The signs that point to an ear infection
An ear infection usually announces itself through ear pain, drainage, or hearing changes that come on over hours or a few days. The pain is often sharp or dull and constant, and it may get worse when you pull on your earlobe or lie on that side. You might also notice fluid leaking from the ear, a feeling of fullness or pressure inside, or temporary hearing loss in that ear.
Not every ear problem is an infection. Earwax buildup, sudden pressure changes (like from flying), or a scratch in the ear canal can cause similar symptoms. But infections have a particular pattern: they usually follow a cold or sinus infection, they hurt noticeably, and they often come with fever or general illness feeling. If you have these signs together, an infection is likely.
Children with ear infections often tug at their ears, cry more than usual, or have trouble sleeping. They may run a fever or seem fussy without an obvious reason. Babies cannot tell you their ear hurts, so unexplained crying, fever, or drainage from the ear is worth taking seriously.
Key Takeaways
- Ear pain that comes on quickly, especially after a cold, combined with fever or drainage suggests an infection rather than another ear problem.
- Fluid draining from the ear, hearing loss in one ear, or a feeling of fullness are common signs that warrant a doctor's visit.
- Children and babies show ear infections differently—tugging at the ear, unexplained fever, or fussiness can be the main clue.
- A doctor can see inside your ear with an otoscope to confirm whether fluid, redness, or pus is present.
When to see a doctor about ear pain
Ear pain that lasts more than a few hours or gets worse deserves a doctor's visit. You do not need to wait for fever or drainage—pain alone is enough reason to be checked. A primary care doctor or urgent care clinic can look inside your ear and tell you what is happening.
See a doctor right away if you have severe pain, fever above 103°F, drainage that looks like pus, hearing loss that does not improve, or swelling behind the ear. These signs can mean the infection is spreading or the eardrum has ruptured. Swelling behind the ear is particularly important—it suggests the infection has moved into the bone.
If you have had multiple ear infections in the past year, mention that when you call. Some people are prone to them, and your doctor may want to track the pattern or refer you to an ear specialist.
What a doctor sees when examining your ear
A doctor uses a tool called an otoscope—a small handheld light with a magnifying lens—to look inside your ear canal and at your eardrum. Through it, they can see whether the eardrum is red, bulging, or has fluid behind it. These are the signs that confirm an infection.
If there is fluid behind the eardrum but no redness or bulging, the doctor may call it otitis media with effusion—fluid without active infection. This often clears on its own but can cause temporary hearing loss. If the eardrum is red and bulging, that is acute otitis media, the most common type of ear infection, and it usually needs treatment.
The doctor may also use a pneumatic otoscope, which gently puffs air at the eardrum to test whether it moves normally. A eardrum that does not move suggests fluid is trapped behind it. This test takes seconds and helps confirm what the doctor is seeing.
Differences between middle ear and outer ear infections
A middle ear infection (otitis media) happens behind the eardrum and is what most people mean by "ear infection." It causes pain, fever, and sometimes drainage if the eardrum ruptures. It often follows a cold because the tube that drains the middle ear (the Eustachian tube) gets blocked by swelling.
An outer ear infection (otitis externa, or swimmer's ear) happens in the ear canal itself—the tube you can see and feel. It usually causes itching and pain that gets worse when you tug on your earlobe or chew. The canal may look red or swollen, and there is often drainage. Outer ear infections are common in people who swim or get water in their ears regularly.
The two feel different and need different treatment. A middle ear infection usually needs observation or antibiotics. An outer ear infection typically needs antibiotic drops applied directly into the canal. A doctor can tell which one you have by looking inside with the otoscope.
Why fever and recent illness matter
Ear infections almost always follow a viral illness—a cold, flu, or sinus infection. The virus causes swelling in the Eustachian tube, which normally drains fluid from the middle ear. When that tube gets blocked, fluid builds up and bacteria can grow in it, leading to infection.
If you have ear pain and you were sick with a cold or sinus infection in the past week or two, that timing is a strong clue. Fever that comes with the ear pain—especially if it is 101°F or higher—also suggests infection rather than just inflammation from the cold itself.
Some people get ear infections without fever, especially if they are adults or if the infection is in the outer ear. But fever combined with ear pain is one of the clearest signs that bacteria have moved in and treatment may be needed soon.
What happens if you ignore ear pain
Mild ear pain sometimes goes away on its own, especially if it is from pressure or minor inflammation. But untreated bacterial infections can spread. The infection can move deeper into the middle ear, rupture the eardrum (which causes drainage but often relieves pain temporarily), or spread to the bone behind the ear.
A ruptured eardrum usually heals on its own, but it can cause permanent hearing loss if it happens repeatedly. Infection spreading to the bone (mastoiditis) is rare now because of antibiotics, but it is serious and requires hospital treatment. These complications are why doctors recommend seeing someone for ear pain that lasts more than a few hours.
In children, untreated ear infections can also delay speech development if hearing loss happens during the critical learning period. This is another reason to have ear pain checked promptly in young children.
Home care while you wait to see a doctor
Over-the-counter pain relievers like ibuprofen or acetaminophen can reduce ear pain and fever while you arrange a doctor's visit. Follow the dosing on the package for your age and weight. A warm compress held against the outside of the ear may also ease discomfort.
Avoid putting anything into the ear canal—no cotton swabs pushed deep, no water, no home remedies. If fluid is draining, let it drain and keep the area clean with a tissue. Do not plug the ear with cotton unless your doctor tells you to.
If you have a fever, rest and drink fluids. These steps support your body while it fights the infection, but they are not a substitute for a doctor's evaluation. Home care buys you comfort until you can be seen, not a cure.
Frequently Asked Questions
Can you have an ear infection without pain?
Yes. Some people, especially children, have fluid behind the eardrum with hearing loss but little or no pain. Others have mild discomfort they do not notice. If you have hearing loss in one ear, drainage, or a feeling of fullness that lasts more than a few days, see a doctor even without pain.
Does earwax buildup feel like an ear infection?
It can. Earwax can cause ear pain, hearing loss, and a feeling of fullness. The difference is that earwax buildup does not usually come with fever or drainage, and it does not follow a cold. A doctor can see the difference with an otoscope and remove earwax safely if that is the problem.
What if my ear pain goes away on its own?
Pain that goes away in a few hours was likely pressure or minor inflammation, not a bacterial infection. But if it comes back, lasts more than a few hours, or is severe, see a doctor. Even if pain stops, drainage or hearing loss means an infection may still be present and needs checking.
Can allergies or sinus problems cause ear pain?
Yes. Sinus pressure and swelling from allergies can cause ear pain and a feeling of fullness. This pain usually improves as the sinus or allergy symptoms improve. But if pain is severe, comes with fever, or includes drainage, an infection may have developed on top of the sinus or allergy problem.
Is it safe to fly with an ear infection?
Flying with an active ear infection can be painful because cabin pressure changes stress the Eustachian tube. If you have ear pain, fever, or drainage, postpone flying until a doctor has seen you and cleared it. If you must fly, ask your doctor about decongestants or other steps to manage pressure changes.
