One form of lumbar disc treatment is: nerve block therapy; so are there any risks associated with nerve blocks? There are certain treatment risks associated with nerve blocks, and the level of risk varies depending on the site of the block, the patient’s physical condition, and the medication used. If the patient is in good health and there are no important organs around the block site, the risk is low. The risk of treatment can also be reduced with the help of some advanced instruments and equipment such as ultrasound and nerve stimulator. Patients often ask: Is nerve block the same as closure therapy? Nerve block is a method of pain treatment evolved from local anesthesia, in which the drug is injected directly into the painful area and local pain points, where the pain is. Nerve block, on the other hand, is a drug injection according to the pattern of nerve travel and innervation. It is a more delicate operation, more precise treatment, more technically difficult, uses drugs with certain requirements, and has a wider range of application, not only for treating diseases, but also for diagnosis. Therefore, nerve block requires a higher requirement for the treating physician and must be operated by an experienced specialist. Why closure cannot be commonly used? The drug formulation of closure therapy consists of anesthetics and hormonal drugs. Anesthetics are local anesthetics, which generally have a small effect on the body, but long-term, large amounts of hormonal drugs can cause osteoporosis and affect blood pressure and blood sugar. Therefore, when making local closure, the amount of drugs should not be too large and the interval time should not be too short. Is nerve block only a transient anesthesia or can it treat the disease? In chronic pain treatment, therapeutic nerve block is the injection of anti-inflammatory and analgesic drugs around the injured nerve, neuromodulatory block is the regulation of nerve physiology and biochemistry to interfere with the nerve conduction to pain, and destructive block is the destructive block of the diseased nerve, all of which interrupt the vicious cycle of pain process by blocking the nerve conduction and finally achieve the purpose of treating the disease. Which treatment is used to stop the pain of a herniated lumbar disc also needs to vary from person to person and suit the basic constitution of the patient to achieve the best results.
