Sid, show your folks my post to you. First of all, you should go to the doc to make sure there is no infection. With Swimmer's Ear several things can happen. I would get ear infections from swimmer's ear a LOT until I was about 13 or 14 ... and occasionally even again after that. It eased up though when my doctors finally realized what the problem was. So,
1. See the doctor ... have him/her verify there is no infection
2. For future swimming, hair washing, etc, use earplugs OR use cotton balls covered with vaseline to keep water out of your ears
3. Keep in mind that if your ears don't drain the water well, or if you are prone to infection, that water (or other fluid build-up) is a great source for reproduction of bacteria that can cause infection.
Hopefully, they'll take an adult's word for the problem and get you in for a check. If not, how much of a problem is it to get services from a public health facility?
