When neck pain comes with tingling down the arm, it's a different story

Where it hurts and where the problem is can be different places

Key points in 30 seconds

1. Tingling is a signal from the wiring. When a nerve coming out of the neck gets pinched, the signal shows up not where it's pinched but at the far end the wire reaches: the arm and fingers.
2. So if you only rub your hand, you'll miss the cause. It's like only changing the bulb when the desk lamp flickers.
3. There are three clues you can gauge at home: which fingers tingle, whether it changes when you move your neck, and whether it's tingling or weakness.
4. But these clues are guesses, not a diagnosis. Sometimes two places are pinched at the same time.
5. If weakness keeps getting worse, you're getting clumsy with chopsticks, or you're unsteady on your feet, don't bother gauging; a thorough check comes first.

What we often hear

• "At first I thought it was a circulation problem."
• "I thought I'd slept on my arm, but it's been weeks."
• "There's a zinging line running down the outside of my arm."
• "My neck's a bit stiff, but the problem seems to be more my arm than my neck."

Your hand tingles, so you shake out your wrist and keep rubbing your arm. Here's what I want to tell you today.

Where it hurts and where the problem is can be different places.

Tingling is a signal from the wiring

The nerves coming out of the neck run like wires through the shoulder and arm, all the way down to the fingertips.

When one of these wires gets pinched somewhere, the signal shows up not where it's pinched but at the far end the wire reaches. Even when the pinch is in the neck, the tingling is felt in the arm and fingers.

So if you only look at the hand, you'll miss the cause. It's like only changing the bulb when the desk lamp flickers, when the problem is in the cord.

Three clues to gauge at home

One: draw a map of the tingling.

Which fingers tingle is a clue. The thumb side, the little-finger side, or the whole hand?

The common problem of a pinch at the wrist rarely involves the little finger, and it often gets worse at night and briefly better when you shake out your hand. On the other hand, when the pinch is in the neck, the tingling often runs not just to the fingers but along a line up into the forearm and shoulder.

Two: see whether your arm symptoms change with your neck position.

If the tingling in your arm gets worse when you tilt your head back or turn it toward the painful side, that's a clue pointing to the neck. Some people, on the other hand, feel relief when they rest the hand of the tingling side on top of their head.

Three: tell apart tingling and weakness.

Odd sensations and weakness carry different weight. If you keep dropping things, can't open a bottle cap, or your arm lacks strength when you lift it, that's a signal one step above tingling.

But these are guesses, not a diagnosis

In reality, sometimes two places are pinched at the same time, and a shoulder problem can also show up as arm pain. How the same thing happens with the shoulder is covered separately.

Because this fork in the road completely decides the direction of treatment, the check is done through an exam and, when needed, imaging.

At your first visit, we check the map of your tingling and your strength, sensation and reflexes through an exam, and if a pinched nerve in the neck is suspected, we check together with the radiology clinic on the 2nd floor of the same building before deciding on a direction.

With these signs, don't bother gauging; getting checked comes first

• Weakness keeps getting worse. This month is weaker than last month
• Using chopsticks, buttoning clothes or writing has become clumsy in a way it never was
• You're unsteady on your feet, or your legs feel stiff too
• There's been a change in your bladder or bowel control

Changes in fine hand movements and even in walking can be a sign of a problem closer to the center of the nervous system.

In these cases, it's not the stage to discuss Korean medicine treatment; a thorough evaluation comes first. If you come to us, we'll give you the same answer and refer you right away.

What comes after the check

Even when a pinched nerve in the neck is confirmed, it's known that in many cases without the signs above, it gets better over time.

So our role is twofold.

One is to work on pain and tension in the neck and shoulders with acupuncture, pharmacopuncture and Chuna, to make that time of recovery bearable.

The other is to recheck your strength and sensation at set points, so that if signs of progression appear, we don't miss them and send you on to the next step.

Watching whether it gets better is part of care, but catching it early when it gets worse is an even more important part of care. The order in which we look at the neck is laid out in our neck care page.

One thing to do this evening

A night when you fall asleep without rubbing your arm. A hand that doesn't hesitate in front of a bottle cap. That everyday life is what we aim for.

Progress varies from person to person, depending on where and how badly the nerve is pinched, and how long you've had it. But you can take the first step today.

Draw the outline of your hand on paper and color in the parts that tingle. Along with a three-line note: since when, whether it changes when you move your neck, and whether there's any weakness.

Bring that map with you, and we'll check together whether the problem is the bulb or the cord.
