One day, Aunt Qi was playing mahjong with her neighbors in the community as usual. Suddenly, she felt numb in her left hand and left leg, unconscious, unable to exert any strength, unable to sit still and leaning to one side.

When the neighbors saw it, they were frightened and quickly sent Aunt Qi to the Stroke Center of the First Hospital of Zhejiang University. After a preliminary examination, the doctor found that Aunt Qi suffered from hemiplegia and mild hemiplegia. I learned that Aunt Qi had a history of stroke. After taking aspirin and statins, the doctor suspected that Aunt Qi was a cerebral infarction.

Finally, the results of brain CT examination showed that Aunt Qi's small blood vessels were blocked and gradually returned to normal after intravenous thrombolysis.

You must have had such an experience: taking a nap with your arm resting in the office and waking up with numbness in your arm; After squatting for more than half an hour, my feet are numb ... This physiological numbness is caused by poor posture or external pressure, which can return to normal in a short time.

But if there is a long-term numbness in one hand and one foot, or intermittent numbness in the fingers, or even wake up in the middle of the night due to numbness, you should be alert, which may be caused by disease!

1 carpal tunnel syndrome

Trauma, strain and other oppression of the median nerve can cause numbness, tingling and pain. Carpal tunnel syndrome is common in women aged 30-50, mainly manifested as numbness and pain in thumb, index finger and middle finger, which is improved after moving joints. Carpal tunnel syndrome is most likely caused by using the mouse or keyboard for a long time, or stretching the wrist repeatedly for a long time.

2. Cerebral ischemia/stroke

Hand numbness is one of the typical symptoms of cerebral ischemia and stroke, which is common in middle-aged and elderly people. Mainly caused by hypertension, hypertension, diabetes and other diseases, such as cerebral atherosclerosis, thrombosis, cerebral blood supply deficiency, transient cerebral hemorrhage, numbness of one limb, dizziness, headache, dizziness and other symptoms.

3. Peripheral neuropathy

Peripheral neuropathy refers to a disease that damages the nervous structure or function of the peripheral nervous system, which is related to infection, drugs, immunity, heredity, tumor, trauma and other factors. Studies have also shown that it is mainly caused by vitamin B deficiency, and the synthesis of nuclear protein and myelination of human body are inseparable from vitamin B. The symptoms of peripheral neuropathy are mainly manifested as abnormal sensation, burning pain, tingling and numbness of limbs, and diabetes can also cause peripheral neuropathy.

4. Cervical spondylosis

Cervical spondylotic radiculopathy is the most common symptom of hand anesthesia. The data show that the proportion of hand anesthesia caused by cervical spondylotic radiculopathy is as high as 70%. In daily life, improper sitting posture, long-term bowing, sedentary and improper pillow height may all lead to cervical spondylosis.

In addition to hand numbness, there may be symptoms of shoulder and neck muscle pain, and even dizziness and vomiting in severe cases.

5. Climacteric syndrome

"Menopause" syndrome can also lead to hand numbness, which is unexpected by many people.

On the one hand, due to the decrease of calcium absorption and the increase of calcium loss in menopause, there are signs of low calcium, which eventually leads to numbness. On the other hand, the ovarian function gradually declines, and the autonomic nervous system appears disorder, thus causing hand numbness. With the end of menopause, hand numbness will be relieved until it disappears.

In addition, hand numbness may also be related to diabetes, hypertension, rheumatoid arthritis, bone marrow diseases, multiple sclerosis, poisoning and other factors, so we need to be vigilant.

When hand numbness occurs, it is not only inconvenient to do things, but also the feeling of "ant bite", which makes people very uncomfortable. In severe cases, people may even stay up all night because their hands are numb, which will affect their normal life. Then, whether it is physiological hand numbness or pathological hand numbness, how should you relieve it when you are uncomfortable?

We suggest that we can try the action of "YTWL".

First, stand naturally, with your feet 60 apart, your knees slightly bent, your feet motionless, and your hips moving backwards, and then do the actions in the order of "YTWL".

Take "t" as an example. When the arm straightens at 90 degrees to the trunk, the thumbs of the left and right hands straighten backwards, then the arm is forced in the direction of thumb straightness, slowly lifted, held for 1-2 seconds, and then slowly lowered.

"YWL" can be executed with reference to the action essentials of "T". Do it three times a day, and do three groups each time, each group 10- 15. You can rest properly according to your personal situation, stick to it, exercise your wrists and fingers, and prevent and relieve hand numbness. If you don't like standing, you can also lie prone or semi-prone.

A little numbness in the hand is a serious illness. If it is physiological hand numbness, it is easy to distinguish it from pathological hand numbness. Physiological hand anesthesia has little effect and can recover on its own. If you have pathological numbness in your hands, you must seek medical attention in time to avoid more serious consequences.
