Does swimmer's ear cause hearing loss?

Swimmer's ear inflames the skin of the outer ear canal. Swelling, debris, or fluid can narrow that passage and reduce the amount of sound reaching the eardrum, creating muffled hearing or a plugged feeling. This change is different from hearing problems arising deeper in the ear, but symptoms can overlap. Pain, itching, tenderness, redness, or drainage may provide useful clues during an examination.

Keep the ear dry and do not insert cotton buds, fingers, or other objects to clear the blockage. Avoid swimming while the canal is sore or draining. Arrange an assessment if hearing remains reduced, because the ear may need gentle cleaning and the correct drops. Do not use drops chosen from a previous episode unless a clinician confirms they are suitable for the current ear.

Seek prompt medical advice for sudden or marked hearing loss, severe pain, fever, dizziness, discharge, or swelling around the ear. Facial weakness, severe headache, or feeling very unwell needs urgent assessment. If you have diabetes, reduced immunity, or a history of ear surgery, contact a clinician early rather than treating persistent hearing change at home.

Ask whether the hearing change is from canal swelling, wax, discharge, or another ear problem; whether the eardrum is intact; which treatment is appropriate; and when hearing should be checked again. Tell them when the change began and whether it affects one or both ears.
