Lumbar disc herniation: refers to a series of changes due to degenerative changes in the lumbar intervertebral discs, rupture of the annulus fibrosus and herniation of the nucleus pulposus. If the protruding nucleus pulposus compresses the nerve root, cauda equina, or produces inflammatory stimulation, and manifests a series of clinical symptoms and signs, it is called “lumbar disc herniation”, commonly known as “lumbar herniation”. What are the symptoms that need to be suspected of lumbar disc herniation? The most typical symptom of lumbar disc herniation is low back pain accompanied by radiating pain in one limb. Disseminated pain on one side of the limb usually refers to sciatic nerve pain, which radiates from the buttocks to the back of the thigh, the outside of the thigh, the outside or back of the calf, and in some cases, even to the dorsum of the foot and the soles of the feet. This radiating pain is aggravated by coughing and sneezing, walking or after activity. If these symptoms appear, you need to consider whether it is a lumbar disc herniation. Therefore, it is very important to pay attention to sports in general and strengthen the functional exercise of the lumbar back muscles.
