I have had swimmer's ear all week (been too busy to look up how to properly fix it, until today).
After looking up some remedies on here, I recalled the old remedy my mother used to use, which was simple Olive Oil on some kleenex (or cotton ball if that suits your fancy).
I can see how the rubbing alcohol or vinegar might work, given that swimmer's ear is a bacterial infection that causes the inflammation (so no, people, there is *no* actual 'water' that is 'stuck' in your ear).
This site seems to recommend vinegar, though:
National Center for Biotechnology Information (web link does not work when posted here, so best to google them, adding 'swimmer's ear' to your query).
I just tried my left ear with the Olive Oil and it worked like a charm. Within about 5mins it seemed to want to clog up again, so I took a Q-tip and cleaned it out gently. That seemed to fix things on a much longer level for the time being.
My right ear is currently being difficult, so I may go with the alcohol (or vinegar) in it.
I am thankful that at least I have some oil in my right ear to (hopefully) help soothe the sting.
Cheers and thanks again to everyone for all your help,
