Hand numbness is usually caused by damage, irritation or compression of one of the nerves or a branch of one of the nerves in your arm and wrist. Diseases affecting the peripheral nerves, such as diabetes, also can cause numbness, although with diabetes similar symptoms usually occur first in your feet. In very uncommon instances, numbness can be caused by problems in your brain or spinal cord, although in such cases arm or hand weakness or loss of function also occurs. Numbness alone is only rarely associated with potentially life-threatening disorders, such as strokes or tumors.
Hand Numbness and Tingling, by David Katz, MD. Do your hands ever go numb and tingly? Do you wake up at night with a âdeadâ hand and have to shake it out to get it to âwake up?â Do your hands fall asleep while driving a car or holding a cell phone? If so, then you may have increased pressure on a nerve in your palm â a condition called Carpal Tunnel Syndrome. Carpal Tunnel Syndrome (CTS) is the most common cause of numbness and tingling in the hand. As a result of pressure on the median nerve, one may experience pain, weakness, and numbness in the hand and fingers. This typically affects some combination of the thumb, index, middle, and ring finger.
