       The hand is one of the most flexible parts of our body, which can complete a lot of fine work. If any discomfort occurs to the fingers, it will affect our normal hand activities.

  Especially when hand numbness occurs, in addition to affecting hand movement, it may also indicate these diseases.

  Short term hand anesthesia: normal

  After the afternoon nap, the whole arm is numb, like countless ants crawling, and the numbness will gradually disappear after a rest of 5-10 minutes.

  This physiological numbness is mainly caused by insufficient local blood supply due to poor posture, poor peripheral blood circulation, or external pressure on the nervous system, which can usually be relieved in a short time. Generally, we do not need to see a doctor.

  Long term hand numbness: be alert

  Unilateral hand numbness

  With dizziness: beware of cerebral infarction

  If the external forces such as extrusion and impact are excluded, one arm suddenly appears numbness and unconsciousness of unknown reasons, one arm soon becomes numb, one face becomes stiff, and at the same time, headache, dizziness, blackness dementia or blurred vision, incoherent speech and poor coordination occur, we must be vigilant.

  This may be caused by transient cerebral ischemia induced by cerebral arteriosclerosis or stenosis, thrombus shedding, and insufficient blood supply, which may indicate high risk diseases such as cerebral infarction in severe cases.

  If these symptoms occur frequently, seek medical attention immediately.

  Inability to align fingers: carpal tunnel syndrome

  Long term excessive play with mobile phones or use of keyboards and mice for office work is likely to lead to carpal tunnel syndrome.

  The disease usually occurs in one side of the palm. Most of the fingers have weakness in moving the wrist. The skin on the palm of the thumb, food finger, middle finger and half ring finger feels stiff, numbness and soreness, and numbness at night increases.

  Serious people can't even complete the "opposite finger" action:

  Self test method: If the wrist is in the maximum flexion position and the thumb, index finger and middle finger feel numb and uncomfortable within 60 seconds, it may be carpal tunnel syndrome.

  Related to sitting posture: cervical spondylosis

  If you are sitting and your hands begin to numb, change the position of your head (cervical vertebra), such as flexing, stretching, lateral bending, or turning your neck, your symptoms will improve. The cause of hand numbness may be cervical spondylosis.

  In clinical practice, nearly 70% of hand numbness symptoms are caused by cervical spondylosis of nerve root type. Due to the degenerative and secondary pathological changes of cervical intervertebral disc, the nerve root is compressed, causing pain in the corresponding nerve distribution area.

  Generally speaking, people with numb thumbs indicate that the sixth cervical nerve root is compressed; The index finger, middle finger and ring finger respectively indicate that the seventh cervical nerve root of the company is compressed; The little finger indicates that the world's eighth cervical nerve root is compressed.

  In addition, patients often have neck and shoulder muscle pain, severe vomiting, dizziness, tinnitus and other symptoms.

  Numbness of hands

  Hands trembling: Parkinson

  Parkinson's disease is a disease of the nervous system, the cause of which is still unclear. It may occur between 40 and 70 years old, and the prevalence is increasing year by year.

  In 80% of patients, tremor starts from the fingers of one hand and gradually spreads to the limbs and body.

  If the abnormal shaking of hands is accompanied by uncoordinated movements, stiff muscles, slow reaction, increased saliva, etc., it is necessary to check whether there is Parkinson's disease in time.

  Feeling of wearing gloves: diabetes

  Bilateral finger numbness is a common clinical symptom of diabetes and peripheral nervous system diseases. The incidence is often symmetrical, similar to the feeling of wearing gloves or socks.

  Many diabetic patients have uncontrolled blood glucose levels and many complications begin early. Therefore, even if the patient has no history of diabetes, long-term hand numbness should also be screened for diabetes.

  Swelling and cooling: cardiovascular disease

  We can know that there are a lot of peripheral nerves and blood vessels on the hand. When the arterial system is narrow and the cardiovascular system is blocked, the hand will also have some corresponding manifestations, such as more and thicker tendons, red, swollen and cool palms, more and deeper information on the palms.

  If sometimes accompanied by chest pain, chest tightness, asthma, dyspnea, arrhythmia, tachycardia and other symptoms, be alert to cardiovascular diseases.

  Habitual alcoholism: alcoholism

  Hand anesthesia may also be a chronic alcoholic peripheral neuropathy.

  If there is no numbness in the hands and feet of people who often drink, it indicates the possibility of treating chronic alcoholism.

  If not intervened in time, it will lead to dysfunction of the body system, even irreversible damage.

  Special period: pregnancy

  Women in menopause sometimes have hand numbness.

  With the end of menopause, hand numbness will gradually disappear.

  Some pregnant women will feel paroxysmal pain and numbness on one side or both hands in the late stage, and have a feeling of acupuncture or burning.

  Pain and numbness mainly affect both sides of the thumb, index finger, middle finger and little finger, resulting in loss of fine motor ability of the fingers, usually without other serious consequences.

  Prevention of hand numbness

  Prevent chronic wrist injuries

  For example, when doing housework and using the mouse for a long time, it is better to have a rest in the middle to relax the muscles, tendons and nervous system of the hand, so as to prevent the stenosis of the carpal canal from compressing the conduction bundle of the neural network and causing hand numbness.

  Pay attention to blood pressure and blood sugar

  The elderly should monitor blood pressure, low salt and low-fat diet to prevent atherosclerosis and thrombosis, improve blood supply to the brain and prevent hand paralysis.

  Regularly monitor your own blood sugar level, and avoid eating too much food with too much sugar in your life, so as to prevent hand numbness caused by diabetic neuropathy.

  Avoid postures

  Avoid keeping a posture for a long time, change the posture in time, and do some neck exercises properly, which can avoid the compression of neck blood vessels and nerves, leading to numbness of hands.

  balanced diet

  Don't be picky, eat more fruits and vegetables, maintain adequate nutrition in the body, and prevent the lack of vitamin B in the body from causing hand numbness.

  In a word, if you can often feel hand numbness, we can not ignore it. You should go to the hospital in time to find the cause and targeted treatment.
