A sharp or dull chest pain that worsens when lying down, especially when breathing, may be due to pericarditis, an inflammation of the sac surrounding your heart.
Pericarditis and Pain
Pericarditis can cause chest pain that feels:
- Sharp and stabbing: This pain may come on suddenly.
- Dull ache: Some people experience a less intense, but still persistent, ache.
The pain associated with pericarditis often becomes more noticeable or intense when you:
- Lie down
- Breathe deeply
This is because the position change and expansion of the chest can irritate the inflamed pericardium, the sac around the heart.
Other Possible Causes of Chest Pain
While pericarditis is a possible explanation, other conditions can also cause chest pain when lying down. These include:
- Musculoskeletal issues: Pain from muscles, ribs, or cartilage in the chest wall.
- Lung conditions: Such as pleurisy or pneumonia.
- Gastrointestinal problems: Acid reflux can sometimes cause chest pain.
When to See a Doctor
If you experience chest pain that worsens when lying down, especially with difficulty breathing or other symptoms, consult a healthcare professional promptly to determine the underlying cause and receive appropriate treatment.
