To solve the numbness of the fingers, we should find the triggers in time and treat them. Common causes include mechanical compression, diabetic peripheral neuropathy, and insufficient blood supply to the brain. In terms of treatment, the main thing is to lift the mechanical compression, for the original cause of the disease, such as medication. 1. Mechanical compression: commonly seen in sleeping, due to improper sleeping posture, resulting in prolonged arm pressure, may cause numbness of the fingers. In this case, the improper sleeping posture should be corrected in time, to lift the mechanical compression, and appropriate activities of the arm. It is conducive to restoring local blood supply and relieving the symptoms of finger numbness. 2. Diabetic peripheral neuropathy: this disease can lead to patients with peripheral nerve damage, resulting in poor blood flow of nerve endings, may cause numbness of the fingers. Metformin or insulin and other hypoglycemic drugs can be applied to control blood sugar. Neurotrophic drugs such as B vitamins and methylcobalamin can be applied to promote the recovery of damaged nerves and improve the above symptoms. 3. Insufficient cerebral blood supply: Due to the obstacle of blood circulation in cerebral artery, resulting in ischemia and hypoxia of brain tissues, it may cause numbness of fingers, and may be accompanied by dizziness, headache, drowsiness and other symptoms. Anti-platelet aggregation drugs such as clopidogrel and aspirin can be applied. With the application of Vibramycin, nimodipine and other drugs to expand the cerebral blood vessels, to restore the blood supply to the brain tissue, to solve the symptoms of numbness in the fingers. Finger numbness can also be caused by carpal tunnel syndrome, cervical spondylosis and other causes of nerve compression caused by the use of methylcobalamin to improve the symptoms, if necessary, feasible surgical treatment. If the symptoms of finger numbness cannot be relieved for a long time, you should consult a doctor as soon as possible, complete the relevant examinations, diagnose the cause and then give targeted treatment.
