Why Does a Part of My Hand Feel Numb?

The phenomenon of numbness in the body is common in daily life, and it is generally caused by prolonged local compression. Appropriate activities can gradually restore the sensation. However, numbness in the back of the hand is often caused by cubital tunnel syndrome, carpal tunnel syndrome, cervical spondylosis, cerebrovascular disease, and diabetic peripheral neuropathy. Some people experience repeated numbness in certain areas, which requires attention as it is often caused by underlying diseases. It is necessary to actively seek the cause and find a solution.

Numbness in the back of the hand is most commonly seen in injuries to the ulnar nerve, radial nerve, and median nerve, which are often associated with cubital tunnel syndrome, carpal tunnel syndrome, and cervical spondylosis. After peripheral nerve damage, it can lead to reduced sensation in the back of the hand. By nourishing the nerves and reducing edema of the nerve roots, the symptoms can be alleviated. Additionally, cerebrovascular diseases can also cause numbness in the back of the hand due to embolisms caused by vascular plaque narrowing, leading to ischemia and hypoxia in the hand or brain. Diseases in the brain can also compress or stimulate nerve tissue, causing certain obstacles in the control of muscles by the nerves, resulting in numbness in the back of the hand. By improving circulation, nourishing the nerves, antiplatelet aggregation, lipid regulation, and stabilizing plaques, the symptoms can be alleviated. Finally, diabetic peripheral neuropathy can also cause inflammation of the peripheral nerves, affecting the perception of the body and leading to numbness in the back of the hand. Symptoms can be alleviated through hypoglycemic treatment and nourishment of the peripheral nerves.
