Vincent van Gogh had an answer
inner or outter? because an inner infection needs antibiotic an outter one usually clears up with a few days of have white vinegar and half peroxide...a couple times a day...see if that helps.
they all hurt. Outer will hurt by your ear inner more when you swallow. And if you have a temp, usually inner and you need a Dr.
Not that I know of. My mother used to put sweet oil in my ears when I would get an infection. It oils the ear drum so that the stretching (which is what causes the pain) doesn't hurt as bad.
It's basically olive oil. You can find it anywhere, but if you buy it at a pharmacy, it comes in a bottle with a dropper for ear use.
It's called "Sweet Oil" when you get it at a pharmacy.
