Why Does My Back Hurt Between My Shoulder Blades?

Pain between your shoulder blades is almost always caused by muscle strain or poor posture, particularly in the rhomboid muscles that connect your shoulder blades to your spine. It’s one of the most common upper back complaints, and in most cases it responds well to simple changes in how you sit, move, and strengthen your back. Less commonly, the pain can originate from a pinched nerve in the neck, a digestive issue, or, rarely, a vascular emergency.

The Muscles Most Often Responsible

The rhomboid muscles run from the inner edges of each shoulder blade to your spine. Their job is to pull your shoulder blades together and stabilize them during arm movements. When these muscles are overworked, strained, or locked in spasm, you feel a dull ache or burning sensation right in the middle of your upper back.

Common triggers include overhead activities like serving a tennis ball or placing items on high shelves, rowing motions, and carrying a heavy backpack (especially on one shoulder). But the most frequent culprit is far less dramatic: sitting hunched over a computer for hours. That sustained posture keeps the rhomboids stretched and under constant low-level tension, which eventually produces pain.

The trapezius muscle, which covers a broad diamond shape from your skull down to the middle of your back, can also refer pain to this area. When the middle fibers of the trapezius develop trigger points, tight knots that form from repetitive strain, they create a deep ache between the shoulder blades that can persist for days.

How Posture Creates a Cycle of Pain

If your pain shows up during or after long stretches of desk work, there’s a recognized pattern behind it. A postural imbalance called upper crossed syndrome develops when the chest muscles and the muscles at the top of your shoulders become chronically tight, while the muscles in the mid-back and the deep stabilizers along the front of your neck grow weak. The result is a rounded upper back, forward-jutting head, and shoulder blades that wing outward instead of sitting flat.

This imbalance puts the rhomboids and lower trapezius in a permanently lengthened, weakened position. They’re being asked to stabilize your shoulder blades against the pull of much stronger chest muscles, and they lose that tug-of-war. The pain you feel is those mid-back muscles protesting under constant strain.

Phone use compounds the problem. When you tilt your head forward to look at a screen, the effective load on your neck and upper back increases dramatically. At just 15 degrees of forward tilt, the force on your cervical spine jumps to about 27 pounds. At 45 degrees, a common texting angle, it reaches roughly 49 pounds. At 60 degrees, it hits 60 pounds. Your upper back muscles have to absorb all of that extra load, and over months or years, the strain accumulates.

When the Problem Is Actually in Your Neck

This surprises many people: a pinched nerve in the neck is one of the most common sources of pain felt between the shoulder blades. Cervical radicular pain, caused by a herniated disc or bone spur compressing a nerve root, most frequently radiates to the interscapular region rather than down the arm. The C7 nerve root, located in the lower neck, accounts for about 70% of cervical nerve compression cases, followed by C6 at roughly 19 to 25%.

If your interscapular pain comes with numbness, tingling, or weakness that travels into one arm or hand, or if it gets worse when you look up or tilt your head to one side, a cervical nerve issue is worth investigating. The pain pattern can mimic a simple muscle strain, so it’s often missed on the first pass.

Non-Muscular Causes Worth Knowing

Gallbladder inflammation can refer pain to the right shoulder blade area, particularly after fatty meals. This pain tends to come in waves and may be accompanied by nausea. Acid reflux and peptic ulcers can also produce a burning sensation in the upper back, though they usually come with more obvious digestive symptoms.

Aortic dissection, a tear in the wall of the body’s largest artery, is rare but worth recognizing because it is life-threatening. The hallmark is a sudden, severe tearing or ripping pain in the chest or upper back that starts abruptly, not gradually. It may be accompanied by shortness of breath, fainting, a rapid weak pulse, heavy sweating, confusion, or vision changes. This is a 911 situation, not something that builds over days or weeks.

Red Flags That Need Prompt Attention

Most interscapular pain is benign, but certain combinations of symptoms warrant urgent evaluation:

  • Sudden, severe tearing pain with dizziness, fainting, or vision changes (possible vascular emergency)
  • Weakness, balance problems, or changes in bowel or bladder control (possible spinal cord compression)
  • Fever, night sweats, or unexplained weight loss alongside back pain (possible infection or malignancy)
  • Pain that doesn’t let up at rest, wakes you from sleep consistently, or worsens over weeks despite conservative care
  • Numbness or tingling in both hands or legs, or a sensation like an electric shock running down your spine when you bend your neck forward

Fixing Your Workstation

If your pain tracks with desk time, adjusting your setup can make a measurable difference. Place your monitor about an arm’s length away, no closer than 20 inches and no further than 40 inches. The top of the screen should sit at or slightly below eye level so you’re not tilting your head down. If you wear bifocals, lower the monitor an additional 1 to 2 inches for comfortable viewing.

Set your chair height so your feet rest flat on the floor with your thighs parallel to it. Position armrests so your elbows stay close to your body and your shoulders can relax rather than hike up. Keep your wrists straight and your hands at or slightly below elbow level when typing. These adjustments reduce the forward-head posture that overloads your mid-back muscles.

Exercises That Target the Right Muscles

Corrective exercises work by strengthening the weak mid-back muscles and restoring balance with the tighter chest and upper shoulder muscles. Consistency matters more than intensity here. A few minutes spread throughout the day is more effective than one long session.

Scapular Retractions

Gently squeeze your shoulder blades together without shrugging your shoulders up. Hold for 3 to 5 seconds, then release. Aim for 10 to 15 repetitions, three to four times per day. This directly targets the rhomboids. Once this feels easy, add a resistance band to increase the challenge, doing 2 sets of 12 to 15 repetitions.

Wall Slides

Stand with your forearms flat against a wall, then slide them upward while pressing through your shoulder blades. This targets the serratus anterior, a muscle along the side of your rib cage that helps anchor the shoulder blade flat against your back. Do 10 to 15 repetitions for 2 sets.

Dynamic Hug

Loop a resistance band around your back and hold the ends in each hand. Push your arms forward in a hugging motion, focusing on spreading your shoulder blades apart. This also trains the serratus anterior. Do 2 to 3 sets of 10 to 15 repetitions.

Push-Up Plus

Perform a standard push-up, but at the top of the movement, push further so your upper back rounds slightly and your shoulder blades spread apart. That extra push at the top is what activates the stabilizing muscles. Start with 2 sets of 8 to 10 repetitions. If a full push-up is too demanding, do these from your knees or against a wall.

Most people with posture-related interscapular pain notice improvement within two to four weeks of consistent exercise and workstation adjustments. If the pain hasn’t budged after six weeks of daily effort, or if it’s getting worse, that’s a reasonable point to seek a hands-on evaluation to rule out a cervical disc issue or another structural cause.
