Clogged Ear From Cold -

When you have a cold, your Eustachian tube (a small tube that connects your middle ear to the back of your throat) can become blocked due to inflammation and congestion. This blockage can cause your ear to feel clogged, muffled, or even painful.

When the tube is shut, it creates a vacuum. Fluid can no longer drain, and air cannot enter. The middle ear becomes a sealed chamber, often trapping mucus. The eardrum, sucked inward by the vacuum, becomes tense and immobile. The result? Muffled sound and a feeling of fullness. clogged ear from cold
