Ear Canal Problems (Swimmer's Ear)
Swimmer's ear (otitis externa) is a painful inflammation and infection of the Reference ear canal Opens New Window Reference Opens New Window. It occurs when the protective film that covers the ear canal (lipid layer) is removed. This causes the ear canal to look red and swollen. The ear canal may be narrower than normal and is tender when the outside of the ear is gently pulled up and back.
