What are the causes of ear clogs?

* Earwax. Earwax is a natural substance that helps to protect the ear canal from infection. However, too much earwax can cause a blockage, which can lead to hearing loss, pain, and tinnitus (ringing in the ears).

* Foreign objects. Small objects, such as cotton swabs, paper clips, and insects, can become lodged in the ear canal and cause a blockage.

* Infections. Infections of the ear, such as otitis media (middle ear infection) and otitis externa (outer ear infection), can cause swelling and fluid buildup, which can lead to a blockage.

* Allergies. Allergies can cause inflammation and swelling in the ear canal, which can lead to a blockage.

* Sinusitis. Sinusitis is an infection of the sinuses, which are located near the ears. Sinusitis can cause congestion and fluid buildup in the ears, which can lead to a blockage.

* Barotrauma. Barotrauma is a condition that occurs when there is a sudden change in air pressure, such as during air travel or scuba diving. Barotrauma can cause the eardrums to become sucked in or pushed out, which can lead to a blockage.

* Ear canal tumors. Ear canal tumors are rare, but they can cause a blockage and lead to hearing loss.
