What causes outer ear infections?
Outer ear infections are also known as swimmer's ear, since they tend to develop after swimming, showering, or other activities that cause the ears to become waterlogged. The soggy skin in the ear canal provides an ideal environment for bacteria and fungi to grow, which can then lead to an infection. Less commonly, outer ear infections may be caused by factors that damage the ear canal, such as cleaning with cotton buds, an underlying skin condition, or a build-up of hair products or soap.
