A. Feeling as though our ears are congested can be uncomfortable and a little startling, particularly if it makes it difficult for us to hear well. But figuring out why is not always simple. Impacted earwax, a sticky accumulation of the normally normal secretions that lubricate the ear canal, is a frequent cause. Although you might be tempted to try using a cotton swab to remove it, this strategy can backfire and push wax deeper. Instead, use over-the-counter earwax removal solutions to loosen and soften waxy accumulation.
Swollen or obstructed eustachian tubes, which link the middle ear to the back of the throat, can also cause clogged ears. In addition to allergies, sinus or ear infections, or other respiratory viruses (including COVID-19), this can occur for brief periods of time during air travel. A sudden start of muffled hearing in one ear could indicate a serious issue that has to be treated right away in order to prevent or lessen potential hearing loss. If the issue persists for more than a day or two, consult your physician.
