A previously healthy 15-year-old girl presents with right-sided chest pain that began a few hours earlier during Spanish class. The pain is nonradiating; it is alleviated by leaning forward and exacerbated by sitting still. Shortly after its onset, the patient had taken acetaminophen, which provided temporary relief. However, when she returned home from school, the pain resumed. She denies fever, shortness of breath, nausea, vomiting, and cough.
