Pain in the upper back, particularly between the shoulder blades, is often dismissed as muscle tension. A few hours of poor posture, prolonged sitting, physical exertion, or stress can certainly cause muscular discomfort. But when upper back pain keeps returning despite massage, rest, stretching, or muscle-relaxing medication, it may be worth looking beyond the muscles.
The thoracic spine, which forms the middle portion of the spine, can be a potential source of persistent upper back pain. Structural changes involving the discs, joints, ribs, or nerves can sometimes produce symptoms that feel like ordinary muscular pain.
Understanding the possible source of the pain is an important first step toward choosing appropriate treatment.
Understanding the Thoracic Spine
The thoracic spine consists of 12 vertebrae, extending from the base of the neck to the lower back. It connects with the ribs and plays an important role in supporting the upper body, protecting the spinal cord, and allowing movement of the trunk.
Compared with the cervical and lumbar spine, the thoracic region generally receives less attention when people discuss spinal pain. As a result, persistent pain in the upper or middle back may sometimes be attributed to muscle tightness without a detailed investigation of the spine.
However, thoracic pain can have several potential structural causes.
Thoracic Disc Degeneration and Disc Problems
The discs between the vertebrae act as cushions and help the spine absorb mechanical loads. Like other parts of the spine, thoracic discs can undergo degenerative changes over time.
In some cases, a disc may bulge or herniate and potentially irritate nearby structures. Thoracic disc problems are less common than cervical or lumbar disc problems, but they can cause localised upper or mid-back pain and, depending on the location and severity, nerve-related symptoms.
Not every disc abnormality seen on an MRI is necessarily responsible for pain. Imaging findings need to be interpreted together with symptoms and clinical examination.
Facet Joint Arthritis
Small joints called facet joints connect the vertebrae and help guide spinal movement. Degenerative changes or arthritis in these joints can contribute to localised pain and stiffness.
Thoracic facet-related pain may become more noticeable with certain movements, prolonged positions, or activities that place additional stress on the spine. Because the symptoms can overlap with muscular pain, clinical evaluation can help determine whether the facet joints may be contributing.
Costovertebral Joint Dysfunction
The thoracic vertebrae are closely connected to the ribs through joints called costovertebral and costotransverse joints. These joints allow the ribs to move as part of normal breathing and trunk movement.
Irritation or dysfunction involving these joints can produce pain around the upper or middle back, sometimes close to the shoulder blade or along the rib cage. Such symptoms may be mistaken for muscle strain, particularly when the discomfort develops after repetitive activity, altered posture, or physical exertion.
Postural Kyphosis and Spinal Alignment
The thoracic spine naturally has a gentle forward curve known as kyphosis. When this curvature becomes more pronounced, it may contribute to altered posture and mechanical stress.
Long periods of sitting with the head and shoulders positioned forward can place additional demands on the muscles and joints supporting the thoracic spine. Poor posture does not automatically mean that a person has a structural spinal disorder, but persistent postural changes can contribute to discomfort in some individuals.
Addressing ergonomics, movement habits, mobility, and strengthening can therefore be an important part of managing chronic upper back pain.
Thoracic Nerve-Root Compression
The nerves emerging from the thoracic spine travel around the chest wall. If a nerve root becomes irritated or compressed, symptoms may include localised pain, burning, tingling, numbness, or pain that follows a band-like path around the ribs.
Nerve-related symptoms deserve particular attention because they may require more detailed assessment than routine muscular pain.
Why Treating Only the Muscles May Not Be Enough
Massage, stretching, heat, and muscle-relaxing medication can sometimes provide useful symptom relief. However, if the underlying problem involves a disc, facet joint, rib joint, spinal alignment, or nerve irritation, repeatedly treating muscle tightness alone may not address the contributing factor.
This does not mean that every case of upper back pain requires imaging or specialised treatment. Many episodes of back pain are not caused by serious structural disease and may improve with conservative care.
But persistent, recurrent, worsening, or unexplained pain deserves appropriate evaluation rather than being automatically labelled as muscle tension.
How is Thoracic Spine Pain Diagnosed?
Diagnosis generally begins with a detailed medical history and physical examination. A clinician may assess spinal movement, posture, muscle strength, sensation, reflexes, and areas of tenderness. The pattern of pain and any associated neurological symptoms can provide important clues.
When clinically indicated, imaging may be recommended.
- X-rays can help evaluate bone structure, alignment, and degenerative changes.
- MRI provides greater detail of the discs, spinal cord, nerves, and other soft tissues.
The objective is not simply to find an abnormality on a scan, but to determine whether the finding corresponds with the patient’s symptoms and examination.
Can NSSDT Be Considered for Thoracic Spine Problems?
For appropriately selected patients with certain spinal conditions, Non-Surgical Spinal Decompression Treatment (NSSDT) may be considered as part of a non-surgical treatment program.
At ANSSI Wellness, NSSDT uses a computer-controlled treatment table and harness to apply controlled traction to selected spinal segments. The treatment is intended to modify mechanical loading around the targeted area. Depending on the patient’s condition, it may be combined with physiotherapy, strengthening exercises, posture correction, and activity guidance.
However, Non-Surgical Spinal Decompression Treatment is not suitable for every cause of thoracic pain. It should not be presented as a guaranteed solution or as a treatment that reverses spinal degeneration. A proper assessment is necessary before deciding whether decompression-based treatment is appropriate.
