What Causes Blocked Ears?
Air travel, common colds, sinus infections or impacted earwax –each is an example of what causes blocked ears. When we have colds, or when we travel by air, we feel some kind of fullness in our ears. It usually happens when the air pressure on both sides of the eardrum is not equal. Nasal allergies and sinus infections, for instance, cause blocked ears because the membranes that line the Eustachian tube are similar to continuous with nasal membranes. The Eustachian or auditory tube is membrane-lined and connects the back of the nose with the middle ear. Thus, when you have colds of sorts, you feel fullness in your ears because the swollen membranes block the Eustachian tube’s opening. Moreover, this imbalance of air pressure in the ears drums and a blocked Eustachian tube can be one of the reasons why a person experiences tinnitus or ringing in the ears. Swallowing and yawning are the practical ways of unblocking your ears. If they do not work, however, you can pinch your nostrils shut
