The short answer
Earache is common and usually not serious. The pattern that deserves follow-up is one-sided ear pain with a normal-looking ear, especially with a sore throat, hoarseness, swallowing trouble or a neck lump.
The NHS says most earaches get better on their own, but to get medical help if symptoms do not improve within two to three days.
NCI lists ear pain, or pain and ringing in the ears, among the symptoms of cancers of the throat and voice box.
Ear pain that stays on one side while the ear itself looks normal is the pattern that most often prompts an ENT referral.
Swelling or redness behind the ear, a facial droop, or a very high temperature with shivering needs urgent care.

The full explanation.
Ear pain that does not start in the ear
The ear shares nerve supply with the throat, the tongue base, the voice box and the teeth. So a problem in any of those places can be felt as earache. Doctors call this referred pain.
That is the single most useful idea on this page. If your ear hurts but the ear looks healthy when examined, the cause is probably somewhere else nearby.
Most of the time that somewhere else is a tooth, a jaw joint or a throat infection. Occasionally it is something a specialist needs to see.
When an ear infection spreads
The mastoid bone sits just behind the ear. An infection can reach it. MedlinePlus describes mastoiditis as redness behind the ear, swelling that can push the ear outward, fever, headache and hearing loss.
Call 911 or go to an emergency department if you have:
- swelling or redness behind the ear, or an ear that looks pushed forward, with severe headache or drowsiness.
- a droop or weakness on one side of the face.
- a very high temperature with shivering, fast breathing, confusion, or blue, grey or blotchy skin.
That last group is the NHS list of sepsis symptoms in adults, and it applies to any infection.
How long earache should last
The NHS says most earaches get better on their own, and to get medical help if symptoms do not improve within two to three days.
Ask for an urgent appointment sooner if earache comes with:
- a very high temperature, or feeling hot, cold or shivery.
- swelling around the ear.
- fluid leaking from the ear.
- hearing loss or a change in hearing.
- feeling generally unwell.
The usual causes
Ordinary explanations cover nearly all earache:
- middle ear infection, especially in children.
- outer ear infection, common after swimming.
- earwax buildup.
- jaw joint problems and teeth grinding.
- a dental abscess or teething.
- throat infection, tonsillitis or quinsy.
- sinus problems, or pressure changes from flying.
The pattern that points to head and neck cancer
NCI's head and neck cancer information lists ear symptoms directly. For cancers of the throat, it names pain or ringing in the ears and trouble hearing. For cancer of the voice box, it names ear pain alongside trouble breathing or speaking and pain on swallowing.
So the concerning picture is not earache by itself. It is earache that:
- stays on one side and does not settle.
- persists while the ear itself looks normal.
- arrives with a sore throat, hoarseness or trouble swallowing that lasts.
- comes with a lump in the neck.
The NHS advises seeing a doctor for a hoarse voice that does not go away, difficulty swallowing, or a lump in your mouth, neck or throat. Risk is higher for people who smoke and drink heavily, and HPV infection raises the risk of some throat cancers.
Why an ENT referral gets offered
A clinician will look in the ear, the mouth and the throat, and feel the neck. If the ear is healthy and the pain persists, that is when ENT enters the picture.
An ENT specialist can pass a thin flexible camera through the nose to see the tongue base, tonsils and voice box. Areas a torch cannot reach. If something looks abnormal, the next steps are usually imaging and a biopsy.
Accepting that referral is not a sign anyone thinks you have cancer. It is how the question gets closed.
Describing the pain accurately
Say which ear, how long, and whether the pain is constant or comes in waves. Mention hearing changes, discharge, dizziness, and anything that makes it worse, such as chewing or swallowing.
Add your smoking and alcohol history without editing it, and flag any throat symptom that has lasted three weeks or more. Head and Neck Cancer covers what those specialists look for.

Common questions
Does ear pain mean I have cancer?
Almost always not. Ear infections, earwax, jaw joint problems, dental problems, throat infections and sinus problems cause the vast majority of earache. Cancer is one possible cause in certain patterns, but a clinician needs to evaluate the full picture.
How long should I wait?
The NHS advises getting medical help if earache does not improve within two to three days, and sooner if you have a high temperature, swelling around the ear, fluid leaking from the ear, or a change in hearing.
What should I bring to the visit?
Bring which ear hurts and for how long, whether hearing has changed, any throat pain, voice change or swallowing trouble, any neck lumps, your dental history, and your smoking and alcohol history.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
