1, cause analysis
(1) When the finger peripheral nerve lacks vitamin B, it will cause inflammation and numbness of the finger.
(2) When trauma or tumor affects the ulnar nerve of the arm, it will cause finger numbness.
(3) Numbness of fingers may also be caused by cervical spondylosis. The appearance of cervical spondylosis is usually due to cervical hypertrophy and hyperplasia or cervical disc herniation, which compresses the cervical nerve and numbs the fingers.
2. Main dangers
Finger numbness is an independent motor nerve injury disease of limbs, which is mostly caused by stroke, hemiplegia, diabetes, neuritis, cervical spondylosis and lumbar spondylosis. The tiny blood vessels around the motor nerve fibers are blocked, which compresses the motor fibers, resulting in serious damage to the motor nerve fibers, decreased nerve conduction ability and conduction speed, and numbness of hands and feet. Severe cases can develop into painful symptoms, such as quadriplegia and muscle atrophy.
3. Symptomatic treatment
(1) If there is vitamin deficiency, patients should supplement vitamin B appropriately. Can be supplemented by food, such as eating bananas, carrots, spinach, mushrooms and other foods rich in B vitamins, you can also take Jinaoli brand B vitamins.
(2) Many patients will recover after a period of nerve injury, and some patients can't recover and need surgery, such as removing tumors.
(3) If it is caused by cervical spondylosis, it is still necessary to pay attention to the recovery of this situation. First of all, you should pay attention to rest, don't sit for a long time, exercise more, and then take medicine.
4. Preventive measures
(1) Use both hands as much as possible. According to the theory that the left brain dominates the right side of the body and the right brain dominates the left side of the body, it is always that one hand can only stimulate the brain that dominates the hand. People with left brain advantage should strengthen the use of left hand and left body, stimulate the potential of right brain, balance the relationship between left and right brain, and make it develop harmoniously. Therefore, people who like to use their right hands should exercise their left hands more, such as lifting things with their left hands, closing doors and windows, turning pages, practicing writing, drawing and working with their left hands. Left-handers should exercise their right hands.
(2) Cultivate the flexibility of fingers. Fingertips should be able to engage in some precise activities, such as assembling small plastic models, playing with small toys and sharpening pencils with knives.
(3) Enhance the flexibility of critical section. This is conducive to improving the efficiency of the brain. Such as reaching your fingers, hanging your elbows to write and draw, knitting sweaters, etc.
(4) Exercise skin sensitivity. Insensitive skin touch means that the sensory center of the brain is dull, so always let your fingers receive hot and cold stimulation, such as washing your hands with cold water and hot water.
(5) finger movements are diversified. Always monotonous methods will reduce the flexibility of fingers and limit the information transmission between the brain and fingers. Can carry out various forms of finger activities, if necessary, you can also use fitness balls to move your fingers.
