Despite the fact that many people have experienced pain, the importance and dangers of pain have not been recognized enough for a long time. About the understanding of pain, in real life, people have a great misunderstanding. 1, “pain is a symptom, not a disease, the disease is well naturally pain” in the long process of medical development, the understanding of many diseases is gradually deepened, many diseases were first only as a symptom, do not get due attention and diagnosis and treatment, along with the depth of the study, only to be recognized as a disease, so as to improve the diagnosis and treatment of these diseases The understanding of pain disorders is in such a deepening process. The distinction between symptom and disease is relative. When a chronic clinical symptom seriously threatens the patient’s quality of life and ability to work over a long period of time, or even causes the patient to commit suicide, it should be recognized as a disease. For example, in primary trigeminal neuralgia, the patient has no other manifestations except pain, and most of the patients suffer from pain, and their quality of life and ability to work are significantly reduced, so primary trigeminal neuralgia should be a typical pain disorder. This disease only has pain, and when the pain is eliminated, the disease is cured. Another example is postherpetic neuralgia, which is also a painful disease. The disease is the result of nerve damage by the herpes zoster virus, and the pain is severe and intractable, lasting up to decades in some patients, with suicides occurring from time to time. Typical pain disorders also include phantom limb pain and stump neuralgia after amputation, post-traumatic injurious neuropathic pain, post paraplegic neuralgia, post-stroke neuralgia, central neuralgia, thrombo-occlusive vasculitis, migraine, myalgic tension headache, cervicogenic headache, menstrual cramps, intervertebral discogenic pain, and chronic low back pain, and so on. These pain disorders have long been described as diseases in the textbooks of various clinical disciplines. It is only that some doctors still believe that “all pain is a clinical symptom of disease, and when the disease is cured, the pain will be gone”, and do not pay due attention to it. Some pain is indeed a clinical symptom of certain diseases, for example, headache secondary to high blood pressure, headache during a cold, abdominal pain during acute abdomen, surgical incision pain, labor pain, etc., which should not be treated as a painful disease. However, pain disorders should not be denied because of the presence of these symptomatic pains. In clinical practice, it should be noted that sometimes mild pain is an early manifestation of a painful disease, and can develop into a serious chronic painful disease if not handled properly. For example, neuralgia caused by intercostal nerve injury after open heart surgery can develop into severe neurogenic pain if not treated early and in time. In clinical work, it is important to clarify which pain belongs to symptoms and which pain belongs to painful diseases. 2, “back pain endure, anyway, can not be cured” Yesterday afternoon, a patient accompanied by family members to the pain department, has been back pain for more than twenty years, he told reporters, this is not even considered a disease, it is in the family under the compulsion of his to come to see a doctor. This reminds me of the saying that life is for enjoying, not for enduring. In real life, patients suffering from chronic pain for a long time leading to a hundred diseases, and even light-hearted patients are not uncommon. The notion that “you don’t have to specialize in pain” is a very old-fashioned and harmful misconception. Timely diagnosis and treatment of pain, effective pain control, is an important element of life and health. The development of science has led to an increasing number of pain treatment methods, from simple drug therapy, nerve block, and gradually developed into a multidisciplinary integrated treatment. After the standardized treatment by pain management specialists, it can be considered that 95% of chronic pain can be treated satisfactorily. With the development of the economy, the improvement of living standards, with pain to take a positive attitude towards treatment is the best policy, delayed treatment often makes acute pain into chronic pain. In recent years, neurobiological studies have shown that the long-term presence of pain stimuli can directly damage the nervous system, the formation of chronic neurogenic pain, which is the main pathogenesis of chronic pain disorders. The pathogenesis of neurogenic pain includes peripheral and central mechanisms. Peripheral mechanisms include ectopic discharge of injured peripheral afferent fibers, neuronal interaction, sympathetic excitation of injured sensory neurons, and the formation of neuromas locally. Central mechanisms include up-regulation of Na+ channels, up-regulation of methyl-mentholatum receptors, massive Ca++ entry into the cell, activation of NO synthesis and other production of peroxides, promotion of neuronal apoptosis, and exacerbation of nerve injury (protein kinase C-dependent). The prolonged presence of painful stimuli can contribute to increased nerve cell excitability, sensitization of spinal cord dorsal horn neurons, decreased function of spinal cord inhibitory interneurons, as well as germination of afferent spinal cord Aβ fibers and sensitization of brain centers. These findings remind us that neurogenic pain should be treated as early as possible to prevent further damage to the nervous system. 3.”Pain department only ‘treats’ pain, but will delay the condition instead” Pain diagnosis and treatment specialties, under the guidance of modern pain theory, carry out a new mode of comprehensive analysis and judgment and treatment for painful diseases and difficult pain problems encountered in clinical medicine, so that Many pain diseases that are difficult to control have been perfectly treated. For example, when confronted with a patient with trigeminal neuralgia, in addition to an exhaustive history and clinical presentation, the superficial sensory and muscular changes of the face will be carefully examined in order to exclude secondary trigeminal neuralgia. Trigeminal sensory and motor conduction velocities, electromyography and evoked potentials will also be examined to assess the electrophysiologic function of the trigeminal nerve. Before primary trigeminal neuralgia can be confirmed, an MRI will be needed to check for vascular or tumor compression around the trigeminal nerve root. For head and face pain, cervical spondylosis, frozen shoulder, intervertebral disc lesion, lumbar back and lower limb pain and other common chronic pain diseases, the use of nerve block, nerve stimulation, medication and other integrated therapies can effectively improve the pain of the local blood circulation disorders, remove inflammatory metabolites, interrupting the vicious cycle of pain, so as to achieve the “symptomatic and fundamental” analgesic effect. It can effectively improve the local blood circulation obstruction of pain, remove the inflammation metabolism products, interrupt the vicious cycle of pain, so as to achieve the “symptomatic and fundamental” analgesic effect. For intractable neurogenic pain such as herpes zoster and its postherpetic neuralgia, trigeminal neuralgia, phantom limb pain, burning pain and other intractable neurogenic pains, the application of specific nerve blocking technology and nerve frequency (heat) electric modulation stimulation, etc., through blocking the pain conduction pathway, improving the state of neural trophism, and adjusting the function of neural conduction, we have achieved a satisfactory effect of pain treatment. For cancer pain, combining with the patient’s physical condition and pain site, applying the latest foreign methods of cancer pain control, highly selective blocking or destroying the nerves that conduct pain, a treatment can mostly achieve a more perfect medium- and long-term analgesic effect. 4. “It is not good to use hormone when treating pain” In the treatment of some aseptic inflammation, it is sometimes necessary to use a small dose of hormone components, but the dosage form used for pain treatment is a suspension, which is mainly used for local action and is strictly controlled in terms of dosage, and it does not have any systemic effect on normal people, which is completely different from the systemic (oral, intramuscular, or intra-venous) large-dose application. The application of large doses is completely different from systemic (oral, intramuscular or intravenous). 5, “pain department is to play closed” Closure therapy originated in the former Soviet Union and the United Kingdom, also known as procaine closure therapy, is the injection of procaine in the human body’s local pain points, in order to block the abnormal stimulation of the lesion site to the brain’s conduction. Many doctors who do not specialize in pain management, and even some nursing staff, due to a lack of systematic knowledge and training, are keen to inject a variety of drugs into pain points, acupuncture points or nerve endings to relieve pain, and they call themselves “closure therapy”. Although it can sometimes relieve the pain of some patients, but there have been many complications and medical disputes, so that some patients and some medical staff on the formal “nerve block” also have misunderstandings, and even fear of psychology. The treatment of pain department is characterized by nerve block and interventional therapy, adopting comprehensive treatment method to eliminate pain quickly and completely and improve the quality of life of patients.
