A lumbar disc herniation of one centimeter is relatively not serious if it does not cause nerve irritation or compression; it is more serious if it causes nerve root irritation or compression, resulting in symptoms such as lumbar and leg pain, sciatica, numbness or weakness of the lower extremities, and so on. Lumbar disc herniation is a degenerative disease of the spine, caused by degenerative changes in the lumbar intervertebral discs (consisting of the nucleus pulposus, cartilage plate, and annulus fibrosus), and rupture of the annulus fibrosus resulting in the prolapse of the nucleus pulposus, which can cause irritation and compression of the nerve roots, thus causing symptoms such as lumbago, sciatica, lower limb pain, and numbness. It can also cause scoliosis, muscle atrophy, incontinence, saddle area sensory abnormalities and other symptoms. Lumbar disc herniation of one centimeter, it is recommended to seek timely medical attention to clarify the diagnosis, under the guidance of the doctor for targeted treatment.
