Dealing with an earache is just plain misery. I've always used glycerin in my ears and my kid's ears anytime I noticed the first sign of an earache coming on. It works like magic. You can warm the bottle and drop a few drops in your ears or you can use a Q-tip and hold it under hot water and dip it into the glycerin bottle and swirl it in the opening to your ear (that's what I always do) just make sure you don't go down deep into your ear with the Q-tip!
I wrote a whole page about home remedy for earache, look for the button on the left that reads "Home Remedies" and scroll down the list and look for "Earache Home Remedy" and click on the link.
