Upper back pain between your shoulder blades from sitting

Why sitting puts the ache right there

The spot between your shoulder blades belongs to your upper (thoracic) spine and a handful of muscles: the rhomboids, which connect the inner edge of each shoulder blade to your spine, and the middle part of the trapezius layered over them. Their main job is to pull your shoulder blades back and hold them steady.

Now picture a normal workday. Screen a little low, keyboard a little far, your chest drifting toward both. Your shoulders roll forward, your upper back rounds, and your head slides ahead of your body. The muscles between your shoulder blades end up holding a heavy, forward load in a lengthened position for hours. They aren’t short. They’re tired, like holding a full shopping bag with your arm half extended.

A physiatrist at Hospital for Special Surgery calls posture probably the biggest contributing factor to pain in this area, and explains that sitting rounded for hours a day, week after week, can create muscle imbalances. Weak upper back muscles get overpowered and let the shoulder blades drift out of position. Cleveland Clinic likewise lists poor posture and muscle strain among the common causes of upper back pain.

Two other desk habits feed it. Stress makes you hold your shoulders up and tense without noticing, and your neck can refer pain down into this spot, so a stiff neck and a sore upper back often turn up together. Your chest, meanwhile, spends the day shortened, which is why the fix starts at the front of your body, not only the back.

Which kind of pain is it?

Not every ache between the shoulder blades has the same cause. This rough guide helps you pick a starting point. It isn’t a diagnosis, and anything in the last row skips the stretches entirely.

Six moves for pain between the shoulder blades

This routine follows a simple rule: mobilize the upper back, stretch the front, strengthen the back. Moves 1–3 bring quick relief. Moves 4–6 are the ones that stop the ache returning, because they give the tired muscles between your shoulder blades the strength to hold you up. All six work in a desk chair or next to it. Move slowly, stay in mild tension, and stop if anything is sharp, causes tingling, or makes the pain spread.

1. Seated thoracic extension

1. Setup: sit in a sturdy chair whose backrest reaches about the bottom of your shoulder blades. Cross your arms over your chest or lightly support your head with your hands.
2. Move: lean back and gently arch your upper back over the top of the backrest, lifting your chest toward the ceiling.
3. Hold: 3–5 seconds, then sit up. Repeat 5–8 times.
4. Don’t: use a rolling or reclining chair, let your head drop back, or arch from your lower back instead.

This is the direct opposite of the desk slump, and it often feels like the first full breath of the afternoon.

2. Seated thoracic rotation

1. Setup: sit tall toward the front of your chair, feet flat and hip-width apart, arms crossed over your chest with hands on opposite shoulders.
2. Move: keeping your hips and knees facing forward, rotate your upper body to the right as far as is comfortable. Return to center, then rotate left.
3. Hold: 2–3 seconds at the end of each turn. Do 8 turns per side.
4. Don’t: yank yourself around with the armrest or let your knees swing with you. The twist comes from the middle of your back.

3. Upper back stretch (the “hug a beach ball”)

1. Setup: sit or stand tall and reach both arms forward at shoulder height, hands clasped or crossed.
2. Move: push your hands away from you and let your upper back round, spreading your shoulder blades apart. Drop your chin slightly.
3. Hold: 20–30 seconds, breathing into your back. Repeat 2–3 times.
4. Don’t: shrug toward your ears or hold your breath.

This is the stretch that feels best on a sore spot, and it’s fine to use for relief. Just remember it stretches muscles that are often already long. It’s the painkiller, not the cure. Variation: cross your arms at the elbows and lift them (eagle arms) for a deeper pull between the shoulder blades.

4. Doorway chest stretch

1. Setup: stand in a doorway with one foot forward and your forearms on the frame, elbows at about shoulder height.
2. Move: lean gently forward through the front foot until you feel a stretch across your chest and the front of your shoulders.
3. Hold: 20–30 seconds, 2–3 times.
4. Don’t: arch your lower back or let your head poke forward through the door.

A tight chest pulls your shoulders forward, and every inch it pulls is an inch the muscles between your shoulder blades have to pull back. No doorway handy? Clasp your hands behind your lower back and lift your chest for 20 seconds.

5. Shoulder blade squeeze

1. Setup: sit tall, arms by your sides with elbows bent to 90 degrees.
2. Move: draw your shoulder blades back and down, as if tucking them into your back pockets, letting your elbows travel back with them.
3. Hold: 5 seconds, then release. Repeat 10 times.
4. Don’t: shrug or push your ribs forward. The movement is small and comes from the shoulder blades.

6. Band pull-apart (or towel pull)

1. Setup: stand or sit tall holding a light resistance band at shoulder width, arms straight in front of you at chest height. No band? Hold a towel taut between your hands.
2. Move: squeeze your shoulder blades together as you pull the band apart, bringing your hands out toward your sides. With a towel, pull outward hard against it without letting it move.
3. Reps: 10–15 slow pull-aparts, or 3 towel pulls of about 10 seconds each.
4. Don’t: lean back, shrug, or snap the band back. Control both directions.

This is the move most desk workers skip and most need. A 2017 systematic review in the South African Journal of Physiotherapy looked at exercise for office workers with neck pain and found the clearest benefit for strengthening exercises. That review is about the neck, not specifically the spot between your shoulder blades, but the muscles overlap and HSS’s advice for this area points the same way: strengthen pulling movements such as rows and reverse flys. Keep a band in your desk drawer. It costs less than lunch.

Fix the desk, or you’ll stretch forever

The stretches undo some of the day. Your setup decides how much there is to undo. Most of these changes take five minutes and cost nothing.

• Raise the screen. The top of your monitor should be at or slightly below eye level, about an arm’s length away. A laptop on a stand, with a separate keyboard and mouse, stops your whole upper body folding down toward it.
• Bring the keyboard and mouse close. Reaching forward for them pulls your shoulder blades apart all day. Elbows should rest near your sides, bent at roughly 90 degrees.
• Sit back. Use the backrest. Perching on the front edge and leaning in hands the whole job to the muscles between your shoulder blades.
• Drop your shoulders. If your armrests or desk are high enough to push your shoulders up, lower them. Check a few times a day whether your shoulders have crept toward your ears. They usually have.
• Zoom in. Leaning toward the screen to read is a sign the text is too small. Increase it before your nose meets the monitor.

Even a perfect setup won’t save you from sitting still. An NHS physiotherapy leaflet on thoracic back pain links long-held poor posture to pain between the shoulder blades and recommends changing position every 20–30 minutes. For why short, frequent breaks beat one long one, see how long is too long to sit.

A workday schedule for your upper back

You don’t need a gym session. You need small doses that interrupt the slump before it settles in. One way to spread the six moves across a day:

That’s about ten minutes in total, spread out so no single block feels like a commitment. If you want the reasoning behind the break rhythm, read how often you should stretch at work. If your neck is part of the story, the neck and shoulder pain guide covers the upper traps and the side of the neck.

Common mistakes

• Only stretching the sore spot. It feels great for ten minutes. Then you sit back down in the same slump and the muscles go straight back to work.
• Forcing “perfect posture” all day. Bracing your shoulders back for eight hours just swaps one held position for another. No single posture is good for hours. Move often instead.
• Skipping the strength work. The pull-aparts and squeezes are boring. They’re also the part that lasts.
• Relying on a posture brace. A brace can remind you where your shoulders belong, but it holds you in place instead of building the muscles that should do it. Use it as a reminder, not a replacement.
• Ignoring the phone. Fixing your monitor and then spending your evening hunched over a phone gives the same muscles the same job.
• Waiting until it hurts. Fatigue builds over hours. A 30-second break at 10 am beats a 10-minute rescue at 5 pm.

Make it a habit, not a rescue

The moves are easy. Remembering them is the hard part, because the slump happens exactly when you’re absorbed in something and not thinking about your back at all. “I’ll sit up straighter” lasts until the next interesting email.

Attach the moves to things that already happen: shoulder blade squeezes when a meeting ends, a doorway stretch on the way to the kitchen, rotations while a build or upload runs. Then cover the long focus blocks with reminders. Stiff’s reminders fire only during the work hours you set, its stretch library covers the back and shoulders, and the Back Reset and Neck & Shoulder Reset programs bundle them into a few guided minutes. A daily XP goal and a streak make skipping slightly more annoying than doing it, which is the whole trick. More habit ideas are in how to remember to stretch at work, and the full set of office-friendly moves is on the desk stretches page.

When to see a doctor

Most desk-related pain between the shoulder blades is muscular and improves with movement, a better setup, and time. Some causes are not muscular at all, and this spot is one where it pays to know the difference.

Call emergency services right away if the pain comes with chest pain or pressure, shortness of breath, nausea, a cold sweat, lightheadedness, or pain spreading to your arm, neck, or jaw. Mayo Clinic lists pain that spreads to the back among heart attack symptoms, and its cardiologists note that in women the pain can sit between the shoulder blades. Cleveland Clinic also flags sudden, tearing chest and back pain, which can signal a tear in the aorta. Don’t stretch through any of these.

See a doctor or physical therapist soon if:

• The pain lasts more than a week or keeps getting worse despite breaks and stretching.
• It started after a fall, accident, or other injury.
• You have numbness, tingling, or weakness in your arms or legs.
• It comes with fever, unexplained weight loss, or night pain that doesn’t ease when you change position.
• It hurts more when you breathe deeply.

And if any move in this guide causes sharp pain or pins and needles, stop doing it. A physical therapist can tell you which exercises suit your back and which to leave out.
