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.
One possible cause of numbness in the finger tips is lack of blood flow. This can be caused by something called Raynaud's phenomenon. Raynaud's phenomenon is a symptom that is seen in some disease such as lupus where blood flow doesn't reach the tips of the fingers, especially in cold weather. Another common cause of numbness in the finger tips is uncontrolled diabetes. High blood sugars caused by diabetes damage nerves in the finger tips and toes. If you also have nerve problems in your feet, then this could be an explanation. I suggest that you schedule an appointment with your primary care physician.
