Chronic pelvic pain refers to pelvic pain that is non-cyclical, lasts for more than 6 months (some believe it lasts for more than 3 months), and is ineffective for non-opioid drug treatment. Chronic pelvic pain is one of the most common symptoms in women. Pelvic pain can be acute or chronic. Acute pelvic pain is caused by lesions or injuries of pelvic organs, with an acute onset and typical clinical manifestations. It may be accompanied by neuropsychiatric symptoms such as depression, suspicion or anxiety. Such patients may also show a variety of psychological disorders, such as abnormal sleep and personality disorders. The diagnosis is usually not difficult and can generally be cured in a short period of time. The characteristics of chronic pelvic pain (CPP): the cause is complex, and sometimes even laparoscopy or laparotomy cannot find an obvious cause, and the degree of pain is not necessarily proportional to the degree of the lesion. Psychological chronic pelvic pain should be considered as a physical symptom caused by psychological factors. It is often diagnosed as functional chronic pelvic pain in clinical practice. According to the modern bio-social-psychological medical model theory, it is called psychological (or mental) chronic pelvic pain. A considerable number of patients with pelvic pain have been found to have no organic lesions after various examinations, but they repeatedly complain of pelvic pain. Psychological factors may play an important role in the development of the disease.
