Pleurisy is a condition where the lining around the lungs becomes inflamed, causing sharp chest pain that worsens with breathing or coughing1 . This inflammation can lead to complications such as fluid buildup or lung compression, affecting breathing and overall lung function2 . Understanding the types, symptoms, causes, and treatments of pleurisy is essential for timely diagnosis and effective management3 .
Types of Pleurisy
Pleurisy is broadly classified into two main types: dry (fibrinous) pleurisy and wet (exudative) pleurisy2 . Dry pleurisy involves inflammation of the pleural surfaces without significant fluid accumulation2 . A hallmark of dry pleurisy is the presence of a pleural friction rub, a grating or raspy sound heard during breathing caused by the inflamed pleural layers rubbing against each other2 4. In contrast, wet pleurisy is characterized by pleural effusion, which is the accumulation of fluid in the pleural space between the lungs and chest wall2 5. This fluid buildup can compress the lung, leading to respiratory symptoms such as shortness of breath and decreased lung expansion2 5.
Dry pleurisy often causes sharp, localized chest pain due to the inflamed pleura rubbing together, while wet pleurisy may initially relieve pain as fluid separates the pleural layers but can cause breathing difficulties as fluid accumulates6 . Both types require medical evaluation to determine the underlying cause and appropriate treatment2 .
Pleurisy Symptoms
The primary symptom of pleurisy is sharp, pleuritic chest pain that worsens with breathing, coughing, or sneezing2 7. This pain is typically localized to one side of the chest but can sometimes spread to the shoulder or back2 1. The pain is often described as stabbing or sharp and may increase with movement or deep breaths, which can limit respiratory effort and daily activities2 3. Patients may adopt a posture that limits chest movement to reduce pain4 .
Other symptoms associated with pleurisy include:
- Shortness of breath due to lung compression or pain limiting breathing depth1 8
- Persistent cough, which may be dry or productive depending on the cause3 6
- Fever and fatigue, especially if infection is the underlying cause3 6
In cases of wet pleurisy with pleural effusion, symptoms of respiratory compromise such as rapid breathing and difficulty breathing may become more prominent2 5.
Pleurisy causes sharp chest pain that worsens during breathing or coughing. The pain may spread to the shoulder or back and can limit daily activities due to discomfort1 3.
Pleurisy Causes
Pleurisy results from inflammation of the pleura, the thin membrane that lines the lungs and chest cavity, facilitating smooth lung movement during respiration2 5. When the pleura becomes inflamed, the normally smooth surfaces rub against each other, causing pain and sometimes fluid accumulation2 1.
Common causes of pleurisy include:
- Viral infections such as influenza and pleurodynia, which are the most frequent causes7 3
- Bacterial infections, including pneumonia and tuberculosis5 6
- Pulmonary embolism (blood clots in the lungs), a serious cause often associated with pleuritic pain2 74
- Autoimmune diseases like systemic lupus erythematosus and rheumatoid arthritis2 8
- Malignancies such as lung cancer and mesothelioma, which can cause pleurisy through direct pleural involvement or pleural effusion2 5
- Chest trauma or rib fractures causing pleural irritation2 6
- Other conditions including fungal infections, inflammatory bowel disease, sickle cell disease, and certain medications3 5
Pleurisy itself is not contagious, but the infections causing it may be3 .
Pleurisy Risk Factors
Certain factors increase the likelihood of developing pleurisy by predisposing individuals to pleural inflammation or lung disease2 8. These risk factors include:
- Advanced age, which is associated with increased susceptibility to lung infections and chronic diseases2 8
- History of lung infections such as pneumonia or tuberculosis2 8
- Chest trauma or injury that affects the pleura2 8
- Presence of inflammatory or autoimmune diseases like lupus or rheumatoid arthritis2 8
- Smoking, which damages lung tissue and increases infection risk2 8
- Lung cancer or pulmonary scarring from previous lung disease or radiation therapy2 8
Managing these risk factors can help reduce the chance of developing pleurisy2 .
Diagnosing Pleurisy
Diagnosing pleurisy involves a comprehensive clinical evaluation to identify the characteristic symptoms and underlying cause2 9. The process includes:
- Detailed medical history focusing on chest pain characteristics, recent infections, trauma, and risk factors2 9
- Physical examination with auscultation to detect a pleural friction rub, a distinctive grating sound indicating inflamed pleura2 94
- Assessment of vital signs to evaluate severity and presence of infection or respiratory distress2 9
Diagnostic tests commonly used include:
- Chest X-ray to detect lung abnormalities, pleural effusion, or signs of pneumonia and tumors2 95
- Computed tomography (CT) scan for detailed imaging of the pleura and to rule out pulmonary embolism or malignancy2 9
- Ultrasound to identify and assess pleural effusions2 9
- Blood tests such as complete blood count (CBC) and markers of inflammation or infection2 9
- Electrocardiogram (ECG) to exclude cardiac causes of chest pain such as myocardial infarction or pericarditis2 94
- Thoracentesis, a procedure to remove pleural fluid for analysis when effusion is present2 95
- Thoracoscopy for direct visualization and biopsy of pleural tissue in complex cases9
Accurate diagnosis is essential to guide appropriate treatment and exclude other serious conditions2 9.
Pleuritic chest pain is a common presenting symptom and has many causes, which range from life-threatening to benign, self-limited conditions. Pulmonary embolism is the most common potentially life-threatening cause, found in 5 to 20 percent of patients who present to the emergency department with pleuritic pain4 .
Pleurisy Treatment Options
Treatment of pleurisy focuses on relieving pain and addressing the underlying cause2 9. Management strategies include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs) as first-line therapy to reduce pain and inflammation without suppressing respiratory effort2 94
- Corticosteroids may be used if NSAIDs are ineffective or contraindicated2 9
- Antibiotics for bacterial infections such as pneumonia or tuberculosis2 95
- Supportive care for viral pleurisy, including rest and NSAIDs for symptom relief2 9
- Thoracentesis to drain significant pleural effusions, which can relieve lung compression and improve breathing2 95
- Oxygen therapy in cases with respiratory compromise5
- Treatment of pulmonary embolism with anticoagulants or thrombolytic therapy depending on severity5
- Cancer-related pleurisy may require surgery, chemotherapy, or radiation therapy5
Pain control is crucial to enable adequate breathing and prevent complications such as atelectasis (lung collapse) 25. Recovery time varies depending on the cause but often occurs within weeks with proper treatment7 5.
| Treatment Option | Purpose | Notes |
|---|---|---|
| NSAIDs | Pain and inflammation relief | Preferred first-line agent2 9 |
| Corticosteroids | Anti-inflammatory alternative | Used if NSAIDs fail or not tolerated2 9 |
| Antibiotics | Treat bacterial infections | Essential for pneumonia, TB2 5 |
| Thoracentesis | Drain pleural fluid | For symptomatic pleural effusion2 9 |
| Anticoagulants | Treat pulmonary embolism | For blood clot-related pleurisy5 |
Preventing Pleurisy
Preventing pleurisy involves reducing risk factors and managing underlying health conditions that can lead to pleural inflammation2 8. Key preventive measures include:
- Vaccination against respiratory infections such as influenza and pneumonia to reduce infection risk2 6
- Practicing good hygiene and avoiding close contact with sick individuals to prevent contagious infections2 6
- Smoking cessation to improve lung health and decrease susceptibility to lung diseases2 8
- Prompt treatment of respiratory infections and chronic diseases like autoimmune disorders2 8
- Protecting the chest from trauma and injury when possible2
These steps help maintain lung and pleural health, lowering the chance of developing pleurisy2 .

Managing Pleurisy Symptoms
Living with pleurisy involves managing symptoms to maintain comfort and respiratory function while the underlying cause is treated2 5. Important strategies include:
- Taking prescribed pain medications such as NSAIDs or corticosteroids as directed to control chest pain2 9
- Resting and avoiding activities that worsen chest pain or breathing difficulty3 5
- Using breathing techniques or positioning, such as lying on the affected side, to reduce pain during respiration5
- Monitoring for new or worsening symptoms like increased shortness of breath, fever, or cough, and seeking medical care promptly2 5
- Avoiding smoking and exposure to lung irritants to support recovery2 8
Most patients recover fully with appropriate care, but untreated pleurisy can persist or recur, making adherence to treatment and follow-up important2 5.
