What Are Pins and Needles?
Pins and needles — medically known as paraesthesia — is a sensation of tingling, prickling, or numbness in the hands (or other body parts). Most people are familiar with the temporary "pins and needles" feeling after sitting in an awkward position that briefly cuts off blood supply or presses on a nerve. However, persistent or recurring pins and needles in the hands can indicate an underlying condition that needs assessment.
Common Causes
- Carpal tunnel syndrome — the most common cause of pins and needles in the hands
- Cervical radiculopathy — a pinched nerve in the neck
- Cubital tunnel syndrome — ulnar nerve compression at the elbow
- Peripheral neuropathy — nerve damage, often from diabetes
- Raynaud's phenomenon
- Vitamin B12 deficiency
- Thoracic outlet syndrome
- Multiple sclerosis (rarely)
Which Fingers Are Affected?
The pattern of pins and needles can help identify the cause:
- Thumb, index, middle, and half of ring finger — carpal tunnel syndrome (median nerve)
- Ring and little finger — cubital tunnel syndrome (ulnar nerve)
- Whole hand — cervical radiculopathy or peripheral neuropathy
When to See a Doctor
See your GP if pins and needles in the hands are persistent, progressive, associated with weakness or loss of grip, or accompanied by other symptoms such as neck pain, visual changes, or balance problems.
