summary

In daily life, if people lie on the table for a nap, the pressed hand is prone to numbness. However, the frequent numbness of the hand is related to some factors. Next, we will analyze the causes of the frequent numbness of the hand.

What causes hand arthralgia

One of the reasons: vascular factors. When we sit for a long time or the posture is not good, it will cause numbness in the lower limbs. When we put our hands in the wrong posture, it will also cause numbness. If we relax, it will be like tens of millions of ants crawling. Because when the blood vessels are compressed, the blood supply to the limbs is ischemic, causing numbness. When the compression is relieved, the blood flows past, it will feel like there are many ants crawling, If the radial artery tube is pressed in a certain place, it will cause hand numbness.

The second reason: nervous factors. There is axoplasmic flow in the nerve. When the nerve is compressed, the axoplasmic flow is blocked, which will also cause hand numbness. As shown in the figure, there are radial nerve, ulnar nerve and median nerve in the palm. These nerves start from cervical spinal canal, pass through joints, ligaments and bone fiber tubes, and reach the end of the palm. In any part, nerve compression will cause hand numbness.

The third reason: brain factor. Generally speaking, the sensation of hand numbness is transmitted through nerves, and the brain is the source of all nerves. Therefore, when people have certain problems in the brain, such as stroke, numbness and weakness will appear in the areas dominated by the brain.
