What is nerve block therapy? The so-called “injection” for migraine is called nerve block in pain management, which simply means that the doctor first finds the nerve that causes the headache and then “injects” some anti-inflammatory and analgesic drugs or drugs that improve blood circulation in the vicinity, so as to achieve the purpose of The aim is to treat the headache. In practice, nerve blocks require a high degree of skill, and the accuracy of the injection location determines the effectiveness of the treatment. Is it the same thing as what people call “closed treatment”? Nerve block and closure therapy are not the same. Closed therapy is a method of treating pain evolved from local anesthesia, which is to inject local anesthetics or hormonal drugs into the patient’s painful area to achieve the purpose of anti-inflammation and analgesia, that is, where the pain is hit, the pain is “sealed up”, mainly to solve the “symptoms The main solution is “symptoms”. Nerve block is an injection of anti-inflammatory and analgesic drugs, which acts directly on the nerve that causes the pain, not just the symptom itself, so it is different from “closed treatment”. Is it true that only patients with severe headaches can be treated with nerve block? Many patients may ask, “Do I have to wait until I have a severe headache before I can use nerve blocks? This is a very wrong concept. Treating migraine is like putting out a fire, you need to nip it in the bud when it first starts, the smaller the fire, the stronger the treatment, the easier it will be to put out, and vice versa. If a patient’s migraine attacks every week, regardless of how many times it attacks, he or she should come in for treatment. Some patients may ask, “My migraine can be controlled by taking painkillers, so is there no need for a nerve block? This concept is also wrong. As mentioned above, pain medication only addresses the symptom of “pain”, while nerve block addresses the cause. Nerve block therapy is effective for all degrees of migraine, but it is recommended that patients be treated in the early and middle stages of the disease. Can this treatment be done for migraine patients with chronic conditions such as diabetes, hypertension and coronary artery disease? Although the nerve block is minimally invasive, it is after all an invasive operation and still requires a certain level of physical condition. If the patient’s blood pressure is very high, if the patient is suffering from coronary artery disease, or if the patient is suffering from chest pain, or if the patient’s blood glucose is high, the patient needs to undergo medical treatment first to control these chronic diseases to a relatively ideal state before undergoing nerve block treatment. What are the advantages of this treatment method? The biggest advantage of nerve block therapy is the strong therapeutic effect and relatively few side effects. Take oral medication as an example, after the medication is absorbed into the bloodstream through the stomach, there is no difference in the distribution of the medication in various tissues throughout the body. Originally, the drug only needs to work in the blood vessels of the brain, but now the drug also enters the liver, kidneys and spleen, while the dose of the drug reaches the area that really needs to be treated is very small. Doing a nerve block, on the other hand, allows the drug to be injected around the nerves and blood vessels that need it to work directly, and it uses only one hundredth or even one thousandth of the dose of the oral drug. This can effectively improve the effectiveness of treatment and greatly reduce the toxic side effects of the drug on the body.
