The Common Vitamin Deficiency in Numb Hands and Pins and Needles

Hand numbness can be 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.
