Im a bit late, and this may have been said, but walmart, and drugstores have a solution that is called/for
SWIM-EAR, that is the name brand, which there are others, what you have I think is swimmers ear. where water gets stuck and wont come out.
The stuff I think is mainly rubbing alcohol, and you lay on your side, put the drops in, wait a couple minutes, it might burn a little, and then turn over and hold a klenex up to your ear, as a lot of liquid will probably come out. I have to do sometimes after I get done swimming,
