When I was swimming competitively I would get water in my ear occasionally and it won't come out for a day, so I would try different things. I am no doctor, but I hate going to them, so I did all kinds of crazy things. The least crazy was to pick up these drops from the store for swimmers ear, alcohol drops also worked.
Now don't laugh because it worked for me, this is the craziest and funniest....If I had water in my right ear, I would tilt my head down to the right side and then jump on my right foot up a set of stairs a couple of times until the water popped.
Silly huh, but man it worked for me. I know someone is going to call me stupid and tell me I shouldn't give crazy advice, so here is my disclaimer...I am not telling you to try this. I am just sharing with you what I did to get water out of my ear.
