Synopsis
Use pleuritic pain as a localisation clue rather than a diagnosis, rapidly exclude pulmonary embolism, pneumothorax, pneumonia, acute coronary disease and aortic or pericardial emergencies, then treat the established cause safely.
- Pleuritic pain is sharp and worsened by inspiration or cough, reflecting movement of pain-sensitive pleura, pericardium, chest wall or nearby structures; lung parenchyma itself is largely insensitive.
- Pulmonary embolism, pneumothorax and pneumonia are key thoracic causes, but acute coronary syndrome, pericarditis and acute aortic syndrome can present atypically and must remain in the first assessment.
- Sudden pain with dyspnoea, venous-thromboembolism risk or haemoptysis requires a Wells-led PE pathway; neither reproducible tenderness nor a normal saturation safely excludes embolism.
- Sudden unilateral pain with reduced breath sounds suggests pneumothorax; physiological compromise with obstructive shock requires immediate decompression before imaging.
- Fever, cough, focal crackles or bronchial breathing suggests pneumonia, while a pleural rub is specific for inflamed pleural surfaces but often transient.
- Obtain ECG in acute chest pain even when symptoms sound pleuritic, because ischaemia and pericarditis change immediate management.
- Chest radiography identifies pneumothorax, consolidation and effusion but can be normal in embolism and early pleural inflammation.
- Analgesia supports ventilation and cough, but symptom improvement must not be used as proof of a benign musculoskeletal cause.
Key red flags
Sudden pleuritic pain, unexplained breathlessness, tachycardia, haemoptysis, syncope or hypoxaemia with thrombosis risk raises probability. A normal chest radiograph, normal ECG or reproducible tenderness cannot independently exclude it.
Abrupt unilateral pain with dyspnoea, reduced air entry and hyperresonance suggests pleural air, especially with smoking, underlying lung disease, trauma or a recent procedure. Hypotension, severe distress or rapidly worsening physiology suggests tension.
Central or left-sided pain that improves sitting forward, a pericardial rub and widespread ST-segment or PR changes supports pericarditis. Effusion, raised JVP, hypotension or pulsus paradoxus raises tamponade risk.
Age, vascular risk, exertional component, autonomic symptoms, tearing radiation, neurological deficit, pulse asymmetry or new aortic regurgitation should override a superficially pleuritic description and trigger the relevant emergency pathway.
Investigation priorities
Identify respiratory failure, shock or another need for immediate monitored care.
Management branches
Any new pleuritic chest pain before a benign cause is secure.
- Use ABCDE, measure oxygenation and haemodynamics, obtain ECG and examine for asymmetric air entry, infection, venous thrombosis, pericardial disease and aortic signs.
- Treat clinically unstable tension pneumothorax immediately; activate the relevant emergency pathway for shock, acute coronary disease, tamponade, sepsis or suspected acute aortic syndrome.
- Obtain chest radiography when stable enough and use focused ultrasound if it can answer an urgent pleural or cardiac question without delaying definitive care.
- Only after dangerous causes are reasonably excluded should reproducible tenderness or a viral syndrome be accepted as the working explanation.
Stable observations, negative emergency assessment and findings supporting chest-wall or uncomplicated viral pleural pain.
- Use appropriate simple analgesia, maintain comfortable deep breathing and mobility, and treat cough or the confirmed underlying illness without unnecessary antibiotics.
- Explain the working diagnosis and the limits of current testing, particularly that recurrence or new breathlessness changes the assessment.
