Which position-related pattern is characteristic of pericarditis pain?

• A. Pain worsens with rest
• B. Pain improves with sitting forward
• C. Pain is unaffected by position
• D. Pain improves when lying flat

Answer: (B)

Pain from pericarditis typically improves when you sit up and lean forward. This position changes the way the inflamed pericardial surfaces move and reduces the friction and traction they experience during chest and diaphragmatic movements, which eases the irritation and lowers the pain. When you lie flat, the heart is more compressed and the pericardial irritation can be stretched more with breathing and gravity, often making the pain worse. This positional relief—pain easing with sitting forward—is a classic feature that helps distinguish pericarditis from other chest pain patterns.
