হাত-পা অবশ বা ঝিনঝিন: কারণ ও করণীয়

Occasional "pins and needles" — like when your foot falls asleep — is normal. But numbness or tingling that keeps coming back, or doesn't go away, can point to a nerve problem worth investigating.

Common causes

A pinched nerve in the neck or lower back, carpal tunnel syndrome (wrist), diabetes-related nerve damage, vitamin deficiency, or pressure on a nerve from a disc or tumor.

See a doctor if you have

• Numbness that spreads or persists
• Weakness, clumsiness, or dropping objects
• Numbness with neck or back pain
• Symptoms after an injury

Treatment depends on the cause and ranges from physiotherapy and medication to a nerve block or, in some cases, surgery to relieve pressure on the nerve.
