Be seen today
Seek urgent same-day medical assessment if you or your child has redness, pain, tenderness, or swelling behind an ear, especially if the ear is being pushed outward.
This is particularly important when there is fever, ear discharge, worsening ear pain, or a recent middle ear infection.
During treatment, tell the hospital team promptly if pain, fever, swelling, headache, hearing, or alertness worsens.
Routine follow-up is still important after the urgent infection has settled.

Does any of this apply?
Book an appointment
Arrange the recommended review for wound checks, hearing tests, or monitoring of chronic ear disease.
Seek a non-emergency appointment if ear discharge, reduced hearing, or discomfort continues or returns.
