My girlfriend had an ear infection too, her whole face hurt from the pain and she was deaf in that ear, she went the doctors and got anti-inflammitry tablets and recovered and now she has both ears 100%. Hope you can fix it, it's not nice.
My girlfriend's got labyrinthitis. It means she goes dizzy and falls over sometimes.
Bizarrely enough, three of the teachers she works with have got it too. I would love to be a fly on the wall at their school one day, watching all these teachers just randomly keeling over, I bet it's a riot!
