Lumbar anesthesia is not painful. The operation like lumbar anesthesia is very common in the clinic and technically very mature, so the operation process is very smooth for most patients. In addition, before the operation, the doctor will first apply local infiltration anesthesia to the puncture site, that is, at the puncture site to the skin, subcutaneous, muscle, ligament and other parts of the injection of anesthetic drugs. After this, the puncture is performed without causing severe pain to the patient. Some patients may feel more pain during the puncture due to poor positioning or excessive tension. In fact, if the procedure goes smoothly, it does not take too long and there is no significant pain during the procedure; in addition, after a smooth anesthesia, the area of nerve distribution below the puncture point will continue to feel no pain due to the injection of anesthetic drugs. Therefore, if the doctor recommends this type of anesthesia, the patient does not need to be particularly nervous, but needs to cooperate with the doctor in the relevant position and remain relaxed.
