What to do if…
you have sudden severe ear pain with fever and swelling behind the ear

Short answer

Go to an Emergency Room now (or call 911 if you’re very sick or deteriorating). Fever plus swelling behind the ear can be a sign of mastoiditis or another serious infection that needs urgent treatment.

Do not do these things

  • Do not wait for a routine appointment if you have fever and swelling behind the ear.
  • Do not put anything into the ear canal (no cotton swabs, probing, or “draining”).
  • Do not take leftover antibiotics or someone else’s antibiotics.
  • Do not use ear drops unless a clinician has told you to (some drops aren’t safe if the eardrum may be perforated).
  • Do not exceed the labeled dose of acetaminophen (paracetamol) or ibuprofen, and avoid doubling up on products that both contain acetaminophen.

What to do now

  1. Go to the ER today (now). Tell them clearly at check-in: severe ear pain + fever + swelling behind the ear. If you feel faint, confused, or too dizzy to travel safely, call 911 (or get someone to take you) rather than driving yourself.
  2. Call 911 immediately if any of these are present: trouble breathing, confusion, severe drowsiness, neck stiffness, a severe/worst headache, seizure, a rapidly spreading rash, uncontrolled vomiting, new facial weakness, or rapidly increasing swelling/pain.
  3. Use safe pain/fever relief while you’re getting care.
    • Take acetaminophen or ibuprofen if you can take them, following the package directions.
    • Write down the dose and time you took it so the ER team can safely give additional medication if needed.
  4. Keep the ear protected and don’t irrigate it.
    • If there’s drainage, wipe only the outside with clean tissue/gauze.
    • Avoid getting water in the ear (no swimming; avoid directing shower water into the ear).
  5. Bring the minimum useful information.
    • Photo of any swelling/redness (if visible), your medication list/allergies, and when symptoms started, highest temperature, discharge, hearing change, and any recent ear infection or antibiotics.

What can wait

  • You do not need to decide whether it’s “just an ear infection” versus something else—focus on being evaluated urgently.
  • You do not need to try home remedies, “popping” ears, peroxide, or ear candles.
  • You can sort out insurance/payment questions and follow-up arrangements after you’re medically assessed and stabilized.

Important reassurance

This symptom combination is scary for good reason—but getting urgent evaluation is a straightforward, appropriate step. Many people improve quickly once the correct treatment starts.

Scope note

This is first-steps-only guidance for the next few hours. Diagnosis and treatment depend on an in-person exam and sometimes imaging or specialist input.

Important note

This is general information, not medical advice or a diagnosis. Fever with swelling behind the ear can indicate a serious infection—seek urgent evaluation the same day, and use emergency services if symptoms are severe or worsening.
