Finger numbness usually arises from a lack of blood supply to an area or damage to a nerve or nerves that supply the hand, such as in carpal tunnel syndrome or a cervical disk problem. Finger numbness can also result from infection, inflammation, trauma, and other abnormal processes. Most cases of finger numbness are not due to life-threatening disorders, but it does occur with stroke and tumors.
Depending on the cause, the loss of sensation can disappear quickly, such as numbness from sleeping with your elbow and wrist bent that fades away once you move your arm around. Chronically numb fingers can be due to diabetes, multiple sclerosis, or peripheral neuropathy. Chronic finger numbness generally indicates some level of damage to the nerves.
Pinky and ring finger numbness on the back and palm side of the hand can be a sign of ulnar nerve compression in the arm. Numbness of the thumb, index, middle, and half of the ring finger may be caused by carpal tunnel syndrome.
