People experience a variety of pains throughout their lives, and are especially prone to them at the change of seasons. Short-term, non-serious pains do not cause major damage to the body and sometimes serve as a warning to the body. However, chronic pain is different, such as migraine, low back pain, etc., which is not effectively treated for a long time, and some of them can last for decades or even for a lifetime, which is very painful. This kind of chronic pain is very common, difficult to treat and very harmful, some of which seriously affect work and life, and even painful to live. In view of this, the International Academy of Pain (IASP) was established in 1976 at the initiative of many internationally renowned experts in pain medicine to establish pain departments or pain centers in hospitals, uniting medical professionals from multiple disciplines to launch an “attack” on the diagnosis, treatment and research of chronic pain. “In the 1980s, Han Jisheng, the pioneer and founder of pain medicine in China, established the Chinese branch of the IASP, also known as the Chinese Academy of Pain (CASP), in Beijing in September 1989, with Han Jisheng as the president of the Chinese branch of the IASP. On this basis, pain clinics and wards were gradually established in many hospitals to improve pain treatment techniques, and in 1992, according to the instruction of Minister Chen Minzhang, the Chinese Pain Society was subordinated to the Chinese Medical Association and became the Pain Branch of the Chinese Medical Association. In order to better relieve the pain of pain patients and the development of the discipline, the Ministry of Health issued a document in July 2007 that pain departments were established in hospitals above the second level. However, at present, many people are not very clear about the pain department to treat those diseases, the pain department treatment range to do a reading: 1, headache: cervicogenic headache, migraine, post-traumatic headache and other kinds of neuropathic headache. 2, neuralgia: trigeminal neuralgia, intercostal neuralgia, sciatica, acute herpes zoster, postherpetic pain, pain after nerve injury, phantom limb pain, diabetic neuralgia, complex local pain syndrome. 3, osteoarthritis pain: cervical spondylosis, cervical disc herniation, costochondritis, lumbar disc herniation, knee arthritis, heel pain, temporomandibular joint dysfunction syndrome, degenerative osteoarthritis, gouty arthritis. 4.Soft tissue pain: acute and chronic lumbar sprain, lumbar strain, supraspinous interspinous ligamentitis, lumbar dorsal myofasciitis, fibromyalgia syndrome, tenosynovitis, frozen shoulder, tennis elbow, soft tissue injury. 5, ischemic pain: Raynaud’s disease, occlusive thrombotic vasculitis, thrombophlebitis, erythema limb pain, reflex sympathetic dystrophy, etc. 6, cancer pain and pain caused by benign tumors, cancerous thoracic ascites treatment and intra-tumoral chemotherapy. 7.Non-painful diseases: intractable eruption (diaphragm beating), acute facial neuritis (facial palsy), facial muscle spasm. The main treatment methods and principles adopted by the pain department 1. Nerve block blocks block the nerve conduction pathway of nociception, block pain, release spasm, dilate blood vessels, improve blood circulation and tissue metabolism, promote tissue repair of patients and eliminate diseases. It has the advantages of being safe, minimally invasive and less painful. 2.Apply anti-inflammatory drugs to eliminate local non-bacterial inflammation, speed up tissue repair and accelerate disease recovery. The action is accurate, the dosage is small, the side effects are small, safe and reliable. 3.Through silver needles as well as acupuncture treatment, the spastic soft tissue is loosened and blood circulation is improved. Enable many long-term stubborn soft tissue pain to be eliminated. Patients who have been bedridden for eight years due to back and back soft tissue pain and have been transferred to major hospitals without effective treatment have been able to get back on their feet and regain their hope for life. 4.Ablation and decompression through minimally invasive interventional treatment can release the compression of nerves by cervical and lumbar intervertebral discs, so that some patients who are unwilling or unable to undergo surgery can be effectively treated. Through interventional ablation treatment for pathological neuralgia, patients with intractable trigeminal neuralgia and post-herpetic neuralgia are relieved of their pain. 5. Through the final physical therapy and functional training, the treatment effect can be consolidated and recurrent attacks can be avoided.
