Does any of this apply?
Book an appointment
Book a routine appointment if mild earache lasts longer than two to three days, keeps returning, or comes with gradual hearing changes.
Persistent drainage, ringing, or pain when chewing also needs assessment.
Every sign above is quoted from the sofidex article on Earache. If you are not sure, err upward — it is always reasonable to be checked.
