Is any of this happening now?
Call 911
Seek urgent same-day care or go to an emergency department for:
Redness, tenderness, or swelling behind the ear
An outer ear that is being pushed forward by swelling
Severe headache, neck stiffness, confusion, or unusual drowsiness
New facial weakness
A seizure
Severe illness, repeated vomiting, or signs of dehydration
Call emergency services if the person is difficult to wake, has trouble breathing, or has a seizure that does not stop promptly.
Routine follow-up, rather than emergency care, is appropriate for lingering mild ear fullness or muffled hearing after the pain and fever have resolved.
And for anyone, someone who:
is bleeding heavily and it will not stop with firm pressure
Other emergency signs, for anyone
Someone who is struggling to breathe, gasping, choking, or cannot get words out
Someone who has chest pain, tightness or pressure lasting more than a few minutes
Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
Someone who is unconscious, or cannot be woken
Someone who has had a seizure that will not stop, or does not wake up afterwards
Someone who has lips or skin that look pale, blue, grey or blotchy
Someone who you believe has taken an overdose or swallowed something poisonous

Is any of this happening?
Be seen today
Seek prompt medical advice if ear pain is severe, symptoms are worsening, or there is no clear improvement after a few days.
An examination is also appropriate for ear discharge, repeated infections, persistent hearing loss, or symptoms in someone with a weakened immune system, a cochlear implant, or significant facial structural differences.
A baby younger than 3 months with a temperature of 38°C or higher needs urgent medical assessment.
Babies younger than 6 months with a possible ear infection should also be assessed promptly.
And for anyone, someone who:
has a fever with a stiff neck, a rash that does not fade under pressure, or severe headache
has a wound that is hot, spreading red, or leaking pus
