Why do patients with cervical spondylosis often experience numbness in their fingers?
Disease description:
My colleague's cervical spondylosis is not very severe, but his fingers often feel numb. I'm not sure if this is caused by cervical spondylosis. I'd like to know why patients with cervical spondylosis frequently experience finger numbness.

Patients with cervical spondylosis often experience numbness in their fingers because there is a sensory receptor in the fingers. When the fingers touch something hot or cold, the sensation travels through nerves—like electrical wires—to the brain. A herniated disc in the neck can obstruct this signal transmission, causing the signals to become disrupted. As a result, patients may feel numbness, dullness, and reduced finger dexterity.
