Upper back pain from desk work: why it aches and what helps

Upper back pain from desk work is usually an ache, burn or tight knot between the shoulder blades that builds through the day. It most often comes from long hours in a rounded position, with your head forward, shoulders rolled in and arms reaching for the keyboard or mouse. Raising the screen, bringing the mouse and keyboard close, and breaking up long sittings with a few gentle stretches usually help.

The rest of this post explains why that spot takes the strain, which desk changes make the biggest difference, five stretches you can do in a chair, and how to tell the everyday muscular ache apart from pain that needs a doctor. Pain between the shoulder blades occasionally has nothing to do with your desk, so the last section matters.

Why does my upper back hurt from sitting at a desk?

The muscles between and around your shoulder blades help hold your arms and head in place. At a desk they rarely get a rest. A few common habits make their job harder.

• A rounded upper back. As the day goes on, most people curl forward: chest closes, shoulders roll in, upper back rounds. The muscles between the shoulder blades spend hours holding that shape, and they let you know about it.
• A screen that is too low. This is the big one for laptop users. Looking down at a MacBook on a desk pulls your head forward and down, and your upper back rounds to follow it.
• Reaching for the mouse. A mouse or trackpad parked out to the side, or far forward, keeps one arm stretched out. That shoulder blade gets pulled forward all day, which is why the ache is often worse on one side.
• A keyboard or armrests that are too high. Your shoulders lift to reach, and the muscles across the top of the back and shoulders stay tense.
• Phone calls in the wrong position. A phone held between ear and shoulder, or a long call hunched over the laptop, loads the same area.
• Sitting still. Muscles cope with changing loads much better than with one load held for hours.

The evidence on posture and pain is mixed. Plenty of people round their backs without any trouble, and things like stress, sleep and general activity seem to matter too. So treat these as things to change, not as proof you are sitting "wrong".

Change the setup first

Small changes to the desk often take more strain off than any stretch.

1. Raise the screen. Bring its top edge up to roughly eye level, an arm's length from you, so your head can stay over your shoulders. With a MacBook, that means lifting the laptop and typing on a separate keyboard. Good posture with a MacBook goes through the options.
2. Bring the mouse in. Keep it next to the keyboard and level with it, near enough that your elbow stays tucked in. A keyboard without a number pad leaves less distance to cover.
3. Lower the keyboard. It belongs at about elbow height, with your shoulders relaxed. If the desk is too high for that, raise the chair and put a footrest under your feet.
4. Let the chair hold you. Sit all the way back so the backrest supports you, and lower armrests that push your shoulders up.
5. Use a headset or speakers for calls, so your head stays level and your hands are free.
6. Make text bigger rather than leaning in to read it.

Stretches for between the shoulder blades

These can be done sitting at the desk in a minute or two. Move slowly, keep each one mild, and breathe normally. Stop if anything hurts sharply, makes you dizzy, or causes tingling or numbness in your arms or hands.

Shoulder blade squeeze

Sit tall. Gently draw your shoulder blades back and slightly down, as if tucking them into your back pockets. Hold for a few seconds, then relax. Repeat five to ten times. Don't let your shoulders rise toward your ears.

Chest opener

Clasp your hands behind your back, or hold the back of the chair, and gently lift your chest while your shoulder blades move together. Hold for a few breaths. A tight chest helps pull the shoulders forward, so opening it takes some of the load off the back.

The self-hug

Wrap your arms around yourself as if hugging, hands reaching toward your shoulder blades. Let your upper back round, drop your chin slightly and breathe slowly into the space between your shoulder blades. Hold for a few breaths. It stretches the very muscles that ache.

Upper back extension over the chair

If your chair has a firm backrest that stops around the middle of your back, sit tall, put your hands lightly behind your head with elbows wide, and lean back gently over the top of the backrest. Look up a little, then come back. Skip it on a chair that tips or rolls.

Seated twist

Sit tall with your feet flat. Place your right hand on your left knee and gently turn your chest to the left, looking over your left shoulder. Hold for a few breaths, then come back and do the other side. Turn from the middle of your back, not just your neck.

Two-minute desk stretches has ready-made sets that include the neck and shoulders as well.

Can stress cause pain between the shoulder blades?

It can play a part. Many people tense their shoulders and upper back when they are under pressure, and breathe shallowly into the chest. Hold that through a stressful week and the area can end up sore and tight, often worse on the days the inbox is worst. How much stress itself causes pain is not fully understood, but the link between tension and that familiar knot is something most desk workers recognize.

What helps is noticing. A few times a day, check whether your shoulders have crept up, let them drop, unclench your jaw, and take a couple of slow breaths into your belly rather than your chest. Why your shoulders creep up at the desk has more on this.

A patient bonsai for a tense back

You can't notice tension while you are deep in work, which is where Notchpals helps. Its characters take turns at your Mac's notch, one for each area of your day, and the Posture one keeps watch on exactly this. If that is Matsu, a bonsai with three centuries of patience, you get a few visits a day. Some are posture checks. Others are a Shoulders down, aimed squarely at the knot between your shoulder blades:

MatsuLet your shoulders fall, like branches when the snow slides off.

Once each afternoon or early evening, Matsu also asks you to check the distance to your screen, a good moment to notice whether your head has crept forward again. Add a Movement character and you get stretch reminders too, plus a nudge to stand once you have been sitting for most of an hour. The repeating visits share one gentle daily allowance, so they arrive as an occasional tap on the shoulder, never a stream.

When to get it checked

An everyday muscular ache that eases when you move, stretch or change your setup is common. See a doctor or physiotherapist if:

• it is still there after a few weeks, or keeps coming back despite the changes above,
• you have numbness, tingling or weakness in your arms or hands,
• it wakes you at night or is there all the time, whatever position you are in,
• it follows a fall or injury, or comes with a fever, feeling unwell, or weight loss you can't explain.

Pain between the shoulder blades can sometimes come from the heart, lungs or other organs rather than muscles. Call emergency services straight away if upper back pain comes with chest pain or pressure, shortness of breath, sweating, nausea, or pain spreading into your arm, neck or jaw, or if it starts suddenly and is severe.

If you do see a physiotherapist, ask someone to take a side-on photo of you at your desk in the middle of the afternoon, or prop your phone up and use the timer. It can tell them a lot about your setup that is hard to describe.
