Have you ever experienced a feeling of fullness or discomfort in your ear? You may have heard a popping or crackling sound when you swallow or yawn. These symptoms could indicate Eustachian Tube Dysfunction (ETD).
The Eustachian tube is a small passageway that connects the middle ear to the back of the throat. Its primary function is to equalize the pressure in the middle ear with the pressure outside the body.
However, when the Eustachian tube becomes blocked or doesn't open properly, it can result in symptoms that may include ear pain, muffled hearing, and even dizziness.
