Most of the lumbar nerve pain is due to nerve root compression by a herniated disc. The main cause of a herniated disc is the protrusion of the nucleus pulposus after the rupture of the annulus fibrosus, and nerve symptoms occur when the nucleus pulposus protrudes and compresses the nerve root. For example, a positive femoral nerve pull test sign, a positive straight leg raise test sign, numbness and radiating pain in the lower extremities, accompanied by pain and heaviness in the buttocks, can also be seen in other lumbar spine diseases resulting in neurological symptoms, such as lumbar spine degeneration and hyperplasia, leading to bone spurs at a later stage, and the bone spurs can compress the nerve roots resulting in neurological symptoms. It can also be seen in patients with severe scoliosis deformity and lumbar spine slippage, which can also be accompanied by nerve root compression symptoms, with pathological manifestations of spinal stenosis and dural sac compression, and severe neurological symptoms, with urinary and fecal incontinence, or even paraplegia.
