Could upper back pain when coughing be pneumonia or a blood clot in my lung?

If you’re asking “why does my upper back hurt when I cough,” you’re not alone. Pain in the upper back or between the shoulder blades with coughing can have many causes. While most are harmless, some—like pneumonia or a pulmonary blood clot (pulmonary embolism)—require prompt medical attention. This guide explains the possibilities, key warning signs, and next steps.

Why does my upper back hurt when I cough?

Coughing creates a sudden increase in pressure inside your chest. That force can irritate or strain structures in the back, including:

• Muscles and tendons
• Small joints between the ribs and spine (costovertebral joints)
• Nerves exiting your spine
• The lining of your lungs (pleura)

The exact source of pain determines how severe it feels and whether other symptoms appear.

Common, less serious causes

1. Muscle strain

   • Overuse from heavy lifting or poor posture
   • Repeated coughing that fatigues intercostal muscles
   • Localized soreness that improves with rest, heat, or NSAIDs

2. Rib joint irritation (costovertebral strain)

   • Minor injury or jarring movement
   • Sharp pain worsens with deep breaths or twisting
   • Tenderness to touch over the affected joints

3. Nerve irritation

   • Pinched or inflamed nerve root in the upper spine
   • Burning or shooting pain radiating around the chest wall
   • Often linked to arthritis or disc issues

4. Bronchitis or upper respiratory infections

   • Viral or bacterial infections inflaming airways
   • Persistent cough with mild aching between shoulder blades
   • Usually improves within 1–3 weeks

These causes are common and often resolve on their own with home care: rest, pain relievers, gentle stretching, and staying hydrated.

Could it be pneumonia?

Pneumonia is an infection of the lung tissue. When the lung’s air sacs fill with fluid or pus, the lining (pleura) can become irritated, causing pain that may be felt in the back when coughing.

Key pneumonia signs:

• Fever, chills, or sweats
• Productive cough (yellow, green, or bloody mucus)
• Shortness of breath or rapid breathing
• Chest pain sharp or stabbing, often worse with deep breaths or cough
• Fatigue, muscle aches, headache
• In older adults: confusion, lower than normal body temperature

Why back pain appears:

• Lower lung lobes sit close to the back
• Inflammation or infection there transmits pain to muscles and joints in that area

When to suspect pneumonia:

• You have fever plus a productive cough
• You’re short of breath or breathing very fast
• You feel unusually weak or disoriented

If you suspect pneumonia, see a healthcare provider. They may order a chest X-ray, blood tests, or sputum culture, and prescribe antibiotics if bacterial.

Could it be a blood clot in my lung (pulmonary embolism)?

A pulmonary embolism (PE) happens when a blood clot—often from the leg—travels to and lodges in lung arteries. Though back pain is less common than chest pain, it can occur, especially if the clot is in a lung area near your back.

Warning signs of PE:

• Sudden, unexplained shortness of breath
• Sharp, stabbing chest or upper back pain, often worse with deep breath or cough
• Rapid heartbeat or palpitations
• Lightheadedness or fainting
• Coughing up blood (even small streaks)
• Leg swelling, warmth, or pain (signs of deep vein thrombosis)

Risk factors:

• Recent long flight or car ride without movement
• Recent surgery, especially hip or knee
• Cancer, or taking certain cancer medications
• Prolonged bed rest or immobility
• Hormone therapy, birth control pills, or pregnancy

Pulmonary embolism is life-threatening. If you have these symptoms, seek emergency care immediately.

Other possible causes

• Pleurisy: Inflammation of the lung lining causes sharp, localized pain. Often viral or from pneumonia.
• Shingles (herpes zoster): Before the rash appears, you may feel intense burning or shooting pain under one side of your ribcage.
• Spinal issues: Osteoarthritis or degenerative disc disease in the thoracic spine can flare with coughing.
• Gallbladder or pancreatic problems: Rarely, referred pain from gastrointestinal issues is felt between the shoulder blades.

When to worry: red flags

Contact a medical professional or seek urgent care if you experience any of the following:

• Severe, unrelenting pain
• High fever (above 100.4°F / 38°C)
• Difficulty breathing or rapid breathing
• Coughing up blood
• Lightheadedness, confusion, or fainting
• Swelling, pain, or redness in one leg
• Chest pain that radiates to your shoulder, jaw, or arm

Even if your symptoms seem mild, it’s always safer to check. You can start with a free, online symptom check, using the doctor approved Ubie Symptom Checker.

Self-care tips for mild pain

If you’ve ruled out emergency conditions, you can usually manage mild upper back pain with:

• Over-the-counter pain relievers (acetaminophen, ibuprofen)
• Warm compresses or heating pads to relax tight muscles
• Gentle stretching: shoulder rolls, chest stretches against a wall
• Posture awareness: sit and stand upright, avoid slumping
• Staying hydrated and using cough suppressants or expectorants as directed

Avoid strenuous activity until pain subsides. If pain persists beyond two weeks or worsens, see your doctor.

Next steps and when to see a doctor

1. Monitor your symptoms: note changes in pain, breathing, temperature, cough, or leg swelling.
2. Use the Ubie Symptom Checker for guidance on urgency and possible causes.
3. Schedule a primary care visit if:
   • Pain is moderate but not improving
   • You have risk factors for pneumonia or blood clots
   • You develop new symptoms (fever, shortness of breath, leg pain)

If you ever feel your condition could be life-threatening—especially with chest/back pain plus breathing trouble or fainting—call emergency services or go to the nearest emergency department.

Bottom line

Upper back pain when coughing is often due to muscle strain, joint irritation, or a simple respiratory infection. However, it can also signal pneumonia, pleurisy, or a serious blood clot. Watch for warning signs, manage mild pain at home, and don’t hesitate to get professional help if you’re unsure.

Remember, you’re not alone: try a free, online symptom check, using the doctor approved Ubie Symptom Checker, and always speak to a doctor about anything that could be life-threatening or serious.
