It is a good thing that you are getting your hearing checked out at school. If something is wrong, you can fix it right away before anything gets worse. Good luck! You are in my thoughts and prayers and I hope that all you have to do is get them cleaned out. Also, next time listen to your doctor. I know dances are fun, but I also know that there is a lot of loud music. Don't go to the dances with extremely loud music. Sure you will be missing out on a lot of fun, but do you really want to miss out on hearing for the rest of your life! Like I said, you are in my thoughts and prayers and I hope that everything goes alright with you.

P.S. Don't get discoraged if something does go wrong. If people are talking to you just say something like, "excuse me, I have a little trouble with hearing, could you please speak up." That way, they know that you are listening.
