Blocked ears can be caused by various factors, including:
-
Eustachian tube dysfunction: This occurs when the Eustachian tube, which connects the middle ear to the back of the throat, doesnt open and close properly. When the Eustachian tube doesnt open and close properly, it can cause a clogged-up feeling. This can happen due to swelling or fluid, which can be caused by allergies, sinus or ear infections, or other respiratory viruses.
-
Earwax blockage: Earwax blockage occurs when earwax builds up in your ear or becomes too hard to wash away naturally. Earwax is a helpful and natural part of your bodys defenses, but if it builds up, it can block your ear canal and cause a clogged feeling. Earwax blockages often happen when people try to get earwax out on their own by using cotton swabs or other items in their ears.
-
Sinus drainage, colds, or allergies: These can cause a clogged ear due to Eustachian tube blockage. Fluid and mucus can become trapped in the middle ear and clog the ear instead of flowing down the throat. This blockage usually accompanies an infection, such as the common cold, influenza, or sinusitis. Allergic rhinitis can also cause a blockage in the Eustachian tube.
-
High altitude: Changes in air pressure can cause a clogged ear due to Eustachian tube blockage. This is why people often experience clogged ears when riding in an airplane. Swallowing, chewing gum, and pinching the nose and gently blowing can help to get the Eustachian tube to open.
-
Other factors: Other factors that can cause a clogged ear include impacted earwax, problems with pressure equalization, and sudden onset of muffled hearing in one ear, which may signal an urgent problem requiring prompt treatment to prevent or reduce possible hearing loss.
Its important to identify the cause of a clogged ear to determine the best way to treat the clog and prevent future problems. If youre experiencing a clogged ear, you should see your primary care provider and ask for a referral for a hearing evaluation.
