Chest Catching Sensation When Breathing Deeply: Causes & Solutions

A "catch" or sharp pain on deep inspiration has several causes, ranging from benign to life-threatening.

Musculoskeletal (Common)

• Intercostal muscle strain: Coughing, exercise, twisting. Tender to palpation, reproducible.
• Costochondritis: Costochondral junction inflammation. Reproducible tenderness at sternal edges.
• Rib fracture/bruise: Trauma history; focal pain.

Pleuropulmonary

• Pleuritis (pleurisy): Sharp, breathing-worsened pain. Causes: viral, pneumonia, PE, autoimmune.
• Pneumothorax: Sudden unilateral pain + dyspnea. Tall thin males, trauma, COPD. Emergency.
• Pneumonia: Fever, cough, focal findings.

Cardiac

• Pericarditis: Sharp, pleuritic, better leaning forward. Diffuse ST elevation on ECG.
• Angina/MI: Pressure, exertional; but can be atypical.

GI

• Hiatal hernia/GERD: Heartburn, regurgitation, worse lying down.

Red Flags → Immediate ER
