The treatments for lumbar disc herniation and spinal stenosis include conservative treatment and surgery. 1. Conservative treatment: patients with less serious symptoms of spinal stenosis can take conservative treatment to relieve symptoms, such as heat therapy, traction, rehabilitation training, etc., to accelerate local blood flow, strengthen the strength of lumbar back muscles, widen the intervertebral space, etc., and can also be assisted by medications, such as oral methylcobalamin, vitamin B1, etc., to nourish the peripheral nerves; intravenous mannitol, dexamethasone, etc., to reduce the edema of the nerve roots, etc.. 2. Surgical treatment: spinal stenosis most often causes numbness and weakness of the lower limbs due to compression of the nerves, leading to intermittent claudication. If the intermittent claudication is more serious, with obvious reduction of range of motion or endurance, or even further reduction of muscle strength, surgical intervention is usually recommended to decompress the spinal canal and prevent irreversible damage to the nerve tissue. The treatment of the same disease varies according to the patient’s physical condition and the stage of the disease, and should be standardized under the guidance of a doctor. The above medications should be used under the guidance of a doctor, avoiding self-medication.
