What is whole body paralysis? What causes numbness in hands?

We often hear that someone goes to the hospital because of numbness in the hands and is diagnosed with cervical spondylosis. So once numbness in the hands occurs, people will think about whether they have cervical spondylosis. In fact, this is not the case. There are many reasons for numbness in the hands. So what else causes numbness in the hands?

1. Blood vessel factors: When we sit for a long time or sit in a bad posture, it will cause numbness in the lower limbs. When the hands are placed in the wrong posture, they will also feel numb. Once you relax, it will feel like thousands of ants are crawling.) Because when the blood vessels are compressed, the blood vessels supply part of the limbs is ischemic, causing numbness. When the compression is relieved and blood flows through, it will feel like many ants are crawling. As shown in the figure, when the ulnar artery and radial artery of the upper limb are compressed at a certain point, it will cause numbness in the hands.

2. Nerve factors: There is axoplasm flowing in the nerves. When the nerves are compressed, the axoplasm flow is blocked, which can also cause numbness in the hands. As shown in the figure: There are mainly radial nerves, ulnar nerves, and median nerves to the palms. These nerves start from the cervical canal, pass through joints, ligaments, and bone fiber tubes to reach the ends of the palms. In any part, if the nerves are compressed, it will cause numbness in the hands.

3. Brain factors: All nerves originate from the brain. When there is a problem with the brain, such as a stroke, the area controlled by the brain will become numb and weak.

4. Systemic factors: Some systemic diseases such as: A. Hyperlipidemia: Long-term hyperlipidemia can easily lead to sclerosis of blood vessel walls. In addition, hyperlipidemia makes blood thicker, blood flow slows down, and the amount of oxygen and nutrients available to cells decreases, leading to numbness. B. Diabetics: Blood sugar levels remain high, which, over time, can cause great damage to blood vessels and nerves, leading to vascular sclerosis and nerve degeneration.
