otitis media vs. otitis externa

Ann-Krestene just posted about how hydrogen peroxide quickly cured her daughter's ear infection. I get excited about any way to avoid using antibiodics if possible. I work in an emergency room and MRSA is on the rise due to widespread antibiodic and antibacterial-gel use so I'm really conscious - okay, downright paranoid - about it. And as Ann-K says, hydrogen peroxide is $1 a bottle, can't beat that with a stick.
