Today’s（September 25）Time magazine reports that:
Federal Reserve Chair Janet Yellen is feeling "fine" following a brief medical scare during an evening speech. Yellen was speaking at the University of Massachusetts at Amherst when she abruptly stopped her address due to dehydration, according to a spokesperson.
I don’t think I’ve ever heard of the word, ‘medical scare.’ I don’t find it in English dictionaries at hand, nor its definition on google search.
Is it a physical symptom something like anemia or dizzy feeling? Is it a medical term? Is it a relatively new word? Apparently it should be different from ‘medical threat.’
