Numbness and Tingling in Hands and Feet: What It Could Mean

Many people feel their hands or feet 'go to sleep' occasionally, and that is usually harmless. But when it happens often or lasts long, it may point to a nerve issue that deserves attention. Let's understand the common reasons.

Common causes

• Sitting or sleeping in one position too long
• Vitamin B12 or folate deficiency
• Diabetes affecting peripheral nerves
• Nerve compression, such as in carpal tunnel
• Poor blood circulation

When it's more than temporary

• Numbness that returns daily without an obvious cause
• Tingling spreading from fingers or toes upward
• Accompanied by weakness or clumsiness
• Occurring on one side of the body only

What a neurologist may check

• Blood sugar and vitamin B12 levels
• Nerve conduction study if needed
• Thyroid function tests
• Detailed physical and reflex examination

Most causes of numbness are treatable once identified correctly.
