π Quick Summary
An ear infection can affect the middle ear behind the eardrum or the outer ear canal.
Middle ear infections are especially common in children and often develop after a cold.
Symptoms may include ear pain, fever, irritability, reduced hearing or fluid coming from the ear.
Many mild middle ear infections improve without antibiotics, but worsening symptoms, ear discharge or significant hearing changes should be assessed.
π Not every earache is an infection, and not every ear infection needs antibiotics.
1οΈβ£ What is an ear infection?
The two common types are:
Middle ear infection (acute otitis media) — infection develops behind the eardrum.
Outer ear infection (otitis externa or swimmer's ear) — infection affects the ear canal.
Fluid can also remain behind the eardrum after an infection. This is called otitis media with effusion and does not necessarily mean an active infection is still present.
2οΈβ£ Why does it happen?
For a middle ear infection, a cold or other respiratory infection can make the Eustachian tube — the small passage connecting the middle ear to the back of the nose and throat — swollen or blocked.
Fluid then becomes trapped behind the eardrum, where viruses or bacteria may cause infection. Children are particularly prone because their Eustachian tubes are smaller and more easily blocked.
Outer ear infections develop differently. Moisture, scratching, cotton buds or damage to the ear canal can weaken the skin and make infection easier.
π Middle and outer ear infections may both cause ear pain, but the location and treatment are different.
3οΈβ£ What symptoms can it cause?
Symptoms may include:
• ear pain or pressure
• fever
• reduced or muffled hearing
• fluid or pus coming from the ear
• feeling of fullness inside the ear
Young children may instead become irritable, sleep poorly, cry more than usual or repeatedly pull at the affected ear.
Pain when pulling or touching the outer ear is more suggestive of an outer ear infection.
4οΈβ£ What can help?
Pain relief and fluids may be enough while some mild middle ear infections settle naturally.
Treatment may include:
• appropriate pain relief such as acetaminophen/paracetamol or ibuprofen when suitable
• antibiotic treatment for certain bacterial infections
• antibiotic ear drops for some outer ear infections
• keeping the ear dry when advised
Many mild middle ear infections improve without antibiotics, so a healthcare professional may sometimes recommend watchful waiting for 2–3 days depending on age, symptoms and severity.
Do not put cotton buds or other objects inside the ear, and do not use prescription ear drops belonging to another person.
π Antibiotics are useful when they are needed — but they do not improve every ear infection.
5οΈβ£ Possible complications
Most ear infections settle without lasting problems.
Less commonly, complications can include:
• temporary hearing loss from fluid behind the eardrum
• a perforated eardrum
• repeated ear infections
• infection spreading to the bone behind the ear (mastoiditis)
Persistent hearing problems in young children may affect speech or language development and should be assessed.
6οΈβ£ π©Ί When should you seek medical help? π¨
Arrange medical assessment if:
• symptoms are worsening or last more than 2–3 days
• fluid, pus or blood comes from the ear
• hearing becomes reduced
• pain is severe or repeatedly returns
• fever is high or the person appears significantly unwell
A baby younger than 3 months with a temperature of 38°C (100.4°F) or higher needs prompt medical assessment.
Seek urgent medical help if there is:
• swelling, redness or severe tenderness behind the ear
• the ear begins sticking outward because of swelling behind it
• facial weakness
• severe headache, neck stiffness, confusion or marked drowsiness
π These symptoms may suggest that infection has spread beyond the middle ear and should not be watched at home.
π’ Important Message
Ear infections are common, particularly in children, and many improve without complications.
The important things are how unwell the person is, whether symptoms are improving and whether hearing, discharge or swelling develops.
π Treat the pain, watch the pattern and seek assessment when symptoms are severe, persistent or worsening.
FAQ
• Does every ear infection need antibiotics?
No. Many mild middle ear infections improve without antibiotics.
• Can a cold cause an ear infection?
Yes. A cold can block the Eustachian tube and allow fluid to collect behind the eardrum.
• Is pulling the ear always a sign of infection in a child?
No. Children may pull their ears for several reasons, so other symptoms and examination of the eardrum matter.
• Can an ear infection affect hearing?
Yes. Fluid behind the eardrum can temporarily make hearing muffled.
• Can swimming cause an ear infection?
Swimming is particularly associated with outer ear infection (swimmer's ear) rather than the usual middle ear infection.
π§ Why We Delay
Ear pain may be blamed on teething, water entering the ear or an ordinary cold, especially when a child cannot explain exactly what hurts.
Many mild infections do improve, but persistent pain, discharge or hearing changes should not simply be ignored because the fever has gone.
π If the pattern is getting worse rather than better, that is the point to get the ear checked.
