Causes

By Mayo Clinic Staff

Hand numbness can be caused by damage, irritation, or compression of a nerve or a branch of a nerve in your arm and wrist.

Diseases affecting the peripheral nerves, such as diabetes, also can cause numbness. However, diabetes usually causes numbness in the feet first.

Uncommonly, numbness may be caused by problems in your brain or spinal cord. When this happens, arm or hand weakness or loss of function also occurs. Numbness alone isn't usually associated with potentially dangerous disorders, such as strokes or tumors.

Your doctor needs detailed information about your symptoms to diagnose the cause of numbness. A variety of tests may be needed to confirm the cause before treatment can begin.

Brain and nervous system conditions

  1. Cervical spondylosis
