Sudden numbness of the fingers consider peripheral neuritis, cervical spondylosis, peripheral nerve compression, give imaging and electrophysiological examination, physical therapy, drug therapy, surgery. Finger numbness should first go to the hospital for examination, usually do cervical spine magnetic resonance, electromyography, in order to determine whether there is damage to the nerves and the severity of the damage, to find the cause of the disease for symptomatic treatment. If it is peripheral neuritis, no obvious nerve compression, can be given oral nutritional nerve drugs, including methylcobalamin tablets, vitamin B12 tablets, to remove the cause of the disease, such as diabetes, need to manage the blood sugar. If it is caused by infection, the infection needs to be controlled as soon as possible. If it is cervical spondylosis, the nerve in the neck is compressed leading to numbness in the fingers, cervical traction can be carried out, oral nutritional nerve medication and anti-swelling medication (Diosbulbin tablets), if the symptomatic joints are not obvious, surgery can be considered. If it is peripheral nerve entrapment, including carpal tunnel syndrome, elbow tunnel syndrome, finger numbness caused by peripheral nerve entrapment, it is recommended to reduce the inappropriate posture of the elbow and wrist and repeated activities, to avoid local tissue swelling and entrapment of the nerve. Nutritional nerve medication can be taken orally, local hot compresses, physical therapy (microwave) to promote local blood circulation, effectively reduce nerve entrapment. If conservative treatment has no effect, it can be treated by surgery. Numbness of the fingers is recommended to actively consult a doctor, under the guidance of a physician. The use of drugs need to follow the doctor’s instructions.
