Causes of Numbness in Fingers. Carpal tunnel syndrome: damage to the nerves in the arm can cause the fingers to become numb or experience a tingling sensation. A common cause of this nerve damage is carpal tunnel syndrome, a condition that causes a nerve to become pinched between the ulna and radius in the arm.
Carpal tunnel and tendonitis can both cause numbness tingling and pain in the lower arm hands and fingers. Although they have similarities they are caused by different things. Carpal is caused when a nerve is pinched from soft tissue, bone, tumor, muscle or inflammation.
