What Is Numbness & Tingling?

Numbness is a loss of sensation, while tingling is a "pins and needles" feeling. These sensations can occur anywhere in the body but most commonly affect the hands, feet, arms, and legs. Temporary numbness from sitting in one position is normal, but persistent or recurring symptoms should be evaluated.

Common Causes of Numbness & Tingling

• Compressed nerve (carpal tunnel, sciatica)
• Poor circulation
• Vitamin B12 deficiency
• Diabetes (peripheral neuropathy)

• Sitting or sleeping in one position

When to See a Doctor

See a doctor if numbness or tingling is persistent, worsening, affects one side of the body, or follows an injury. Seek emergency care if it comes with sudden weakness, confusion, severe headache, or difficulty speaking.
