Pain and Pain Medicine Pain is an unpleasant somatic sensation and emotional experience that accompanies tissue damage in our bodies. In many diseases, pain is often the main symptom, such as: cervical spondylosis, lumbar intervertebral disc herniation, osteoarthropathy, headache, neuralgia, cancer pain, etc., which is also known as the clinical pain disease, the incidence of this type of disease is high, but many patients have not been effectively diagnosed and treated, in order to solve the clinical needs and to comply with the development of modern medicine, an emerging discipline of integrated medicine — pain medicine was born. -In 2007, the Ministry of Health of the People’s Republic of China stipulated that “Pain Medicine” be added to the list of medical institutions’ diagnostic and treatment subjects, and it mainly carries out the diagnosis and minimally invasive treatment of chronic pain. World Day Against Pain Since 2004, the International Academy of Pain (IASP) has designated the third week of October every year as “Global Day Against Pain”, with a different theme every year, and China has designated the third week of October every year as “China Analgesia Week”. China will set the third week of October each year as “China Analgesia Week”, the same period to carry out activities; in recent years to raise the degree of attention to various types of pain disorders, to strengthen the research on various types of pain disorders, publicity, will be set from October each year to the following October as the “World Day Against Pain,” October 19, 2015 is this year’s “October 19, 2015 is this year’s World Analgesia Day, and the theme is “Focus on Joint Pain”. Bone and joint pain Bone and joint pain is the most common type of pain in clinical practice, and there are many diseases that cause bone and joint pain, including degenerative osteoarthritis, bursitis, frozen shoulder, osteoporosis, osteoporosis, rheumatoid arthritis, necrosis of the femoral head, etc. To deal with different kinds of diseases that cause bone and joint pain, it is important to take a look at the different kinds of diseases that cause bone and joint pain. Diagnosis and treatment of bone and joint pain caused by different kinds of diseases vary. Many patients with bone and joint pain will go to orthopedics, rheumatology, endocrinology or neurology respectively. Different clinical departments have corresponding diagnostic and treatment standards and methods, but in the treatment of bone and joint pain, the pain department has its unique characteristics and advantages compared with other departments: 1, a better understanding of the pharmacological properties of various analgesic drugs. 2, more concerned about the treatment of disease while the treatment of the disease, and also the treatment of femoral head necrosis. 2, more concerned about the treatment of disease at the same time to relieve pain symptoms. 3, more specialized in the application of minimally invasive interventional techniques for the treatment of intractable pain. Minimally invasive interventional therapy Minimally invasive interventional therapy in Pain Medicine is different from the interventional therapy of radiology, which is the use of intravascular catheter operation technology, although under the support of computerized digital subtraction angiography system (DSA), the lesions involving the blood vessels of the human nervous system are implemented in a single diagnosis or treatment, in order to achieve the purpose of embolization, dissolution, expansion and shaping and anti-tumor and so on. Minimally invasive interventional therapy in pain department is mainly for the treatment of pain-related diseases arising from injury, chronic inflammatory stimulation or compression of the nervous system, which is a clinical technique for the direct treatment of the nervous system itself and peripheral lesions with the help of DSA, CT or C-arm and other X-ray imaging guidance or supervision. Its advantages are that it can obviously release the nerve-related irritating factors and adhesion state, with small trauma, relatively precise operation, precise efficacy, few complications and relatively high safety coefficient, and it is one of the main core technologies of pain discipline.
