Many pain patients are not effectively treated for a long time. Even when they are treated, the treatment methods used are mostly the same old methods that were used decades ago – closures, etc. For many pain patients, this method simply cannot reduce pain. Chronic pain is mainly divided into injurious and neuropathic pain, the latter of which is more common, common common painkillers can not solve the problem, the common symptoms are pins and needles, burning, throbbing, knife-like and tearing pain, the skin feels hot and painful to touch more typical. Sometimes the pain can go beyond the original injury, and the original injury has long been improved but the pain symptoms recur and persist, such as the above symptoms should be timely consultation to avoid delays. Pain, especially severe pain, seriously affects the patient’s ability to live and work. The sleepless nights caused by severe pain will soon ruin the patient’s health, and some of them also cause physical dysfunction and disability. Because the causes of pain are so complex, it makes diagnosis and treatment difficult. Many patients move around to multiple hospitals and visit the various departments to which the corresponding organ in the painful region belongs, and the test results are normal or have minor lesions that do not explain the true cause of the patient’s painful symptoms. Often, the specialists are at their wits’ end with regard to the pain. However, after many patients finally visit the pain clinic, the pain physician quickly finds the cause from a professional perspective and the majority of patients’ problems are resolved. Pain involves many different diseases Pain is caused by many aspects, mainly the following six: 1. head and facial pain: trigeminal neuralgia, vascular and cervicogenic headaches, etc. 2.Pain of spinal origin: discogenic neck and low back pain, cervical spondylosis, cervical disc herniation, lumbar disc herniation, lumbar spinal nerve posterior branch syndrome, etc. 3.Cancer pain: pain caused by head and neck tumor, thoracic tumor, pancreatic cancer, liver cancer, primary and metastatic cancer of abdominal cavity and pelvis and bone tumor, as well as pain caused by tumor metastasis invading peripheral nerves. 4.Ischemic pain: Raynaud’s disease, atherosclerotic disease, occlusive thrombotic vasculitis, thrombophlebitis, erythema limb pain, diabetic foot and other resting pain, reflex sympathetic dystrophy, etc. 5.Neuropathic pain: trigeminal neuralgia, postherpetic neuralgia, phantom limb pain, stump pain, diabetic neuralgia and complex regional pain syndrome, etc. 6, bone and joint, soft tissue pain: degenerative osteoarthrosis, frozen shoulder, osteoarthritis, achalasia, temporomandibular joint dysfunction syndrome, soft tissue pain, etc. Principle of pain treatment Pain, especially chronic pain, is the result of a bad pain cycle that develops over a certain period of time. That is: “pain → muscle tension or small-vessel smooth muscle spasm → local ischemia → tissue hypoxia, metabolite accumulation → increased pain-causing substances → increased pain, eventually leading to neuropathy, and in a few cases, irreversible lesions”. The most commonly used nerve block technique in pain treatment, for example, is based on the following principles: blocking the nerve conduction pathway of nociception; reducing sympathetic excitability, dilating blood vessels, improving blood circulation and tissue metabolism; anti-inflammatory effect, eliminating local non-bacterial and immune neuroinflammatory response, which is one of the important causes of pain. Nerve block regulates nerve function, thus interrupting the chain of bad pain circulation and gradually restoring its own virtuous cycle. Some neuropathies are so severe that they cannot be achieved by nerve block alone, and other neuromodulation means such as radiofrequency can also achieve good results. In addition, minimally invasive treatment of cervical and lumbar intervertebral discs can also achieve the purpose of cure. Pain treatment can also go to the “root of the disease” Some patients think that pain treatment is also a closed, the strength of the medicine passed, but also pain, only the symptoms but not the root cause. Cong Yongzhi introduced, in fact, there are many means of pain treatment, including many demanding technical applications. That local pain injection (that is, we all say closed) accounted for less than 5% of the proportion. In the United States, the pain profession is a very mature discipline, with a history of more than 70 years. Contrary to what one might think, pain management mostly addresses both the symptoms and removes the cause. The percentage of cures is much higher compared to other medical and surgical conditions. Chronic pain does not develop in a short period of time in one or two days, and relieving it likewise requires a process. Several advanced techniques for the treatment of pain There are many techniques for the treatment of pain, and different treatment methods are used for different causes and different patients. Radiofrequency technology. Some pain is treated effectively with nerve blocks, but the efficacy is not long-lasting, indicating two problems: one is that it is indeed these nerves that play a role in the pain, and the other is that the pain is damaging the nerves more severely, which requires the use of radiofrequency techniques that can produce long-lasting therapeutic effects and allow the nerve function to resume its own virtuous cycle over a longer period of time. In addition, radiofrequency targeting the intervertebral disc can treat pain of intervertebral origin while preserving the patient’s own intervertebral disc function. Advanced techniques such as spinal cord electrical stimulation neuromodulation technique and subarachnoid morphine pump implantation. provide excellent treatment results for some complex and intractable pain. Spinal cord electrophysiological modulation technology and subarachnoid morphine pump implantation technology are widely used in the U.S. We have introduced these two technologies in the Dalian area and have achieved good results for patients with refractory neuropathic pain and intractable cancer pain, solving pain problems that could not be solved in the past. Minimally invasive is the advantage of pain treatment The application of X-ray and ultrasound technology has expanded the field of pain treatment. Nerve block and radiofrequency technology are two important means of pain treatment. Some nerves such as those in the thoracic, abdominal and pelvic cavities used to require open-chest and open-abdomen surgery to find, but now the pain technology can find the nerve to be treated by percutaneous puncture under X-ray guidance, which greatly reduces the damage to the patient, so minimally invasive is a major advantage of pain treatment. The application of ultrasound allows the pain surgeon to visualize the nerve for the first time, making it possible to find the nerve precisely while avoiding damage to important organs such as blood vessels. In the past, it was impossible to treat some nerves, but it is feasible under X-ray and ultrasound guidance, greatly expanding the field of pain treatment.
