Nerve and leg numbness caused by compression of lumbar disc herniation can be treated by general treatment, medication, physical therapy or surgery. 1. General treatment: patients with herniated lumbar intervertebral disc and pinched nerve and leg numbness should take strict bed rest, avoid bending and prolonged labor. After the symptoms of numbness are relieved, the lumbar back muscles should be strengthened to prevent further attack or aggravation of lumbar disc herniation. 2. Medication: Mannitol can be used to reduce nerve edema, methylcobalamin to nourish the nerves, ibuprofen anti-inflammatory and analgesic medication. 3. Physical therapy: Pelvic traction, physiotherapy and other physical methods can help patients reduce nerve compression, thus reducing the symptoms of herniated lumbar disc pressing on the nerve and leg numbness. 4. Surgery: If the symptoms are not relieved by conservative treatment, the patient should be evaluated by a doctor to choose whether or not to undergo surgical treatment, such as nucleus pulposus removal, hemilaminectomy, and so on. Patients with herniated lumbar disc and pinched nerve and leg numbness should go to the hospital in time and have standardized treatment under the doctor’s guidance.
