Lumbar 5-sacral 1 herniation is not serious if it only appears as a protrusion on CT and MRI without clinical symptoms, such as low back pain, numbness and pain in the lower limbs and dysuria. If lumbar 5 sacral 1 herniation is clinically manifested as obvious low back pain, as well as numbness and pain of lower limbs or urinary and fecal disorders, it is more serious, and CT or MRI examination can see that the herniation is more obvious and compressing the nerve or dural sac. If the protrusion of lumbar 5 sacral 1 is serious, active treatment should be carried out to relieve the symptoms of low back pain and numbness and pain of lower limbs at an early stage, and if necessary, surgical treatment should be carried out to release the compression of the herniated disc on the nerves, so that the clinical symptoms can be relieved or disappear.
