Numbness of legs and feet due to compression of nerves by lumbar disc herniation can generally be relieved by medication, traction and surgery. 1. Medication: The protruding nucleus pulposus of lumbar intervertebral disc herniation can compress the nerves and cause numbness of legs and feet, which can be treated by medication, such as methylcobalamin, to nourish the nerves and relieve the symptoms. 2. Traction: The lumbar intervertebral space can be enlarged through traction to reduce the pressure on the nerve root, thus relieving the symptoms of numbness in legs and feet. 3. Surgery: Generally, if the effect of conservative treatment is not obvious, the patient can be treated by surgery, such as minimally invasive intervertebral foramenoscopy, to remove the protruding nucleus pulposus and relieve the compression on the nerves, which can relieve the symptoms well. It is recommended to go to the hospital for CT or MRI examination in time, and choose the appropriate treatment according to the actual situation.
