Garlic Oil for Ear pain:

"You can also make garlic oil. Fill a small sterilized jar (like a baby food jar) to the top with cold-pressed extra-virgin olive oil (or mullein oil, available at health food stores). Coarsely chop two or three cloves of fresh garlic, and drop them in. Cap it tightly, and store in a cool, dry place for a week or so. Then remove the garlic pieces. You can add 5-10 drops of Grapefruit Seed Extract to the oil to give it a longer shelf life. (GSE is also available at health food stores. I like Nutribiotic brand.)

To treat earache, drop a few drops of the warmed oil into the ear canal, and cover with a small ball of clean cotton. Apply warm compresses to ease the pain. Treat one or two times a day and before bedtime.
