CHART CLUE

Recurrent, sharp, breathing-linked chest pain that eases when Stina leans forward — with a scratchy friction rub and a small pericardial effusion on echo — is not anxiety and not a heart attack. It is pericarditis: FMF serositis reaching the lining around the heart, the same fire that inflames the abdomen (peritonitis) and the chest wall (pleuritis).

The Story

From Stina’s chart:

Compare Stina’s uninfected appendix to an infected appendix.
