Lumbar disc herniation is generally categorized into three types, from mild to moderately severe there are bulging, herniation, and prolapse of the entire nucleus pulposus has been dislodged, which will lead to narrowing of the spinal canal to appear nerve compression symptoms. Of course, there are also patients who have obvious lesions, but the nerve compression symptoms are not obvious, and there is no obvious lower extremity numbness and pain. This situation can be treated without surgery, usually pay attention to maintenance to avoid bending, sedentary, standing for a long time, but relatively speaking, this type is very rare. As long as the nucleus pulposus prolapse leads to nerve compression and numbness and pain in the lower limbs, it is necessary to go through surgery to solve the problem, otherwise the longer the whole nerve is compressed, the more nerve function is lost. At a later stage, even if the nerve compression is lifted by surgery, the nerve function may not be fully restored, so early surgery is the best treatment.
