What Causes Upper Back Pain Between Shoulder Blades?

There is something particularly aggravating about pain between your shoulder blades. It sits in that awkward zone your hands can barely reach, it flares every time you move your arms, and it tends to hang around long after you expect it to fade.

This part of your back, technically called the thoracic region, is home to a complex system of muscles, joints, nerves, and structures. Pain here can come from many different sources, and identifying the right one is the key to getting effective relief.

Muscle Strain And Overuse

The most common cause of pain in this region is simple but impactful: overworked or strained muscles. The rhomboids, trapezius, and erector spinae muscles run through the upper back and are involved in nearly every arm and shoulder movement you make.

When you sit at a desk for extended periods, perform repetitive overhead movements, or lift improperly, these muscles develop micro-tears and inflammation that manifests as chronic back pain between the shoulder blades.

Scapulothoracic Bursitis

One frequently overlooked answer to what causes upper back pain between the shoulder blades is a condition called scapulothoracic bursitis. There is a bursa located between your shoulder blade and the rib cage underneath it, and when that bursa becomes inflamed, every movement of your arm or shoulder blade can produce pain and friction.

People who do a lot of rowing, lifting, or overhead work are particularly susceptible. A characteristic grinding or snapping sensation, sometimes called scapular snapping, often accompanies this condition.

Spinal And Disc-Related Causes

The thoracic spine itself can be the origin of pain between the shoulder blades. Degenerative disc disease, thoracic facet joint arthritis, and vertebral compression fractures can all refer pain into this region. Unlike muscle pain, spinal causes often produce a sharper, more localized discomfort that worsens with specific movements or positions.

Cervical disc problems can also refer to pain downward into this area. If you have neck issues alongside your upper back pain, the two may well be connected.

Postural And Mechanical Contributors

Mechanical back pain is another important answer to what causes upper back pain between the shoulder blades. When your core muscles are weak and your shoulders roll forward, the muscles in your upper back are forced to work overtime just to keep you upright.

This is one of the most modifiable causes. Targeted strengthening exercises, posture correction, and breaking up sedentary behavior go a long way toward resolving this type of pain.

When To See A Doctor

While most upper back pain between the shoulder blades has musculoskeletal origins, some cases require medical evaluation. See a doctor if you have pain accompanied by fever, unexplained weight loss, numbness or tingling in your arms, or pain that worsens at night or does not improve with rest.
