Home remedies for otitis externa

Otitis externa, also called swimmer's ear, is irritation or infection of the skin lining the outer ear canal. Water left in the canal, scratching, earbuds or cotton buds can damage this delicate skin. Pain may worsen when the outer ear is pulled or touched, and there may be itching, swelling or discharge. Earache and hearing change can have other causes, so symptoms alone cannot confirm the diagnosis.

Keep water, shampoo and hair products out of the affected ear; use a shower cap or gently shield the opening without pushing anything inside. Do not swim until symptoms have settled and a clinician advises it is safe. Do not scratch, probe, or place oil, alcohol, peroxide or leftover ear drops in the canal. Pain relief may be suitable for some people, but check the label and ask a pharmacist if you have other conditions or take regular medicines. Prescribed drops may be needed after examination.

Arrange a GP consultation if pain, swelling or discharge is present, because the ear canal may need cleaning and targeted drops. Seek urgent help for severe pain, spreading redness, fever, facial weakness, marked dizziness or sudden hearing loss. People with diabetes or a weakened immune system should seek advice promptly rather than relying on home care.

Ask whether the eardrum can be seen safely, which drops are appropriate, how to keep the ear dry, and when you can return to swimming or using earbuds.
