as imaging and blood tests, are necessary to determine the specific cause of pain and provide guidance for treatment. However, medical research has shown that identifying the cause of chronic low back pain can be difficult, and it is now widely acknowledged that chronic pain can be caused by various factors. Hence, it is crucial to individually investigate the potential causes of chronic pain. For instance, there are reports suggesting a correlation between the degree of knee osteoarthritis (OA) and both deformity and pain severity in musculoskeletal pain. However, there are also reports indicating that there is no such correlation, and a definitive consensus has not been reached. Therefore, more evidence is required. This Topic will feature a study that explores the connection between objective clinical findings and chronic pain in patients.
