7 Common Pleurisy Symptoms You Should Never Ignore

Pleurisy, also known as pleuritis, is an inflammation of the pleura—the thin tissue layers that line the lungs and chest cavity. When these membranes become inflamed, they rub against each other during breathing, causing sharp, stabbing pain. Understanding the symptoms of pleurisy is crucial for early detection and proper medical care. This condition can range from mild discomfort to severe pain that significantly impacts daily activities.

While pleurisy can develop suddenly or gradually, recognizing its hallmark symptoms can help you seek timely medical attention. The characteristic chest pain associated with this condition is often distinctive, making it easier to identify compared to other respiratory issues. Below, we explore the most common symptoms of pleurisy that you should be aware of.

1. Sharp, Stabbing Chest Pain

The most distinctive symptom of pleurisy is a sharp, stabbing pain in the chest that worsens with breathing. This pain occurs because the inflamed pleural layers rub against each other when the lungs expand and contract. The pain is typically located on one side of the chest, though it can occasionally affect both sides.

This pleuritic chest pain has several characteristic features:

• Intensifies when taking deep breaths, coughing, or sneezing
• Improves when holding your breath or applying pressure to the painful area
• May feel like a knife-like sensation that comes suddenly
• Can range from mild discomfort to severe, debilitating pain

Many patients describe the pain as feeling worse during physical activity or when lying on the unaffected side. The pain may also radiate to the shoulders or back, making it sometimes difficult to pinpoint the exact location.

2. Shortness of Breath

Difficulty breathing, or dyspnea, is a common symptom that accompanies pleurisy. This occurs because the pain associated with breathing causes patients to take shallow breaths to avoid triggering the sharp chest pain. As a result, the body doesn’t receive adequate oxygen, leading to feelings of breathlessness.

Shortness of breath in pleurisy may manifest as:

• Rapid, shallow breathing patterns
• Feeling unable to take a full, deep breath
• Sensation of air hunger or inability to get enough oxygen
• Worsening breathlessness during physical exertion

In some cases, if fluid accumulates between the pleural layers (pleural effusion), breathing difficulties can become more pronounced. This is because the fluid takes up space in the chest cavity, preventing the lungs from fully expanding.

3. Persistent Dry Cough

A dry, non-productive cough is frequently reported by individuals with pleurisy. This cough develops as the body attempts to clear the airways and responds to the irritation of the inflamed pleural membranes. Unlike productive coughs that bring up mucus, a pleurisy-related cough typically doesn’t produce phlegm.

The cough associated with pleurisy is particularly problematic because:

• Each coughing episode triggers intense chest pain
• It can be persistent and difficult to suppress
• May worsen at night, disrupting sleep
• Can lead to a vicious cycle where coughing causes pain, which triggers more coughing

Patients often find themselves trying to suppress the urge to cough, which can be uncomfortable and may lead to additional respiratory complications if not properly managed.

4. Fever and Chills

When pleurisy is caused by an infection, fever is a common accompanying symptom. The body raises its temperature as part of the immune response to fight off bacteria, viruses, or other pathogens causing the pleural inflammation. Fever associated with pleurisy can range from low-grade to high-grade, depending on the underlying cause.

Temperature-related symptoms may include:

• Fever ranging from 100°F (37.8°C) to 104°F (40°C) or higher
• Alternating episodes of chills and sweating
• Night sweats that may soak bedding
• General feeling of being feverish or overheated

If pleurisy is caused by viral infections like influenza or by bacterial pneumonia, fever may be one of the first symptoms to appear, sometimes even before the characteristic chest pain develops.

5. Pain That Radiates to the Shoulder or Back

While chest pain is the primary symptom of pleurisy, the discomfort often doesn’t stay confined to the chest area. Many patients experience referred pain that extends to the shoulders, particularly the shoulder blade area, or to the upper back. This occurs because the nerves that supply the pleura also connect to these regions.

Radiating pain characteristics include:

• Sharp or aching sensation in the shoulder, especially when breathing deeply
• Pain that travels from the chest to the upper or middle back
• Discomfort that may be mistaken for muscle strain or shoulder problems
• Pain patterns that follow the same breathing-related triggers as chest pain

This referred pain can sometimes confuse the diagnosis, as patients may initially attribute the shoulder or back pain to musculoskeletal issues rather than a respiratory condition.

6. Rapid, Shallow Breathing

Tachypnea, or abnormally rapid breathing, commonly occurs in pleurisy as the body attempts to compensate for reduced oxygen intake. Because deep breathing causes severe pain, patients instinctively take quick, shallow breaths to minimize discomfort. This breathing pattern, however, is less efficient at oxygen exchange.

Signs of altered breathing patterns include:

• Breathing rate exceeding 20 breaths per minute at rest
• Visible chest movement that appears quick and shallow
• Feeling unable to establish a comfortable breathing rhythm
• Increased breathing rate during conversation or minimal activity

This symptom can be particularly concerning because inadequate oxygenation may lead to fatigue, dizziness, and other complications. In severe cases, rapid shallow breathing can contribute to anxiety, which further exacerbates the breathing difficulties.

7. Fatigue and General Weakness

Extreme tiredness and general malaise are common yet often overlooked symptoms of pleurisy. The body expends significant energy fighting the underlying infection or inflammation, while the pain and breathing difficulties prevent restful sleep. This combination leads to pronounced fatigue that can interfere with daily activities.

Fatigue in pleurisy patients typically presents as:

• Persistent exhaustion that doesn’t improve with rest
• Lack of energy to perform routine tasks
• Muscle weakness and general feeling of being unwell
• Reduced stamina and exercise tolerance
• Mental fog or difficulty concentrating due to poor sleep and discomfort

The combination of pain, impaired breathing, potential fever, and sleep disruption creates a perfect storm for debilitating fatigue. Many patients report that this exhaustion is one of the most challenging aspects of dealing with pleurisy, as it affects their ability to work, care for themselves, and maintain normal routines.

Main Causes of Pleurisy

Understanding what causes pleurisy can help in prevention and early recognition. The condition can result from various underlying health issues:

Viral Infections: The most common cause of pleurisy is viral infections, including influenza, respiratory syncytial virus (RSV), and other common viruses. These infections can directly inflame the pleural membranes or cause inflammation as a complication of the illness.

Bacterial Infections: Bacterial pneumonia is a frequent culprit, where the infection in the lungs spreads to the pleural space. Tuberculosis is another bacterial cause, though less common in developed countries. Bacterial pleurisy often presents with more severe symptoms and may require prompt medical intervention.

Fungal Infections: Though less common, certain fungal infections can cause pleuritis, particularly in individuals with weakened immune systems or those living in areas where specific fungi are endemic.

Autoimmune Disorders: Conditions like lupus and rheumatoid arthritis can cause pleural inflammation as part of the systemic disease process. In these cases, pleurisy may be recurrent or chronic.

Pulmonary Embolism: Blood clots that travel to the lungs can cause inflammation of the pleura, along with other serious symptoms. This is a medical emergency requiring immediate attention.

Chest Trauma: Injuries to the chest, including rib fractures or blunt force trauma, can damage the pleural membranes and lead to inflammation.

Certain Medications: Some drugs can cause drug-induced pleurisy as a side effect, though this is relatively rare.

Cancer: Lung cancer, mesothelioma, or cancers that have spread to the chest can cause pleural inflammation or pleural effusion.

Prevention Strategies

While not all cases of pleurisy can be prevented, certain measures can reduce your risk of developing this painful condition:

Practice Good Hygiene: Since many cases stem from viral or bacterial infections, frequent handwashing, avoiding close contact with sick individuals, and maintaining good respiratory hygiene can help prevent infections that lead to pleurisy.

Get Vaccinated: Stay up to date with recommended vaccinations, including the annual flu vaccine and pneumonia vaccine if recommended by your healthcare provider. These vaccines can prevent infections that commonly cause pleurisy.

Seek Prompt Treatment for Respiratory Infections: Don’t ignore symptoms of respiratory infections. Early treatment of pneumonia, bronchitis, or other lung infections can prevent complications like pleurisy.

Manage Chronic Conditions: If you have autoimmune diseases or other chronic conditions that increase pleurisy risk, work closely with your healthcare provider to keep them well-controlled.

Avoid Smoking: Smoking damages lung tissue and increases susceptibility to respiratory infections. Quitting smoking significantly reduces your risk of developing pleurisy and other respiratory complications.

Protect Against Chest Injuries: Wear appropriate protective equipment during sports or activities with risk of chest trauma. Use seatbelts while driving to prevent chest injuries in accidents.

Maintain Overall Health: A strong immune system can better fight off infections. Eat a balanced diet, exercise regularly, get adequate sleep, and manage stress to support your body’s natural defenses.

Frequently Asked Questions

How long does pleurisy last?

The duration of pleurisy depends on its underlying cause. Viral pleurisy typically resolves within a few days to two weeks, while bacterial cases may take longer and require medical treatment. Pleurisy associated with chronic conditions may be recurrent or persistent.

Is pleurisy contagious?

Pleurisy itself is not contagious, but the underlying infections that cause it (such as viral or bacterial infections) can be transmitted to others. If your pleurisy is due to an infectious cause, you may spread that infection to others through respiratory droplets.

Can pleurisy go away on its own?

Mild cases of viral pleurisy may resolve without specific treatment, but medical evaluation is important to determine the cause and severity. Bacterial pleurisy typically requires medical intervention. You should never ignore pleurisy symptoms, as some causes can be serious and require prompt treatment.

What’s the difference between pleurisy and pneumonia?

Pneumonia is an infection of the lung tissue itself, while pleurisy is inflammation of the pleural membranes surrounding the lungs. However, pneumonia can cause pleurisy as a complication. Pleurisy is characterized by sharp, breathing-related chest pain, while pneumonia more commonly presents with productive cough, fever, and general respiratory symptoms.

When should I see a doctor for chest pain?

You should seek immediate medical attention if you experience severe chest pain, especially if accompanied by difficulty breathing, high fever, rapid heart rate, bluish discoloration of lips or nails, or if the pain is sudden and severe. Any unexplained chest pain warrants medical evaluation to rule out serious conditions.

Can pleurisy cause permanent damage?

Most cases of pleurisy resolve without long-term complications when properly treated. However, if left untreated or in severe cases, complications such as pleural effusion, lung scarring, or chronic pain may develop. This is why prompt medical evaluation and appropriate management are important.

Is the pain from pleurisy constant or does it come and go?

Pleuritic chest pain typically comes and goes in relation to breathing. It intensifies with deep breaths, coughs, or sneezes, and may lessen when holding your breath or breathing shallowly. Some patients experience more constant discomfort with sharp exacerbations during respiratory movements.

Can exercise make pleurisy worse?

Yes, physical activity typically worsens pleurisy symptoms because exercise increases breathing rate and depth, which aggravates the inflamed pleural membranes. Rest is generally recommended during the acute phase of pleurisy, with gradual return to activity as symptoms improve and under medical guidance.
