I am a Registered Medical Assistant and used to work for an ear specialist. He showed us a video on ear/ER cases. The #1 most frequent ear damages are caused by using Q-Tips. Several were men and women who were in their bathroom with a Q-tip in their ear, possibly, not too far in. Then one of their kids comes RUNNING into the bathroom slamming the arm and q-tip DEEP into the ear canal and puncturing the ear drum.
Bobby Pins ARE JUST AS DANGEROUS, POSSIBLY WORSE BECAUSE THEY ARE METAL!!! I can see brain injuries from a bobby pin being SLAMMED DEEP INTO THE EAR DRUM and possibly on into the brain.
The old saying: "DON'T STICK ANYTHING INTO YOUR EARS LARGER THAN YOUR ELBOW!!!"
