Ear popping could be due to a couple reasons. It could be built-up earwax causing a sensation of clogged ears which may pop when you move your jaw. Another possibility is excessive mucus in the eustachian tube, causing a popping sensation and discomfort. We can perform an ear exam by looking inside your ears to determine the cause. If your ears are free of earwax, then we will refer you to an ENT to determine if your eustachian tubes are the culprit.
