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.
Smoking and working with vibrating machinery increases the risk of developing Raynaud's syndrome. As the blood vessels leading to the fingers and toes spasm, they become narrower, decreasing the supply of blood and oxygen to the area. This causes the fingers to turn white and feel numb or tingling. Although rare, a severe case can cause the arteries to permanently narrow or become blocked, leading to deformities of the fingers due to lack of blood.
