Reasons for Plugged Ears
Many people experienced plugged ears when they have a cold or sinus infection. Plugged ears also occur with changes in altitude, on a driving trip into the mountains, or when airplanes take off. They are caused because pressure builds up in the ear canal, and it needs to be relieved. For the most part, these instances may be uncomfortable, but they are minor and temporary. However, if the plugged ears persist, there may be other causes.

Ear Wax
-
Wax buildup in the ear canal can cause plugged-up ears. Ear wax is necessary to keep things like dust and bugs out of the ear, but excess wax impairs hearing and, if not cleared up, leads to pain, infections and eardrum damage. This condition can be treated with over-the-counter ear wax removers. If wax continues to plug the ears, consult a doctor to rule out anything more serious.
Eustachian Catarrh
-
The eustachian tubes bond the middle ear to the back of the nose, controlling air flow and equalizing the pressure. Eustachian catarrh causes plugged ears because an obstruction has occurred in the middle ear, producing too much pressure in the ear canal. This muffles the sound, and many patients experience ear pain. Decongestants and nasal sprays can clear up mild cases. In severe cases, tubes may be placed in patients' ears to alleviate the pressure.

Otitis Externa
-
Otitis externa is an infection of the outer ear canal. Bacteria and fungus thrive in the ear canal because it is a warm, dark place. Otitis externa is often referred to as swimmer's ear because frequent swimming or showering can cause excess moisture and spur an infection. Cleaning the ears usually helps relieve plugged ears, but medical interventions are necessary if the problem persists after a few days.
High Blood Pressure
-
Ear problems, including plugging, often accompany high blood pressure. When blood pressure is elevated, patients can experience painful throbbing in the ear canal. To relieve plugged ears, patients should be aware of foods that cause a rise in blood pressure and manage their condition according to their doctors' instructions.
Barotitis Media
-
Barotitis media occurs because of damage to the middle ear in the area behind the eardrum. This condition produces plugged ears because an injury leads to pressure buildup. Barotitis media injuries occur in people who sky dive, scuba dive or visit the mountains. In addition to plugged ears, people may feel dizzy and have ear pain. This condition usually clears up on its own in a few hours or a few days. People with persistent ear problems should avoid these activities and air travel.
