Finger numbness is an abnormal sensation thatâs caused by a change in

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