Pain medicine is a clinical discipline for the treatment of chronic pain, and as a relatively new department in modern medicine, many people do not know much about it, and even some medical colleagues know very little about it. So, what is “pain medicine”? What diseases are treated? A. Pain is a new discipline: In 2007, the Ministry of Health issued a document No. 227 to establish the first level of pain clinical diagnosis and treatment – pain, that is, the same clinical discipline as surgery, internal medicine. It is stipulated that the main scope of treatment of the pain department is chronic pain (i.e. pain symptoms persist or recurrent pain for more than a month). The Ministry of Health has organized this cadre of specialists who specialize in the treatment and research of chronic pain according to the needs of patients and clinical medicine, as each specialty in medicine specializes in its own specialty and the treatment of its associated pain. Because only with the dedicated research of pain specialists on pain disorders, there will be a breakthrough in chronic pain, a problem that has long plagued the people. The establishment of the pain department is a sign of the country’s strength and wealth, and has changed the social status of the Chinese people who had to “endure” pain because of economic constraints. The World Health Organization has proposed that “it is the basic right of man to be pain-free”. The establishment of the pain department has made the right and desire of the Chinese people to enjoy a high quality of life a reality. What is pain: The World Pain Organization defines “pain” as an unpleasant sensation or emotional reaction of the brain to damage to the sensory nervous system. In 2003, the World Pain Organization clearly divided pain into three major categories: neuropathic pain (sensory nerve tissue damage), injury-receptive pain (sensory nerve peripheral tissue lesions that stimulate the receptors of sensory nerve endings), and psychogenic pain (abnormal foci of excitation in the cerebral cortex). abnormal foci of excitation). Pain treatment can effectively remove the cause of pain for different types of pain, with the ultimate goal of protecting sensory nerves. What does the pain department do: Because the physicians in the pain department specialize in the treatment and research of pain diseases, they know the anatomy and pathophysiology of the pain-related sensory nervous system well, and are able to pinpoint the sensory nerves to which the pain symptoms belong, and have a deeper understanding of the causes and disease patterns. On the basis of learning and applying the original methods of treating pain in various disciplines, we pay attention to and introduce modern advanced technologies, and summarize, improve, innovate and develop them in clinical practice. Therefore, pain physicians will be particularly specialized in finding and relieving the cause of pain, i.e., the cause of sensory nerve damage, and the therapeutic effect will be more outstanding. The treatment method of pain department is a comprehensive treatment with “minimally invasive treatment” as the core, which can remove the cause of sensory nerve compression and increase nerve blood flow by taking advantage of puncture minimally invasive treatment, so that most of the pain can be relieved for a long time. The relationship between the pain department and other disciplines: to treat pain, the location and cause of sensory nerve damage should be clarified first. If the cause is clear, depending on the means and effect of removing the cause, it will be managed by various disciplines that can give the best result. If the cause of pain is difficult to remove or if the patient is unable or unwilling to accept the traditional solution, the pain is delayed as chronic pain, and these chronic pains are managed by the pain department. For sensory nervous system injuries where the cause cannot be removed, such as advanced cancer pain or post-traumatic paraplegia neuropathic pain, the pain department has a variety of approaches to modulate the neurological approach to the cause of the pain to relieve the patient’s pain. For patients with chronic pain whose causes are not clear, the pain department has the responsibility to try to find the location and cause of sensory nerve damage and do its best to relieve the pain for the patients. V. The main chronic pain diseases treated by the pain department 1. head and facial pain: trigeminal neuralgia, cervicogenic headache, glossopharyngeal neuralgia, tumor, vascular pain, etc. 2.Cervical, shoulder, lumbar and leg pain: various types of cervical spondylosis, lumbar disc herniation, degenerative osteoarthritis, lumbar postoperative pain syndrome, sciatica, achalasia, etc. 3, neuropathic pain: herpes zoster and post-herpetic neuralgia, diabetic neuralgia, intercostal neuralgia, post-traumatic neuralgia, post-surgical neuralgia, complex regional pain syndrome, etc. 4, systemic pain: such as osteoporosis, rheumatism, rheumatoid disease, polymyofibrosis, ankylosing spondylitis, etc. 5.Soft tissue pain: acute and chronic lumbar sprain, lumbar strain, myofascial pain syndrome, pear-shaped muscle syndrome, tenosynovitis, frozen shoulder, tennis elbow, etc. 6, cancer pain: advanced cancer pain, bone metastatic pain, etc. 7.Non-painful diseases: such as hyperhidrosis, insomnia, intractable eruption, allergic rhinitis, plant nerve dysfunction, etc.
