Definition

Finger numbness is an abnormal sensation that’s caused by a change in sensory nerve function.

Alternative Names

Numb fingers, numbness in fingers, numbness of fingers, tingling fingers.

Overview

Sensations are carried to the brain through neurons in the spinal cord. If the blood supply to the nerves is limited or the nerve is otherwise damaged it can produce the feeling that your finger “fell asleep”. Permanent or severe blood loss (ischemia) can result in permanent nerve damage. Nerves in the fingers can be damaged when the blood supply is decreased over time, like in diabetes.

Associated Diagnoses

Treatment will depend on the underlying cause and aim to relieve symptoms. Physical and occupational therapy and stretching exercises may help ease symptoms once the underlying cause is found and treated.
