Upper Back Pain Between the Shoulder Blades: Causes and Relief

Written and reviewed by Dr. Nathan Beyerl, DC, Doctor of Chiropractic, The Bridge Chiropractic, Carlsbad.

Most people describe pain between the shoulder blades as a knot that never quite releases. You dig at it with a lacrosse ball, you get twenty minutes of relief, and by the afternoon it is back exactly where it was.

The reason it keeps coming back is usually that the muscle is not the actual problem. It is the part that hurts, which is not the same thing. A rhomboid that stays tight for months is often working overtime to compensate for something else that is not moving, and until that something else changes, the muscle has a reason to keep gripping.

Here is what is actually going on between your shoulder blades, how to tell the three main causes apart, and the short list of symptoms that mean this needs a medical assessment rather than a mobility routine.

The common causes at a glance

Muscle, joint, or rib?

These three feel different, and telling them apart matters because they respond to different things.

Muscular pain is usually a broad ache you can point to and press on, and pressing on it reproduces the pain you came in with. It tends to build over a day and eases with heat and movement. It is the most common presentation and the least concerning.

Thoracic joint restriction feels stiffer than it feels sore. People describe wanting to crack their upper back and not being able to get there. It is often worse after a night's sleep or a long stretch of sitting, and it improves once you start moving. Rotation is often noticeably easier one way than the other.

Rib involvement is the one patients almost never connect. The ribs join the spine at two small joints each, and those joints move every time you breathe. When one is not moving well, you get a sharp or catching pain that shows up on a deep breath, a cough, a sneeze, or rolling over in bed. If your upper back pain has a breathing component and nothing about it feels like a normal muscle ache, this is often why.

The practical test most people can do at home: does it change with movement and position? Mechanical problems, all three of the above, change with what you do. Pain that stays exactly the same regardless of how you move, sit, or breathe deserves a different kind of look, which is covered further down.

Why massaging the knot does not fix it

A rhomboid between your shoulder blades does not decide to tighten for no reason. It usually tightens because it is doing a job that something else has stopped doing.

The two most common versions of this: a stiff thoracic spine that will not rotate or extend, so the muscles around it brace to create stability the joints are not providing; and a shoulder blade sitting in a poor position, usually pulled forward and rotated down, so the muscles that should be holding it are working at a length where they are weak.

In both cases the knot is a symptom. Release it and you get short term relief, because you have reduced the tension without changing the reason for the tension. Restore the thoracic motion or improve how the shoulder blade sits, and the muscle usually stops needing to grip.

This is why the treatment that works is almost never just soft tissue work. Soft tissue therapy makes the area comfortable enough to move well. The movement is what makes it stay better.

The desk connection

San Diego has a lot of people at screens, and this presentation follows the working day closely.

Four things drive most of it. Sustained position, not bad posture specifically. Any position held long enough becomes the problem, which is why position changes beat perfect ergonomics. Monitor height, because a screen below eye level pulls the head and upper back forward for hours. Laptop use without a separate keyboard, which forces a choice between a good screen height and a good hand position, and you cannot have both on one device. One sided load, meaning a bag on the same shoulder every day, a phone held to the same ear, or a mouse hand that lives further from the body than the other.

The fix is boring and it works: raise the screen, separate the keyboard, alternate the sides you load, and get out of whatever position you are in every half hour or so. Our guide to desk setup covers the workstation side of this in more detail.

What actually helps

A short routine done most days beats a long one done occasionally. This is roughly what we give people to start with.

Two notes. Roll the thoracic spine, not the lower back. And if a deep breath is sharp rather than tight, prioritise the breathing work and get the ribs assessed before pushing into end range rotation.

Targeted soft tissue therapy helps a lot here, particularly early, because it makes the area tolerable enough to do the movement work properly. It is the movement work that changes the outcome.

Referred pain, and when to take it seriously

Almost all pain between the shoulder blades is mechanical. Occasionally it is not, because that area is a known referral site for several organs, and it is worth knowing the difference calmly rather than not knowing it at all.

Get prompt medical assessment, rather than manual therapy, if the pain:

• comes on with exertion and eases with rest
• comes with shortness of breath, sweating, nausea, or light headedness
• does not change at all with movement, position, or breathing
• started suddenly and severely, with no mechanical trigger
• comes with fever, unexplained weight loss, or night pain that wakes you
• follows significant trauma such as a fall or a collision
• comes with chest, jaw, or left arm symptoms

If you have chest pain with shortness of breath, sweating, or nausea, call 911 rather than booking anything.

None of that is common, and the overwhelming majority of upper back pain is a mechanical problem that responds well to treatment. But a good assessment starts by ruling the serious things out rather than assuming, and any practitioner worth seeing will do that before they treat you.

How we approach it at The Bridge

We start with an assessment, because the three mechanical causes above look similar from the outside and respond to different treatment. That means checking thoracic motion segment by segment, checking rib movement with breathing, looking at how the shoulder blade sits and moves, and screening for the non mechanical causes listed above.

From there, treatment is usually a combination: adjustment or mobilisation for the restricted joints, soft tissue therapy for the muscles that have been compensating, and movement and strength work so it stops recurring. That last part is the one that determines whether you are back in three months.

If you are not sure whether what you have is a muscle, a joint, or a rib, that is exactly what a first visit is for.

Frequently Asked Questions

What causes pain between the shoulder blades?

Most commonly a muscular strain or trigger point, a stiff thoracic joint, a rib joint that is not moving well, or a shoulder blade sitting in a position that makes the surrounding muscles work too hard. Desk work, one sided carrying, and a new lifting load are the usual triggers. Less commonly, pain in this area can refer from an organ, which is why pain that does not change with movement or position should be assessed medically.

Why does it hurt between my shoulder blades when I breathe?

That pattern points to the rib joints. Each rib meets the spine at two small joints that move with every breath, so when one is restricted or irritated you get a sharp or catching pain on a deep breath, a cough, or a sneeze. It is a common and treatable mechanical problem, but pain on breathing that comes with shortness of breath, fever, or chest symptoms needs medical assessment first.

How do I get rid of a knot between my shoulder blades?

Pressure on the knot gives short term relief but rarely lasts, because the muscle is usually tight for a reason. The combination that works is restoring thoracic mobility, improving how the shoulder blade sits and moves, strengthening the muscles that hold it, and using soft tissue work to make the area comfortable enough to do that. If it keeps returning after months of rolling and stretching, the cause is somewhere other than the spot that hurts.

When is upper back pain serious?

When it does not behave mechanically. Pain that comes with exertion, shortness of breath, sweating or nausea, pain unrelated to movement or position, sudden severe onset without a trigger, pain with fever or unexplained weight loss, night pain that wakes you, or pain following significant trauma all warrant prompt medical assessment. Chest pain with shortness of breath, sweating, or nausea is a 911 call.

Get it assessed properly

If the knot between your shoulder blades keeps coming back, the useful next step is finding out what it is compensating for. Start with a free discovery call, 20 to 30 minutes on the phone with Dr. Beyerl. That is enough to work out whether you are dealing with a muscle, a joint, or a rib, and what would actually change it.
