Your Hands and Feet Are Tingling. Here's Why

Have your hands or feet ever gone numb or started tingling for no apparent reason?

Maybe your fingers feel like they're buzzing, your toes feel asleep, or you experience that strange pins-and-needles sensation.

It happens to many people, especially as we get older. And while it isn't always something serious, sometimes it's your body's way of telling you something isn't right.

So when should you worry?

Let's start with the good news.

If your foot falls asleep after sitting too long or your hand tingles after sleeping in an awkward position, it's usually nothing to worry about. Changing positions typically relieves the pressure, and the sensation disappears within minutes.

But what if the numbness keeps coming back?

Or what if your fingers and toes seem to be tingling more often than they used to?

There are several possible reasons.

1. Diabetes could be affecting your nerves.

Diabetes is one of the most common causes of nerve damage. This condition, called diabetic neuropathy, often starts in the feet.

You might notice burning, tingling or numbness in both feet. Some people describe it as wearing invisible socks or gloves.

2. You could have a pinched nerve.

As we age, changes in the spine can put pressure on nerves. Conditions such as spinal stenosis and carpal tunnel syndrome can also cause numbness and tingling.

You may notice symptoms in your hands, arms, legs or feet.

3. Your body could be missing important vitamins.

Certain vitamin deficiencies, particularly involving vitamin B12, can contribute to nerve problems.

Kidney disease, alcohol use and some medications, including certain chemotherapy drugs, can also affect nerve function.

4. Stress and anxiety may play a role.

Believe it or not, stress can cause tingling sensations, particularly around your mouth and in your hands.

Rapid breathing during periods of anxiety can trigger these symptoms.

So when should you see your doctor?

Don't ignore numbness or tingling that:

Keeps happening or becomes constant.

Gets worse over time.

Makes everyday activities difficult.

Comes with pain, muscle weakness or balance problems.

Makes walking difficult.

Your healthcare provider may recommend blood tests, imaging or nerve studies to help identify what's causing the problem.

Treatment depends on the cause. It might involve medication, physical therapy, improving blood sugar control or addressing pressure on a nerve.

But here's something you should never ignore.

If you suddenly experience numbness on one side of your face, arm or leg, it could be a sign of a stroke.

Especially if you also have weakness, trouble speaking or other sudden neurological symptoms.

Call 911 immediately. Don't wait to see if it goes away.

Sudden numbness around the groin, particularly with bladder or bowel problems or leg weakness, also requires emergency medical attention.

Here's the bottom line:

Occasional tingling after sitting or sleeping in an awkward position is usually harmless.

But persistent numbness, worsening symptoms or unexplained weakness deserve attention.

As we get older, it's important to listen to our bodies. Don't assume every new symptom is simply part of aging.

Sometimes getting checked early can make a big difference.
