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.
Your doctor will need detailed information about your symptoms to diagnose the cause of your numbness. A variety of tests may be needed to confirm the cause before appropriate treatment can begin.
Possible causes of numbness in one or both of your hands include:
Brain and nervous system conditions
- Cervical spondylosis
- Guillain-Barre syndrome
- Paraneoplastic syndromes of the nervous system
- Peripheral neuropathy
- Spinal cord injury
Trauma or overuse injuries
- Brachial plexus injury
- Carpal tunnel syndrome
- Cubital tunnel syndrome
- Lyme disease
