You can also put some drops mullein or olive oil with garlic in the infected ear. You can buy this in a health food store already done or make your own.
Put some olive oil in a glass and put it in a pot of hot water (not on the stove or boiling) and cut up a couple of cloves of garlic and let it sit until it picks up the aroma. Then put 3-4 drops in the infected ear 2 or 3 times a day.
