There is no absolute fastest way to recover from facial numbness. The causes may be related to cerebral infarction, trigeminal nerve damage, multiple sclerosis, diabetic peripheral neuropathy, etc. Targeted treatment is usually required. 1. Cerebral infarction: the blockage of cerebral stenosis leads to ischemic infarction of local brain tissue in the brainstem, resulting in numbness of the opposite side of the limbs and face. Aspirin, statin and other drugs can be applied to improve blood supply, and cerebrovascular intervention is necessary. 2. Trigeminal nerve damage: trauma, tumor infiltration and other factors lead to sensory abnormalities in the upper and lower jaws, etc. Surgery can be used to repair skull base fracture and other injuries, and remove the tumor to avoid compression and invasion of the trigeminal nerve. 3. Multiple sclerosis: autoimmune abnormalities lead to chronic demyelinating lesions in the central nervous system, resulting in central trigeminal nerve dysfunction. Teriflunomide, fingolimod, natalizumab, azathioprine and other drugs can be applied. 4. Diabetic peripheral neuropathy: long-term high blood sugar leads to peripheral neuropathy, trigeminal nerve dysfunction, can take metformin, selegiline and other hypoglycemic drugs or subcutaneous injection of insulin to control blood glucose, and the application of methylcobalamin, vitamin B, epothilone, lipoic acid, and other drugs such as nutritional nerve. All of the above drugs should be used under the guidance of a doctor, and should not be used blindly on their own, so as not to cause adverse consequences.
