Upper back pain is one of the most common physical complaints among adults. Nearly 39% of U.S. adults report back pain in any given three-month period, making it the single most common pain site in the body. Your upper back, also called the thoracic spine, runs from the base of your neck to the bottom of your ribcage. Pain in this region usually comes from strained muscles or stiff joints, but it can also signal something happening deeper in the body. Here’s how to sort through the possibilities.
The Most Common Causes
The vast majority of upper back pain comes from soft tissue problems: muscles that are overworked, ligaments that are overstretched, or joints that have stiffened from sitting in the same position too long. Specifically, your upper back can hurt because of:
- Muscle strain or imbalance. The trapezius, a large diamond-shaped muscle spanning your neck, shoulders, and mid-back, is the most frequent culprit. When it’s irritated, you can feel pain between your shoulder blades, up into your neck, or even as a headache. Smaller muscles underneath, like the rhomboids, can produce a deep ache right along the inner edge of the shoulder blade.
- Ligament sprains. Sudden movements, awkward sleeping positions, or lifting something heavy with poor form can stretch the ligaments connecting your vertebrae.
- Joint stiffness. The joints where your ribs connect to your spine can stiffen and become painful, especially if you spend hours hunched over a desk or phone.
- Gradual wear and tear. Repetitive stress on the tissues of the thoracic spine builds up over weeks and months, often without a single obvious injury.
These mechanical causes share a pattern: the pain usually gets worse with certain movements or positions and improves with rest or a change in posture. If your pain fits that description, it’s very likely musculoskeletal.
When the Problem Is a Disc or Nerve
Herniated discs in the upper back are rare compared to the lower back, which is partly why they’re often missed or mistaken for something else. When a thoracic disc does herniate and press on nearby structures, the symptoms tend to be distinct. About 52% of people with a symptomatic thoracic disc herniation experience radiculopathy, which feels like a band of burning, shooting, or electrical pain that wraps around one side of the ribcage following the path of a nerve. About 70% develop myelopathy, where the spinal cord itself is compressed, leading to heaviness or clumsiness in the legs, difficulty with balance, or changes in bladder or bowel control.
If your upper back pain stays between your shoulder blades and feels muscular, a disc problem is unlikely. If pain radiates around your ribs or you notice any changes in coordination or leg strength, an MRI is the most accurate tool for seeing what’s happening with the discs and spinal cord.
Pain That Comes From Somewhere Else
Your upper back can hurt even when the spine itself is fine. Several internal organs refer pain to this area, and it’s worth knowing what those patterns look like because they require very different responses than a muscle strain.
A spasm in the esophagus can produce a twisting pain right between your shoulder blades, sometimes mistaken for a back injury. Angina, reduced blood flow to the heart, can show up as upper back pain rather than chest pain, especially in women. A sudden, sharp pain between the shoulder blades can signal a ruptured spleen, which is a medical emergency. Lung conditions like pleurisy cause back pain that worsens when you take a deep breath. And while kidney pain usually hits lower, it can sometimes reach the bottom of the upper back.
The key difference is context. Referred organ pain typically doesn’t change with movement or position the way muscular pain does. It may come with other symptoms like shortness of breath, nausea, fever, or pain that worsens after eating. If your upper back pain appeared suddenly, doesn’t behave like a muscle problem, or comes with any of these additional symptoms, the cause may not be in your back at all.
Red Flags Worth Taking Seriously
Most upper back pain is harmless and temporary. But the thoracic spine is one area where clinicians stay alert for serious underlying causes, because pain here can occasionally be the first sign of spinal infection, a tumor, or a significant disc problem. Pain that wakes you up at night or gets worse when you’re resting (not moving, not loading the spine) is considered a red flag on its own. Unexplained weight loss, fever, a history of cancer, or pain that started after a significant fall or accident all warrant prompt evaluation. These scenarios are uncommon, but they’re the reason thoracic pain gets a closer look than, say, a sore shoulder.
How Your Desk Setup Contributes
If you work at a computer, your workspace is one of the most controllable factors in upper back pain. A monitor that’s too low forces your head forward, and your upper back muscles have to work constantly to keep your head from dropping. Over hours and days, this leads to the rounded-shoulder, forward-head posture that loads the trapezius and rhomboids far beyond what they’re designed to handle.
A few specific measurements make a real difference. Your monitor’s top line of text should sit at or slightly below eye level, about 50 to 70 centimeters from your face for a standard 24- to 27-inch screen. Your elbows should rest close to your body, bent at roughly 90 degrees, and your keyboard surface should be 1 to 3 centimeters below your elbow height. For someone who is 5’10”, that means a seated desk height of about 25.5 to 28.5 inches. If you use a standing desk at the same height, aim for 42.5 to 45.5 inches.
Getting these numbers right eliminates the most common postural stresses on the thoracic spine. If your current setup doesn’t match, even small adjustments like raising your monitor on a stack of books can reduce the load on your upper back within days.
Exercises That Help
The best approach to persistent upper back pain combines mobility work with strengthening. The thoracic spine is meant to rotate and extend, and when it gets stiff from sitting, pain follows. A few exercises have stronger evidence behind them than most.
Thoracic extension over a foam roller is one of the simplest. Lie with the roller positioned across your mid-back, support your head with your hands, and gently arch backward over the roller. This has been shown to improve both mechanical neck pain and the rounded-shoulder posture that drives upper back strain. Move the roller up or down a segment and repeat to mobilize different levels of the spine.
The Y-lift (sometimes called the Superman variation) targets the muscles that hold your shoulder blades in place. Lying face down, you raise your arms overhead in a Y shape while lifting your chest slightly off the floor. An eight-week program that included this exercise improved forward-head and rounded-shoulder posture in elite swimmers, a group that puts enormous stress on the thoracic spine.
Rotation drills round out the approach. Sidelying thoracic rotation, where you lie on your side with knees bent and rotate your top arm and torso open toward the ceiling, directly targets the rotational stiffness that builds up from desk work. Quadruped thoracic rotation, done on hands and knees with one hand behind your head, works the same pattern from a different angle. These are gentle enough to do daily and effective enough to produce noticeable changes in how your upper back feels within a couple of weeks.
Most upper back pain from muscular or postural causes responds well to consistent movement. The combination of opening up stiff joints, strengthening the muscles between your shoulder blades, and fixing the ergonomic problems that created the issue in the first place resolves the majority of cases without any other intervention.
