What is the cause of hand numbness 5, what is the cause of hand numbness

1.Vascular factors:

When we sit for a long time or sit in a bad posture, it will cause numbness in the lower limbs, and when the hand is not in the right position, it will also be numb, and when we relax, it will be like thousands of ants crawling. Because when the blood vessels are compressed, the blood vessels ** limbs are partially ischemia, causing numbness, and the compression is relieved later, and the blood flows.

2.Neurological factors:

There is axoplasmic flow in the nerve, and when the nerve is compressed, the axial plasma flow is obstructed, which can also cause numbness in the hand. As shown in the figure: to the palm there are mainly radial nerves, ulnar nerves, median nerves, these nerves start from the cervical spinal canal, pass through the joints, ligaments, fibrous canals to the end of the palm, in any.

If a nerve is compressed in one area, it will cause numbness in the hand.

3.Brain Factor:

All nerves are in the brain, when there is a problem in the brain. In the case of a stroke, numbness and weakness occur in the area dominated by the brain.

4.Systemic factors:

Some systemic diseases such as:

a.High blood lipids: Long-term high blood lipids can easily cause hardening of blood vessel walls, coupled with high blood lipids, blood viscosity, blood flow slows down, and cells receive less oxygen nutrients, resulting in numbness.

b.Diabetics: Maintaining a high level of blood sugar for a long time will cause great damage to the body's blood vessels, nerves, arteriosclerosis, and neurodegeneration.

However, it is still recommended that you go to the hospital for a check-up or ask the official ** of numbness in your fingers.

From the perspective of traditional Chinese medicine, hemp is the blockage of qi and blood in the meridians, such as a precursor to stroke; There is also cervical spondylosis, which can also cause numbness. Massage can dredge the meridians, with some Chinese medicine to dredge the meridians.

It is recommended that you go to the hospital for cervical spine CT and you will know that it is cervical disc disease (spinal cord trunk type).

The most common causes of hand numbness are as follows:

1. Upper limb nerve entrapment

1) It is numbness and pain in the thumb, index and middle finger, and there is often 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, which affects the fine motor skills of the hand, because the median nerve is compressed in the wrist, which is the so-called "carpal tunnel syndrome";

2) It is numbness and pain of the ring and little finger, and there may 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, affecting fine movements. 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. In addition to numbness and paresthesia in the fingers, cervical spondylosis is accompanied by other symptoms, such as: neck and shoulder muscle soreness, radiating pain in the upper limbs or mobility disorders.

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 for cervical spondylosis, a person holds the head of the affected side, holds the upper limb of the affected side with one hand, abducts it by 90°, and pushes and pulls both hands in the opposite direction at the same time.

3 Stroke: Another common condition that causes numbness in the hands is stroke. If symptoms such as headache, dizziness, lightheadedness, numbness of limbs, and swollen tongue often occur, and patients usually have hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis and other diseases, they should pay more attention and be alert to the occurrence of stroke.

In short, the diagnosis of hand numbness symptoms requires reference to cervical spine radiograph, electromyography and other auxiliary examinations to confirm the diagnosis. If the symptoms are obvious and there is obvious atrophy of the inner muscles of the hand, surgery should be taken in time to prevent the development of the disease, so as not to cause irreversible severe atrophy of the intrinsic muscles of the hand, resulting in serious dysfunction of the hand.

This numbness in the hands really needs our attention, in addition to the possibility of stroke, but also because of cervical spondylosis.

What's wrong with frequent numbness? It is roughly related to 4 situations, and you may wish to compare it with self-testing.

Hand numbness is also a variety of reasons can cause hand numbness, specifically divided into a central cause, a peripheral nerve cause, and then an internal medicine caused by hand numbness, specific central causes including cerebrovascular accident, brain tumors can cause these symptoms of hand numbness, but generally these will be accompanied by some other hemiplegic limb weakness, hemilimb sensory impairment, peripheral hand numbness includes some cervical spine, cervical spondylosis, hand numbness caused by compression of the neck nerve, and some local ulnar nerve, Hand numbness caused by radial nerve, median nerve, peripheral nerve, and some internal medicine disease systems, such as hand numbness caused by diabetes, there are some differences between this hand numbness and hand numbness in the peripheral nervous system just now, and some hand numbness belongs to a peripheral neuropathy, mainly including some diabetes, drug poisoning, and heavy metal poisoning can cause these hand numbness symptoms, mainly sock-like changes, and then symmetry.

What's wrong with frequent numbness? It is roughly related to 4 situations, and you may wish to compare it with self-testing.

Be careful with frequent hand numbness, it may be that there are these 3 kinds of problems on the body, and they should be adjusted in time.

Caused by poor blood circulation in the arm.
