Herniated lumbar disk causing leg pain is mainly due to compression of nerves. The main focus is on treating the primary disease, and the treatment methods include physical therapy, medication, and surgery. 1. Physical therapy: such as traction, massage, massage, infrared light, acupuncture and other therapies to promote local blood circulation, so as to improve the symptoms. 2. Medication: Oral medication (such as mannitol) can be taken to reduce the swelling of the nerve root by activating blood circulation and reducing swelling through dehydration. In addition, oral methylcobalamin, B vitamins and other nutritive drugs can be taken to reduce pain and numbness. If the pain is severe, oral ibuprofen extended-release tablets can be taken. 3. Surgery: Surgery can be performed if conservative treatment is not effective or if there is a decrease in muscle strength and numbness in the perineal area. Surgical methods include traditional open nucleus pulposus removal, intervertebral foramenoscopy surgery, and intervertebral implant fusion surgery if there is lumbar instability with spinal stenosis. If the diagnosis of lumbar disc herniation is confirmed, it is recommended that regular treatment be carried out as soon as possible in order to minimize the adverse effects of the disease. All of the above medications should be applied under the guidance of a doctor, avoid self-medication to avoid adverse reactions.
