Han Jisheng, chairman of the Chinese Medical Association’s pain branch, pointed out in an article that pain is one of the main vital signs of human beings and has important biological significance, and the whole society should pay attention to the importance of pain. Han Jisheng said that the significance of acute pain is its “warning” effect, and more than 50% of patients visit the doctor because of pain, so acute pain is called “good pain”. In contrast, chronic pain that lasts more than three months and is difficult to treat can only play a destructive role in physical and mental health and quality of life, and this pain is considered “bad pain” and should be eliminated. People usually think that “pain is a symptom, not a disease, and it will stop when the disease is cured”. In fact, most chronic pain is not only a “symptom”, but also a disease in itself. For example, trigeminal neuralgia, post-herpetic pain, etc. “If the pain is cured, the disease will be cured. In addition, the development of science has led to an increasing number of pain treatment tools, the efficacy of the treatment continues to improve, and it can be considered that 95% of chronic pain can be satisfactorily treated. It is reported that the International Pain Society’s slogan for the first World Analgesia Day is: “Pain relief is a fundamental right of patients.” Some people think that “the pain department only cares about treating pain, but will delay the disease,” Han Jisheng said this is a misunderstanding, because the pain doctor is in accordance with the Chinese Medical Association Pain Society compiled the “clinical pain diagnosis and treatment guidelines”, “clinical pain diagnosis and treatment practice” requirements to make a good diagnosis, and then only to carry out treatment.
