The causes of finger numbness include physiological factors, lacunar cerebral infarction, vertebral artery-type cervical spondylosis, carpal tunnel syndrome, diabetic peripheral neuropathy and so on. 1. Physiological factors: when the fingers are pressurized, it can be manifested as numbness and other symptoms, which can be relieved after lifting the pressure. 2. Cavernous cerebral infarction: the onset in the sensory center will cause numbness of the fingers. Aspirin, clopidogrel and other anti-platelet aggregation can be given; simvastatin, atorvastatin and other lipid-lowering; enalapril, valsartan and other blood pressure lowering. 3. Nerve root cervical spondylosis: this disease is mainly caused by the cervical spine degenerative disease. When the nerve root is compressed, methylcobalamin, adenosylcobalamin and other drugs are mainly given to nourish the nerves. When the pain is severe, non-steroidal anti-inflammatory diclofenac and ibuprofen can be given to relieve the pain. 4. Carpal Tunnel Syndrome: This disease is mainly caused by the median nerve compression, after diagnosis, local physical therapy, local closure, or surgical treatment. 5. Diabetic peripheral neuropathy: this disease is mainly due to pancreatic dysfunction, resulting in long-term high levels of blood glucose, resulting in microcirculation disorders, peripheral nerve damage. Clearly diagnosed to give hypoglycemic drugs, such as insulin or oral hypoglycemic drugs such as metformin to adjust blood glucose, and can be given methylcobalamin, vitamin B12 and other nutritional nerve. There are many causes of finger numbness, it is recommended that patients seek medical treatment in a timely manner, under the guidance of the doctor to clarify the cause of the disease, reasonable diagnosis and treatment, and strictly in accordance with the doctor’s instructions to take medication, so as not to cause adverse consequences.
