Upper back pain (thoracic pain): causes and treatment

Upper back pain (thoracic pain) often feels like an ache, sharp twinge, stiffness, or rib discomfort around your mid-back. Many people notice it with sitting, lifting, twisting, deep breathing, gym work, or long screen time.

Sometimes the pain comes from muscles or posture. However, it can also come from the joints of the thoracic spine, the ribs, or nearby nerves. If you want deeper condition-specific guidance, start with common causes of upper back pain or explore related thoracic conditions below.

Additionally, thoracic symptoms can overlap with neck, shoulder, and rib problems. These guides may help you compare patterns: spinal pain, shoulder pain, and arm pain causes.

If your pain sits more toward the front of the ribs or chest wall, you may also find these pages useful: costochondritis and side strain.

Why does upper back pain happen?

Upper back pain usually builds up from a few common drivers. First, long periods in one posture can overload the mid-back and rib joints. Next, sudden increases in training load (or heavy lifting) can irritate muscles, joints, or rib attachments. Finally, falls or direct impact can bruise ribs or strain the thoracic spine.

• Joint irritation: thoracic facet joints can become stiff or painful with rotation and extension.
• Rib-related pain: rib joints and chest wall tissues can hurt with deep breathing, coughing, or twisting.
• Muscle overload: mid-back muscles can tighten with desk work, overhead work, or repetitive tasks.
• Posture + fatigue: shoulder blade control can drop when you are tired, which increases mid-back strain.

People Also Ask: Why does my upper back hurt when I breathe? Many people feel sharper pain with deep breaths when rib joints or chest wall tissues become irritated. A physiotherapist can assess your ribs, thoracic spine, breathing mechanics, and posture to guide safe exercise and symptom control.

Common thoracic pain symptoms

• Stiffness or aching between the shoulder blades
• Pain with trunk rotation, reaching, or overhead work
• Rib or chest wall tenderness that changes with movement or breath
• Worse symptoms after prolonged sitting or driving

For posture-driven cases, these pages can support your rehab plan: posture correction and posture exercises. If you suspect your symptoms link to nerve or circulation compression, read thoracic outlet syndrome.

How a physiotherapist may assess thoracic pain

A physiotherapist will usually start by confirming whether your pain behaves like a musculoskeletal issue. Then they may check your posture, thoracic mobility, rib movement, breathing pattern, shoulder blade control, and strength. If your symptoms suggest a non-musculoskeletal cause, they will recommend the right next step quickly.

Thoracic pain treatment options

Most non-serious upper back pain responds well to a staged plan. Early on, the aim is to settle irritation and restore comfortable movement. After that, strengthening and load management help reduce flare-ups.

• Education + pacing: adjust lifting, sitting breaks, and training load while symptoms settle.
• Mobility work: gentle thoracic rotation and extension drills to reduce stiffness.
• Strength work: build endurance in mid-back, shoulder blade, and trunk muscles.
• Hands-on care (when suitable): may help short-term pain and movement, alongside exercise.

Thoracic spine red flags

Most upper back pain is straightforward. However, thoracic pain can also link with more serious conditions. For that reason, treat the following as red flags and arrange an urgent medical assessment if they apply.

Red flags

• History of cancer, drug abuse, HIV, immunosuppression, or prolonged use of corticosteroids.
• Fever, chills, unexplained weight loss, or recent bacterial infection.
• Pain that is:
  • Constant, severe, and getting worse.
  • Non-mechanical with no relief from rest or position changes.
  • Unchanged despite appropriate care for 2–4 weeks.
  • Associated with marked morning stiffness (for example, inflammatory arthritis patterns).
• Recent major trauma (car accident, fall from height) or visible spinal deformity.
• Minor trauma or heavy lifting in people with known osteoporosis.
• New back pain starting before age 20 or after age 50.
• Severe or worsening neurological symptoms (weakness, numbness, altered reflexes).

If you have any of these red flags, seek urgent medical assessment.

What to do next

Start by keeping your movement gentle and regular. Next, reduce activities that flare your pain for a few days, rather than stopping everything. If your pain keeps returning, spreads into your chest or arm, or limits sleep and work, a physiotherapist can assess the driver and guide a safe plan.
