Lumbar disc herniation weakness in both feet is mainly caused by lumbar disc herniation, which leads to the reduction of the volume of the spinal canal and the compression of the nerves. After the lumbar disc herniation, the volume of the spinal canal will be reduced, and the nucleus pulposus will squeeze the nerves, causing nerve edema, inflammation, etc., and movement disorders. The nerves will be damaged by long-term pressure, and the muscles innervated by the compressed nerves will have reduced muscle strength, resulting in weakness of the feet. Lumbar disc herniation leads to lower muscle strength of the lower limbs, which is manifested as weak legs and feet, which is a more serious manifestation of nerve damage. A herniated lumbar disc can be treated with traction and infrared physical therapy. In severe cases, surgical procedures such as laminectomy are required. Patients with lumbar disc herniation and weakness of legs are recommended to be admitted to the hospital for examination in time, to clarify the cause of the disease and to carry out symptomatic treatment, and to pay attention to staying in bed in daily life, avoiding bending over and doing heavy physical work to avoid deterioration of the condition.
