I am not a Dr. But I used to have this trouble alot due to taking showers and my dr told me to use white vinegar and rubbing alchohol and mix it up and squirt it in my ear with a syringe but don't put the syringe in your ear real deep as it is dark in your ear and you sort of get a type of fungus in it and it does not dry properly. You can go out and buy the stuff for swimmers ear he said which is over the counter but he said it has about the same thing in it and this is cheaper, it might burn a little bit plus I used to swim a lot too.
Good luck!

Alright thanks I will try that and see what happens
