In a Peds ER, this kind of thing is our bread-&-butter.
Also love any complaint that has since stopped before bringing them in: baby wouldn't stop crying (as the baby looks up and smiles at me), nose bleed, headache, anxiety attacks in pre-teen girls.
Most ridiculous ever in my years, had a 2-yr old come by squad on an for "possible seizure activity". After arrival, mom pulls out a bottle of Vicodin, pops one and starts going on and on about her horrible toothache, then climbs into the bed herself. Meanwhile, the kid is playing and tearing the room apart. At one point before she passed out, the kid threw himself on the floor with a typical 2-yr-old-tantrum, mom points and says "There! He's doing it again,see?! A seizure".
We transferred mom across the street to the neighboring adult ER, after she insisted on checking herself in for her toothache.
A few hrs later get another squad call that sounded a lot like the morning one......yup, they were back! Had another "seizure". Mom crawled into bed and passed out, must have just wanted a babysitter so she could take pills and sleep. Social Work helped us with that one. =) nothing like wise use of resources!
