Frequently asked questions
How is it different from a middle ear infection?
Swimmer's ear affects the outer canal and hurts when you tug the ear, while a middle ear infection sits behind the eardrum and often follows a cold.
Can I prevent it?
Dry your ears gently after swimming, avoid cotton buds, and consider well-fitting ear plugs if you swim often.
