Other Causes
Other possible causes of a swollen ear canal include:
– Using a cotton swab may push ear wax or bacteria farther into the ear, which may increase the risk of an ear infection.
– The presence of a foreign object in the ear would lead to an accumulation of bacteria and dirt.
– A small cut or wound in the ear canal would make it easier for bacteria to penetrate the ear canal and lead to an infection. [6]
