Spinal stenosis can take methylcobalamin to nourish the nerves, and at the same time, according to the condition of traction, physiotherapy, massage, massage, drugs, pain point closure, surgery and other treatments can be given. Patients with spinal stenosis can take methylcobalamin to nourish the nerves, which in turn can relieve the symptoms of radiating pain and numbness in the corresponding innervated area. However, methylcobalamin cannot treat the root cause of spinal stenosis, which requires surgery. Methylcobalamin alone has limited efficacy and should be used in a combination of treatments. Physical therapy, acupressure, traction, massage, oral medication, and pain point closure can be used to alleviate symptoms when symptoms are mild, and surgery may be necessary if treatment is not effective. Mecobalamin should be contraindicated in patients with a history of hypersensitivity to methylcobalamin or any of the excipients in the prescription. In addition, adverse reactions such as loss of appetite, nausea and vomiting may occur during the use of methylcobalamin, so the drug needs to be used under the guidance of a doctor and avoid self-medication.
