Introduction
Numbness in both hands may be caused by physiological factors, or conditions such as carpal tunnel syndrome and cervical spondylosis. The hands contain numerous sensory nerves that connect to the cerebral cortex and spinal cord. When cervical spondylosis occurs, nerve roots can become compressed, leading to pressure on the sensory nerves controlling the hands and resulting in numbness. In addition to these causes, bilateral hand numbness may also be due to peripheral neuritis.
Hand numbness may be caused by physiological factors, or it could result from conditions such as carpal tunnel syndrome or cervical spondylosis. A detailed analysis is as follows:
I. Physiological Factors
If one engages in prolonged housework, physical labor, or extended periods of playing badminton or tennis, overexertion may easily occur, leading to hand numbness. In such cases, adequate rest is usually sufficient, and there is no need for excessive concern.
II. Pathological Factors
1. Carpal Tunnel Syndrome
When suffering from carpal tunnel syndrome, the median nerve may become compressed within the narrowed carpal tunnel, resulting in symptoms such as hand numbness. Symptoms often worsen at night or in the early morning hours, but can be relieved by gently shaking or moving the wrists.
2. Cervical Spondylosis
The hands contain numerous sensory nerves connected to the cerebral cortex and spinal cord. When cervical spondylosis develops, nerve roots may become compressed, affecting the sensory nerves that control the hands and causing numbness in both hands. Under a doctor's guidance, neurotrophic medications such as mecobalamin tablets or vitamin B1 may be taken appropriately.
In addition to the above causes, bilateral hand numbness may also stem from conditions such as peripheral neuritis or peripheral nerve disorders. It is recommended to seek timely medical evaluation to identify the underlying cause and avoid delays in treatment. Treatment options may include general supportive care, physical therapy, and medication.
