What condition is characterized by chest pain that worsens with chest movement or breathing?

• A. Pleurisy
• B. Pneumothorax
• C. Heart attack
• D. Interstitial lung disease

Answer: (A)

Pleurisy, also known as pleuritis, is characterized by sharp chest pain that worsens with breathing, coughing, or any movement of the chest wall. This condition occurs when the pleura, the two thin layers of tissue separating the lungs from the chest wall, become inflamed. The inflammation causes friction between the pleural layers during respiration, leading to localized pain that can intensify with deep breaths or changes in position.

Patients typically describe the pain as pleuritic if it is sharp and worsens when they breathe deeply, cough, or move. This symptom helps differentiate pleurisy from other possible causes of chest pain, which may not provoke such pain with breathing or movement in the same way.
