Pleurisy
What is Pleurisy?
Pleurisy is inflammation of the pleura, the thin tissue that lines your lungs and chest cavity. The pleura has two layers with a small amount of fluid between them. When these layers become inflamed, they rub together during breathing, causing sharp chest pain.
This condition can affect anyone, though it often develops alongside other health issues. The pain is typically worse when you take deep breaths, cough, or sneeze. Pleurisy may occur on one or both sides of your chest and can range from mild to severe.
Most cases of pleurisy improve with treatment of the underlying cause. The condition itself is not life-threatening, but it can signal other health problems that need attention. Early diagnosis helps identify the root cause and prevent complications.
Symptoms
- Sharp, stabbing chest pain that worsens with breathing, coughing, or sneezing
- Pain on one or both sides of the chest
- Shortness of breath or shallow breathing to avoid pain
- Dry cough
- Fever and chills if infection is present
- Pain that radiates to the shoulder or back
- Difficulty taking deep breaths
- Rapid breathing to minimize discomfort
Some people with mild pleurisy may not notice symptoms right away. Others experience severe pain that makes normal activities difficult. The intensity of symptoms often depends on the underlying cause and severity of inflammation.

Causes and risk factors
Pleurisy develops when the pleura becomes inflamed due to infection, injury, or other medical conditions. Viral infections are the most common cause, including flu, COVID-19, and other respiratory viruses. Bacterial infections like pneumonia can also trigger pleural inflammation. Less commonly, fungal or parasitic infections may be responsible.
Other causes include autoimmune conditions like lupus or rheumatoid arthritis, where the immune system attacks healthy tissue. Pulmonary embolism, a blood clot in the lung, can cause sudden pleurisy. Chest injuries, certain medications, and cancer affecting the lungs or pleura may also lead to inflammation. Risk factors include smoking, recent respiratory infections, autoimmune disorders, and exposure to asbestos or other lung irritants.
How it's diagnosed
Doctors diagnose pleurisy by listening to your chest with a stethoscope. They listen for a rubbing sound called a pleural friction rub, which occurs when inflamed pleural layers move against each other. Your doctor will also ask about your symptoms, medical history, and recent illnesses.
Specialized tests help identify the underlying cause of pleurisy. Chest X-rays or CT scans can show fluid buildup or lung problems. If fluid has accumulated between the pleural layers, a procedure called thoracentesis may remove a sample for analysis. Blood tests can detect infections, inflammation markers like Complement Component C3, and autoimmune conditions. Talk to a doctor about which tests are right for your situation.
Treatment options
- Rest and avoid activities that worsen chest pain
- Anti-inflammatory medications like ibuprofen to reduce pain and swelling
- Antibiotics if bacterial infection is the cause
- Antiviral medications for certain viral infections
- Treating underlying conditions like autoimmune disorders
- Pain management with prescribed medications if over-the-counter options are insufficient
- Lying on the painful side may help reduce discomfort
- Deep breathing exercises once pain improves to prevent lung complications
- Draining excess fluid if significant buildup occurs
- Addressing lifestyle factors like smoking cessation
Frequently asked questions
Pleurisy causes sharp, stabbing chest pain that feels like a knife. The pain gets worse when you breathe deeply, cough, sneeze, or move. Many people describe it as a sudden, intense sensation on one side of the chest. The pain may improve when you hold your breath or lie on the affected side.
Pleurisy duration depends on the underlying cause. Viral pleurisy often improves within a few days to two weeks with rest and pain relief. Bacterial infections may take longer and require antibiotics. Pleurisy caused by chronic conditions like autoimmune disorders may persist or recur without proper treatment of the root cause.
Mild viral pleurisy may resolve on its own with rest and over-the-counter pain medication. However, you should always see a doctor to identify the cause. Pleurisy caused by bacterial infection, blood clots, or other serious conditions requires medical treatment. Ignoring symptoms can lead to complications like fluid buildup or lung scarring.
Pleurisy itself is not contagious, but the infections that cause it may be. If a virus or bacteria triggered your pleurisy, you could spread that infection to others. Practice good hygiene by washing your hands frequently and covering your mouth when coughing. Pleurisy from non-infectious causes like autoimmune disorders or injuries cannot spread to other people.
Blood tests help identify the underlying cause of pleurisy rather than the inflammation itself. Complement Component C3 levels may be elevated in inflammatory conditions affecting the pleura. Complete blood counts can reveal infections or inflammation. Additional tests may check for autoimmune markers, blood clotting issues, or specific infections depending on your symptoms.
You should avoid strenuous exercise during active pleurisy because deep breathing and physical activity worsen chest pain. Rest is important while your body heals. Once symptoms improve and your doctor approves, gentle activity can resume gradually. Deep breathing exercises may be recommended to prevent lung complications and restore normal breathing patterns.
Pneumonia is an infection of the lung tissue itself, while pleurisy is inflammation of the lining around the lungs. Pneumonia often causes fever, productive cough with mucus, and fatigue. Pleurisy causes sharp chest pain that worsens with breathing. However, bacterial pneumonia can cause pleurisy as a complication, so the two conditions sometimes occur together.
Most cases of pleurisy heal completely without lasting effects when treated properly. However, severe or untreated pleurisy can lead to complications. Thick scar tissue may form between the pleural layers, restricting lung expansion. Large fluid collections may need drainage to prevent lung collapse. Early treatment of the underlying cause helps prevent permanent damage.
Seek immediate medical attention for any new or severe chest pain. Sharp pain that worsens with breathing could indicate pleurisy or other serious conditions. Go to the emergency room if you have chest pain with shortness of breath, rapid heartbeat, coughing up blood, or fever above 102 degrees. Even mild chest pain deserves evaluation to rule out serious causes.
Preventing pleurisy means reducing your risk of the conditions that cause it. Get vaccinated against flu, pneumonia, and COVID-19 to prevent respiratory infections. Quit smoking to protect your lungs from damage and inflammation. Manage chronic conditions like autoimmune disorders with your doctor. Practice good hygiene during cold and flu season to avoid viral infections.
