The numbness of the left hand is first considered to be cerebrovascular disease, due to the lack of blood or blockage of the cerebrovascular system, the patient may have a loss of brain function, manifested as numbness and weakness of the limbs.

Question 1: What is the cause of numbness in my hands? In daily life, many people have encountered the problem of numbness in their hands.

What's the deal with frequent numbness in my hands? The vast majority of people may ignore the seriousness of the problem, thinking that the numbness in the hands is just a minor problem, and it will be over after a while. In fact, frequent numbness in the hands may not simply be a wrist problem, and you need to find the culprit from the root.

So, what is the reason for frequent numbness in the hands, there are five main reasons for the common ones:

1.Menopausal syndrome.

The numbness in the hands caused by menopausal syndrome is generally not noticeable, and the symptoms gradually disappear as the menopause ends.

2.Cervical spondylosis.

Frequent numbness in the hands may be related to cervical spine problems, which can lead to numbness in the hands when cervical spondylosis causes compression of adjacent nerve roots.

3.Upper extremity nerves are entrapded.

First, there is a history of numbness and pain in the thumb, index and middle finger before the wheel, and there is often a history of nocturnal numbness, which can improve after waking up and moving, which is called "carpal tunnel syndrome"; The second is numbness and pain in the ring finger and little finger, which is the so-called "cubital tunnel syndrome".

4.Peripheral neuritis.

If the long-term digestion and absorption function is poor and malnutrition, it will lead to vitamin B1 deficiency and peripheral neuritis, and it will also cause numbness in the hands.

5.Stroke People who have had a stroke often experience symptoms such as headaches, dizziness, numbness in the limbs, and swollen tongues.

Finally, experts warn that frequent numbness in the hands should not be taken lightly, because it is likely to be a sign of certain diseases. Therefore, if you often have the problem of numbness in your hands, you should consult a professional doctor as soon as possible to find out the root cause, and then treat the symptoms** to completely eliminate the symptoms of numbness in your hands.

There are many reasons for numbness in the fingers, so let's **** with me.

Causes of numbness in the fingers:

1. Upper limb nerve entrapment: First, numbness and pain in the thumb, index and middle finger, often with a history of awakening at night, and the activity can be improved after waking up. In severe cases, it can be accompanied by atrophy of hand muscles, affecting the fine movements of the hand, because the median nerve is compressed in the wrist, the so-called "carpal tunnel syndrome"; The second is the numbness and pain of the ring and little finger, and there can also be a history of awakening at night, and in severe cases, it is accompanied by muscle atrophy, and the flexion force of the ring and little finger decreases, which affects the fine use.

This is because the nerve is entrapped in the elbow, the so-called "cubital tunnel syndrome".

2. Cervical spondylosis: The most common disease that causes hand numbness is cervical spondylosis, which is one of the most common diseases in middle-aged and elderly people. When people enter middle age, some organs tend to degenerate, when the cervical intervertebral disc degenerates, it often leads to cervical disc herniation or joint sudden hyperplasia or hypertrophy, these herniated cervical intervertebral discs or hypertrophic articular processes once compress the adjacent cervical nerve roots, cervical spondylosis occurs.

In addition to numbness and paresthesia in the fingers, cervical spondylosis is also accompanied by other symptoms, such as: pain in the neck and shoulder, radiating pain or mobility disorders in the upper limbs. It is not difficult to diagnose cervical spondylosis, as long as an X-ray is taken.

In addition, there is a simple way to check cervical spondylosis, a person holds the head of the affected side, holds the upper limb of the affected side with one hand, abducts it 90 degrees, and pushes and pulls both hands in the opposite direction at the same time.

3. Stroke: Another common disease that causes hand numbness is stroke. "Hygiene Treasure Stroke" once said:

Mortals who are numb or insensitive to the first finger or the second finger will have a stroke within three years. "It must be prevented: it is advisable to live cautiously, eat sparingly, be far away, and be ambitious.

Although numbness of the fingers does not necessarily cause stroke, for middle-aged people over the age of 40, if they often have symptoms such as headache, dizziness, lightheadedness, numbness of limbs, and swollen tongue, and the patient usually has hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis and other diseases, they should pay more attention and be alert to the occurrence of stroke.

4. Menopausal syndrome: women who enter menopause sometimes have hand numbness, but it is not obvious, and with the end of menopause, hand numbness will disappear.

5. From an anatomical point of view, sensory impairment. In patients with cervical radiculopathy, the two often coexist, i.e., numbness of the fingers and decreased grip strength. It is only because of the high sensitivity of sensory nerve fibers that numbness in the fingers manifests earlier in the symptoms.

Cervical spondylosis compresses the nerves like this Cervical spine problems are common diseases, most of them do not need drugs or surgery**, find an osteopathic doctor, their techniques are dedicated to treating this kind of disease, no longer compressing the nerves, and the corresponding symptoms will naturally disappear, that is, there will be a little skin pain when treating, just take a break, ** time does not exceed ten minutes, usually do not maintain a posture for a long time, do not sleep on a soft bed.
