Chiropractic is very effective for ear infections. The direct effect is to open the Eustachian tube from the inside so it can drain out relieving the pressure caused by the infection. This is done by adjusting the upper neck and sometimes the jaw. Another effect is to improve the overall function of the immune system so that the body can better fight off the infection. This is done by removing any subluxations of the spine, a specialty performed exclusively by doctors of chiropractic.
