Had a 2nd grader come in with a sore throat, checked her temp (normal), looked at her throat with a light, asked her questions (like, how long has it hurt, etc.) she then said.... "it feels like a toenail is stuck in my throat"...... so I had to ask....... "do you chew on your toenails?" She then looked at me with a sheepish grin & said "yes" I then educated her on the infection risk on that, lol...... 2 days later she came back in concerned "because my boo boo is green & it spreads in the toilet" I told her maybe it was because she was chewing on her toenails, lol
