PAIN MANAGEMENT

Pain management is an important branch of modern medicine, aiming to improve patients’ quality of life by scientifically assessing, alleviating, and controlling acute and chronic pain. Pain has been listed as the “fifth vital sign” by the World Health Organization, and its management encompasses various methods including pharmacological therapy, physical therapy, interventional therapy, and psychological intervention. Chronic pain (lasting more than 3 months) is considered an independent disease, such as neuropathic pain, cancer pain, and osteoarthritis pain, requiring long-term, comprehensive management strategies.
