That dull, persistent ache between your shoulder blades. You know the one. It builds through the day, gets worse after hours at a desk, and no amount of rolling your shoulders or stretching your neck seems to shift it for long. You try to ignore it. You roll it out on a foam roller, crack your back against the chair, and tell yourself it’ll pass.
Sometimes it does. But for a lot of Aucklanders, it keeps coming back – a little worse each time, a little harder to shake.
Interscapular pain – the clinical term for pain between the shoulder blades – is one of the most common complaints we see at Physio Connect. It’s also one of the most misunderstood, because the pain you feel in that region often isn’t coming from there at all.
Here’s what’s actually going on, and – more importantly – what you can do about it.
Why Does It Hurt Between My Shoulder Blades?
The thoracic spine – the middle section of your back, running from the base of your neck to just above your lower back – is built for stability rather than mobility. It’s surrounded by the ribcage and supported by multiple layers of muscle. That stability is what lets you breathe, twist, and carry load without your spine buckling.
But that same stability means that when things go wrong in this region, they tend to stay wrong. The thoracic spine doesn’t have the same capacity for self-correction as the neck or lower back. Without targeted treatment, problems here tend to become chronic – not dangerous, but persistently uncomfortable in a way that quietly erodes your quality of life.
These are the most common reasons we see people presenting with interscapular pain:
1. Muscle Tension and Postural Overload
This is the most common cause by a significant margin, and it’s almost entirely a product of how we spend our days.
Hours at a laptop, looking down at a phone, driving with rounded shoulders, sitting in a chair that doesn’t support your upper back – all of these put the rhomboid muscles (which run from your spine to your shoulder blades) under constant, low-level strain. Over time, they fatigue, tighten, and start referring a dull, burning ache across the upper back.
The insidious thing about postural tension is that it develops so gradually you don’t notice it building. By the time it’s painful enough to address, the pattern is already well established.
What it feels like: A heavy, tight ache that builds through the day and eases somewhat with rest. Worse after long periods of sitting or screen time. Temporarily relieved by stretching, but it keeps coming back within hours.
2. Thoracic Joint Stiffness
The joints between the vertebrae in your thoracic spine can become stiff and irritated – particularly in people who sit for long periods or have spent years in a forward-flexed posture. When these joints stop moving freely, the surrounding muscles work harder to compensate. The result is a cycle of stiffness, muscle tension, and aching that’s difficult to break without manual therapy.
Thoracic stiffness is also one of the most satisfying things to treat. The right hands-on mobilisation can restore movement that’s been restricted for years – and patients often notice an immediate difference in how freely they can breathe and rotate.
What it feels like: Stiffness when rotating or extending the upper back. That familiar urge to “crack” your back for relief – but the relief is short-lived. Morning stiffness that eases with movement but returns with prolonged sitting.
3. Neck Referral
This is the one that catches people off guard most often.
The nerves that exit the lower cervical spine supply sensation to the upper back and shoulder blade region. When these nerves are irritated – through a stiff joint, a disc issue, or chronic muscle tension in the neck – the pain shows up between the shoulder blades, not in the neck itself. The neck can feel completely fine while the upper back aches constantly.
This is why treating the shoulder blades directly sometimes doesn’t work. If the source is the neck, that’s where the treatment needs to go.
What it feels like: An ache between the blades that doesn’t change much with shoulder movement. May come with neck stiffness, headaches, or occasional pins and needles into the arm. Often worse after sleeping in an awkward position.
4. Trigger Points in the Rhomboids and Trapezius
Trigger points are tight, hypersensitive spots within a muscle that refer pain to nearby areas. The rhomboids, upper trapezius, and levator scapula are prime locations for trigger points that produce interscapular pain – and they’re notoriously stubborn without hands-on treatment.
If you’ve ever had someone press on a spot between your shoulder blades and felt that distinctive combination of “ouch” and “please don’t stop,” you’ve found a trigger point.
What it feels like: A specific, reproducible ache you can almost point to with one finger. Pressing on it is painful but also strangely satisfying. Common in people who do a lot of keyboard and mouse work, or who carry tension in their upper back.
5. Rib Joint Irritation
Each rib attaches to the thoracic spine at a small joint called the costovertebral joint. These joints can become inflamed or restricted – particularly after a prolonged coughing illness (which we’ve seen a lot of in recent years), a sudden twisting movement, or extended periods of poor posture.
The pain from an irritated rib joint can be surprisingly sharp and catching, or it can present as a persistent dull ache that mimics muscular tension. It often gets misdiagnosed as a muscle problem and treated accordingly – without much success.
What it feels like: Pain that worsens with deep breathing, twisting, or certain arm positions. Can feel like it wraps around to the front of the chest. Often worse when lying on the affected side at night.
6. When to Rule Out Something More Serious
In the vast majority of cases, pain between the shoulder blades is musculoskeletal – meaning it comes from the muscles, joints, and nerves of the spine and shoulder region. It’s uncomfortable, but it’s not dangerous.
However, in rare cases, interscapular pain can be referred from internal structures including the heart, lungs, oesophagus, or gallbladder. This is uncommon, but it’s worth knowing the signs that warrant urgent medical attention rather than a physio appointment.
Go to A&E or call your GP urgently if:
- The pain came on suddenly and severely with no obvious physical cause
- You have chest tightness, shortness of breath, or pain radiating down your left arm (call 111)
- You have unexplained weight loss, fever, or night sweats alongside the back pain
- The pain is constant, doesn’t change with movement, and is getting progressively worse
If none of those apply – and for most people reading this, they won’t – you’re almost certainly dealing with a musculoskeletal issue that a physio can help with.
When to See a Physio
Upper back pain between the shoulder blades is very treatable – but it responds best to hands-on physiotherapy, not just stretching and hoping.
Book in with a physio if:
- Pain has been present for more than 72 hours
- It’s affecting your sleep or your ability to concentrate at work
- Home exercises aren’t making a lasting difference
- You have pins and needles, numbness, or weakness in your arm
- The pain came on after a fall, accident, or sudden movement
- You’ve had this before and it keeps coming back
What to expect from your first appointment at Physio Connect:
We’ll start with a thorough assessment to work out exactly where the pain is coming from – whether that’s the thoracic spine, the neck, the ribs, or the shoulder itself. From there, we’ll use hands-on manual therapy to restore movement and release tension, and give you a targeted home exercise programme that addresses the specific cause of your pain.
We can also refer for imaging – ultrasound or X-ray – if needed, without requiring a GP visit first.
Most people with interscapular pain notice a significant improvement within 3-6 sessions. Some see improvement after the very first appointment.
Upper back pain between the shoulder blades rarely sorts itself out without the right treatment. If yours has been hanging around for more than a week, it’s time to get it properly assessed.
Our Auckland physios will find the source of the problem, get you moving freely again, and make sure it doesn’t keep coming back.
No GP referral needed. Book online or call 0800 111 788.
Frequently Asked Questions
Is My Upper Back Pain Covered by ACC
If your pain started as the result of an accident, a workplace incident, or a sudden movement injury, ACC may cover your treatment costs. You don’t need a GP referral to access ACC-funded physiotherapy – you can book directly with Physio Connect and we’ll handle the claim process on your behalf.

Why do I have pain between my shoulder blades?
The most common causes are postural muscle tension, thoracic joint stiffness, trigger points in the rhomboids or trapezius, and referred pain from the neck. A physiotherapy assessment is the most reliable way to identify which is driving your pain.
Can a physio help with upper back pain between the shoulder blades?
Yes – this is one of the most common and most treatable presentations we see. Hands-on manual therapy combined with targeted exercises and postural correction typically produces significant improvement within a few weeks.
How long does interscapular pain take to resolve?
Most people see meaningful improvement within 3-6 physiotherapy sessions. Chronic cases that have been present for months or years may take longer, but most patients notice a difference after their first appointment.
Can neck problems cause pain between the shoulder blades?
Yes, and this is more common than most people realise. The nerves exiting the lower cervical spine supply the upper back and shoulder blade region. Irritation in the neck can refer pain directly between the blades, even when the neck itself feels fine.
What exercises help shoulder blade pain?
Thoracic extension over a rolled towel, shoulder blade squeezes, thread the needle, chin tucks, and doorway chest stretches are all evidence-supported exercises for interscapular pain. Your physio will tailor a programme to your specific cause.
