Just Curious...

I'm wondering how many swimmers out there treat outer ear infections themselves (without a Dr. visit). I haven't gone to the Dr. for an outer ear infection since I was little. When I was swimming in high school and college I would use straight isopropyl alcohol before and after swimming if my ear hurt. It would always clear up in one or two days. I've sworn by that ever since. A couple of years ago, I mentioned that to a pharmacist while picking up a prescription med for my child's ear infection. The pharmacist seemed horrified that I would even think about using straight isopropyl alcohol on my child's ear infection. So I never have. Anyone else out there who has treated a sore ear this way??? I swear I learned this technique from a coach somewhere along the way...
