Thoracic pain (upper back pain) is usually muscular and posture-related. It’s less common than neck or low back pain — but red flags matter more here, because some serious chest and abdominal problems can refer to the mid-back.
What Is Upper Back Pain?
The thoracic spine — the part of your back between your neck and lower back — is the most stable section of the spine. Pain here is less common than neck or low back pain, with around 15–35% of adults reporting it in any given year.
Most thoracic pain is mechanical: muscle tightness, joint stiffness, or a strain. Common drivers are prolonged sitting, heavy backpacks, repetitive lifting and stress-related muscle tension.
Because the thoracic spine sits between vital organs, red flags here matter. Heart, lung, gallbladder, oesophagus and aorta problems can all refer pain to the mid-back, so a careful history is important.
Common Causes
- Mechanical thoracic pain (Common): Diffuse aching between the shoulder blades or along the spine, worse with sustained postures.
- Costochondritis and rib joint pain (Common): Sharp, well-localised pain at a rib joint, often reproducible by pressing on the spot. Worsens with deep breath or twist.
- T4 / interscapular syndrome (Postural): Mid-back pain often with vague arm or hand symptoms; commonly desk-related.
- Thoracic disc problems (Specific): Uncommon. May cause band-like pain around the chest or, rarely, leg symptoms.
- Vertebral compression fracture (Bone): Sudden mid-back pain in older adults, especially with osteoporosis, after minor strain or fall.
- Visceral referred pain (Referred): Heart, gallbladder, pancreas, aorta and lung problems can refer pain here.
Treatments
- NSAIDs for short-term relief
- Trigger-point injections for refractory muscular pain
- Bisphosphonates / vertebroplasty (selective) for compression fractures
- Treat referred causes (cardiac, GI) directly
- Spinal manual therapy combined with exercise
- Thoracic mobility and scapular strengthening
- Workplace ergonomic adjustments
- Graded aerobic activity
- Stress and tension management
- Pacing for chronic episodes
- Sleep optimisation
Red Flags — When to Seek Care Now
- New thoracic pain in someone over 50 with osteoporosis or steroid use
- Crushing or pressure-like pain with sweating, shortness of breath, or arm symptoms
- Tearing pain radiating to the back
- Fever, chills, IV drug use, immunosuppression with new spinal pain
- Unexplained weight loss, history of cancer with new back pain
- Saddle numbness, leg weakness, or bowel/bladder changes
Dos and Don’ts
- Move every 30–40 minutes if you sit a lot
- Add daily thoracic mobility — extensions, rotations
- Strengthen scapular and core muscles
- Use heat for muscular tightness
- Don’t ignore mid-back pain with chest, breathing or abdominal symptoms
- Don’t assume any sharp pain on breathing is just muscular — get rib and lung issues ruled out
Frequently Asked Questions
Why does my upper back hurt every time I work at my computer?
Sustained postures load the thoracic muscles and joints. The fix is rarely “sit perfectly upright” — it’s variety, frequent movement and stronger postural muscles.
Is sharp pain when I take a deep breath dangerous?
Costochondritis and rib joint pain can cause this. But chest pain with deep breaths can also signal a lung clot or pleurisy — if it’s new, get evaluated promptly.
