Pleurisy
Pleurisy is a condition where the two thin layers of tissue that separate your lungs from your chest wall become inflamed. This inflammation causes sharp chest pain that typically worsens when you breathe, cough, or sneeze.
Overview
Pleurisy is a condition where the two thin layers of tissue that separate your lungs from your chest wall become inflamed. This inflammation causes sharp chest pain that typically worsens when you breathe, cough, or sneeze.
Understand this condition
The lungs are covered by two thin layers of tissue called pleura that normally slide past each other. When these layers become inflamed, they rub against each other, causing friction and sharp pain. This irritation is felt most strongly when the lungs expand and contract during breathing.
Why it happens
Pleurisy happens when an infection or medical condition triggers inflammation in the pleural membranes. This inflammation disrupts the natural lubrication between the lung and the chest wall. As the condition progresses, fluid may accumulate between the layers, sometimes easing the pain but potentially making breathing harder.
Real-world scenarios
- •This often appears as a sudden stabbing pain when taking a deep breath.
- •People may notice pain that spreads to the shoulders or back.
- •This often appears as localized chest soreness that worsens with a cough.
- •People may notice they are taking shallow breaths to avoid sharp pain.
Common vs serious explanations
- •A lingering cough causing muscle strain in the chest
- •Recent viral respiratory infection that is slowly resolving
- •Minor bruising from a fall or bump to the chest
- •Mild inflammation from a seasonal cold or flu
- A blood clot in the lung blocking blood flow
- A collapsed lung or air trapped in the pleural space
- Severe bacterial pneumonia requiring intravenous antibiotics
- Accumulation of fluid around the lungs (pleural effusion)
