When most people talk about back pain, they mean the low back. When they talk about neck pain, they mean the cervical spine. The thoracic spine — the long stretch of 12 vertebrae between the two — gets ignored, even though it carries your rib cage, anchors your shoulder mechanics, and produces some of the most frustrating mid-back pain we see. It also happens to be the region of the spine where serious medical conditions are most likely to hide behind ordinary-looking pain.

I am Colin Bouma, an FCAMPT-certified physiotherapist (the highest manual therapy designation in Canada) practising on MacLeod Trail SW. This is the 2026 update to one of our most-read posts, rebuilt around current evidence — and tightened around something the original undersold: the importance of the red-flag screen in thoracic pain.

What the Thoracic Spine Actually Does

The thoracic spine consists of 12 vertebrae (T1–T12), each attached to a pair of ribs. Its job is partly mobility — rotation, extension, side bending — and partly stability, anchoring the rib cage and protecting the heart and lungs. Compared to the neck and low back, the thoracic spine moves less but matters more for breathing mechanics, shoulder elevation, and load transfer between the upper and lower body.

How Common Is Thoracic Spine Pain?

Less studied than neck or low back pain, but not uncommon. A systematic review by Briggs and colleagues found point-prevalence estimates of thoracic spine pain ranging from 4–72% across studies, with 1-year prevalence between 3.5–35% (Briggs, Smith, Straker, & Bragge, 2009). The wide range reflects different populations and definitions, but the bottom line: a meaningful share of adults will have thoracic spine pain in any given year — they just usually call it "mid-back" or "between the shoulder blades."

What Causes Thoracic Spine Pain?

1. Mechanical thoracic and costovertebral joint pain

The most common scenario: sustained static loading (desk work, driving, parenting a small human all day) plus a sudden movement (a hard sneeze, an awkward reach, a lift you would not normally try) producing focal mid-back pain, often near a rib joint. Sometimes the pain wraps around the chest along a rib, which can be alarming until it is clearly mechanical.

2. Muscle pain and trigger points

Rhomboids, mid and lower trapezius, erector spinae, and serratus posterior superior all produce mid-back symptoms when overloaded or chronically sensitized.

3. Disc-related pain (less common but real)

Thoracic disc herniations are far less common than cervical or lumbar ones, but they happen. When they do, they can produce focal pain or, in serious cases, neurological symptoms below the level of the herniation. Most thoracic disc findings on imaging are incidental.

4. Inflammatory and structural conditions

Ankylosing spondylitis and other spondyloarthropathies, severe thoracic kyphosis (especially in older adults with osteoporosis-related compression fractures), and scoliosis can all contribute.

5. Postural / sustained loading — with an honest caveat

You have probably been told that "thoracic kyphosis from slouching" is the cause of your mid-back pain. The evidence is more nuanced than that. Mild-to-moderate kyphosis is common in pain-free adults; severe kyphosis (typically from compression fractures or genuine structural change) can drive symptoms. For most patients with mid-back pain from desk work, the problem is sustained static loading and deconditioning — not the shape of your spine. Movement variety, capacity, and breaks matter more than chasing a specific posture (see our posture post).

Thoracic Pain Red Flags: Why This Matters More Than Cervical or Lumbar

The thoracic region houses your heart, great vessels, lungs, and many of the visceral organs that can refer pain to the mid-back. Thoracic pain is also on the international list of red flags for serious spinal pathology — particularly vertebral fracture and malignancy (Finucane et al., 2020).

See your physician or attend the emergency department if your thoracic pain comes with any of:

•      Severe sudden chest or upper back pain, especially if "ripping" or "tearing" in quality — possible aortic dissection (call 911).

•      Mid-back pain with chest pressure, shortness of breath, sweating, or arm or jaw discomfort — possible cardiac (call 911).

•      Thoracic pain following a fall, particularly in adults over 65 or with osteoporosis — possible vertebral fracture.

•      Unexplained weight loss, night sweats, fevers, or a history of cancer alongside new thoracic pain.

•      Steady, progressive thoracic pain that does not change with position or movement, especially at night.

•      Neurological symptoms below the level of the pain — leg weakness, sensation changes, bowel or bladder changes.

•      Mid-back pain with cough, fever, or pleuritic features — possible respiratory infection or pulmonary embolism.

None of these mean you definitely have something serious. They mean a clinician with the ability to investigate further should see you. We screen for all of them at the first appointment.

What the Evidence Says About Treatment

Once serious pathology is screened out, mechanical thoracic spine pain generally responds well to physiotherapy. A 2024 systematic review and meta-analysis of 18 randomized controlled trials and 914 patients found that thoracic spine manipulation produces short-term improvements in pain, range of motion, and disability for patients with neck pain — and the same principles apply to mechanical thoracic pain itself (Yang et al., 2024). Combined with progressive exercise, the effects are larger and more durable.

Treatment that earns its place:

•      Thoracic mobilization and selective manipulation to restore segmental motion.

•      Soft tissue work on the paraspinal and scapular muscles.

•      Progressive strengthening — mid and lower trapezius, rhomboids, posterior chain, deep paraspinals.

•      Thoracic mobility drills — open-book rotations, prone Y-T-W exercises, foam roller extensions over a movable hinge point.

•      Breathing mechanics work, especially in patients with high upper-chest breathing patterns.

•      Load management and movement variety — the most useful long-term habit changes.

What an Honest Treatment Plan Looks Like

1.     Red-flag screen first. History, vital signs where indicated, neurological exam, palpation. Thoracic pain is the spinal region where serious pathology is most likely to hide.

2.     Identify the actual driver. Facet, costovertebral, rib, muscle, disc, referred pain from organs, or load-tolerance problem from sustained loading. The plan differs depending.

3.     Targeted manual therapy. Thoracic mobilization or selective manipulation, rib mobilization, and soft tissue work — used to reduce sensitivity so loading can progress.

4.     Progressive loading. Real strength work for the mid back, scapular stabilizers, and posterior chain — not a sheet of band rows.

5.     Movement variety and breathing retraining. Microbreaks during long sitting, position changes, and breathing mechanics work where indicated.

6.     Outcome tracking. Pain scores, range of motion measurements, and function-based goals — measured, not guessed.

Home Strategies That Actually Help

•      Move every 30–45 minutes during static work. Stand, stretch, rotate, walk briefly.

•      Strength-train twice a week. Rows, face pulls, deadlifts, and overhead pressing work the muscles around the thoracic spine.

•      Foam roller thoracic extensions — useful for many patients but skip if you have known osteoporosis or have not been screened for vertebral fragility.

•      Wall slides, open-book rotations, and prone Y-T-W exercises for mobility.

•      Breathing practice — slow nasal inhale 4 seconds, exhale 6 seconds, repeated for a few minutes.

•      Sleep enough and manage stress; both load the thoracic and rib region through breathing pattern changes.

How We Treat Thoracic Spine Pain at Our Calgary Clinic

7.     Thorough assessment with red-flag screen. We do not skip this step. Thoracic pain deserves more diagnostic care than its reputation suggests.

8.     Skilled manual therapy. Thoracic and rib mobilization, selective manipulation where indicated, and soft tissue work — delivered as part of a plan, not as a one-off "crack the back."

9.     Real strength and mobility programs. Built to fit your training, your job, and your goals.

10.  Coordination with your physician. When imaging, bone density assessment, or further investigation is appropriate, we coordinate. When the pain is mechanical, we treat it.

11.  Outcome tracking. Validated tools and functional goals so progress is measured against something concrete.
