Lumbar disc herniation compresses the dural sac, spinal canal, and nerve roots, and pain and numbness are the main symptoms in the early stage, and as the condition develops, weakness of the lower limbs or even paraplegia symptoms will gradually appear. In lumbar disc patients, the herniated disc will compress the dural sac, spinal canal and nerve root, resulting in lumbar pain as well as pain and numbness in the innervated area. The pain and numbness is dominated by radiating pain and numbness in the lumbar region unilaterally or in both lower limbs. If the herniated disc is huge, the compression is obvious, and the disease duration is long it will cause irreversible damage to the nerves. This damage will cause a decrease in the innervation of the lower limbs, manifested as weakness of the lower limbs and unsteady walking. Symptoms of the cauda equina, such as pain and numbness in the perineal area and abnormal urination and defecation, may also occur. If the injury is further aggravated it can cause loss of spinal cord function, resulting in paraplegia of the lower limbs. If symptoms of lumbar disc herniation occur, it is recommended to go to the hospital for examination and treatment under the guidance of a physician.
