What symptoms mean you likely have an ear infection
The clearest sign of an ear infection is ear pain that comes on suddenly, especially if it follows a cold or sore throat. The pain can range from a dull ache to sharp stabbing, and it often gets worse when you pull on your earlobe or press on the small bump in front of your ear canal. You may also notice fluid draining from your ear—this can be clear, yellowish, or bloody.
Other common signs include hearing loss in the affected ear, a feeling of fullness or pressure inside your ear, fever (usually low-grade, around 100 to 102°F), and sometimes dizziness or balance problems. Children may tug at their ears, cry more than usual, or have trouble sleeping. Not everyone has all these symptoms; some people have only ear pain and mild hearing loss.
The key difference between an ear infection and other ear problems is that the pain and other symptoms develop quickly—usually within hours or a day or two—rather than gradually over weeks. If you had normal hearing and comfort yesterday and woke up with ear pain today, an infection is a reasonable possibility.
Key Takeaways
- Sudden ear pain, especially after a cold, is the most common sign of an ear infection, and it often worsens when you touch the outer ear.
- Fluid drainage from your ear, hearing loss, or a feeling of fullness inside your ear are also typical signs that warrant a doctor's visit.
- Fever and balance problems can occur with ear infections but are less common than pain and hearing changes.
- A doctor needs to look inside your ear with an otoscope to confirm an infection; you cannot diagnose it yourself from symptoms alone.
When ear pain is not an infection
Ear pain can come from many sources that are not infections. Swimmer's ear (outer ear canal irritation) causes pain when you tug on your earlobe or chew, but usually no fever or systemic illness. Earwax buildup creates a feeling of fullness and muffled hearing but typically no sharp pain. Temporomandibular joint (TMJ) problems cause pain that feels like it is in or near the ear but is actually from your jaw joint.
Sinus pressure from a cold or allergies can also feel like ear pain, especially a dull ache or fullness. Tooth pain from a cavity or abscess sometimes radiates to the ear. Tension headaches and migraines can produce ear-related discomfort. The difference is usually timing and what else is happening: an infection comes on fast with fever and systemic symptoms, while these other causes tend to develop gradually or come with other obvious signs (jaw clicking, sinus congestion, tooth sensitivity).
What a doctor will do to confirm an infection
Your doctor will use a tool called an otoscope to look inside your ear canal and at your eardrum. They are looking for redness, swelling, fluid behind the eardrum, or pus. A healthy eardrum is pearly gray and translucent; an infected one is often red, bulging, or cloudy. Your doctor may also perform a simple test called tympanometry, which measures how well your eardrum moves—fluid behind it prevents normal movement.
If you have drainage, your doctor may send a sample to a lab to identify which bacteria or virus is causing the infection. This helps determine the right treatment, especially if antibiotics are needed. Your doctor will also ask about your symptoms, when they started, whether you have had recent colds or sinus problems, and whether you have had ear infections before.
Ear infections in children versus adults
Children get ear infections more often than adults because their Eustachian tubes (the passages that drain fluid from the middle ear) are shorter and more horizontal, making fluid buildup easier. A child with an ear infection may not be able to tell you where it hurts; instead, watch for tugging at the ear, excessive crying, trouble sleeping, fever, or fluid draining from the ear. Some children become irritable or lose their appetite.
Adults usually have more obvious symptoms because they can describe the pain precisely. Adult ear infections are often more serious or long-lasting because the anatomy that protects children's ears has changed. If an adult develops a sudden ear infection without a recent cold, a doctor should rule out other causes like a ruptured eardrum or a more serious infection.
How long symptoms last before you should see a doctor
If you have ear pain with fever, see a doctor within 24 hours. If you have ear pain without fever but it is severe or you have drainage, contact a doctor within a day or two. Mild ear discomfort that lasts only a few hours may resolve on its own, especially if it follows air travel or water exposure, but pain that persists for more than a few hours warrants a call to your doctor's office.
Do not wait to see a doctor if you have hearing loss, dizziness, or drainage—these suggest the infection may have progressed. Children with fever and ear pain should be seen by a doctor the same day if possible. If you cannot reach your regular doctor, an urgent care clinic can examine your ear and start treatment.
What to do while waiting for a doctor's appointment
Over-the-counter pain relievers like ibuprofen or acetaminophen can reduce ear pain and fever while you wait to be seen. A warm compress held against the outside of your ear may also ease discomfort. Avoid inserting anything into your ear canal, including cotton swabs, as this can worsen irritation or push infection deeper.
If you have drainage, gently wipe it away with a clean tissue, but do not plug your ear or try to stop the drainage—it is your body's way of releasing pressure. Stay upright rather than lying flat, as this helps fluid drain naturally. Avoid loud noise and sudden pressure changes (like flying or diving) until a doctor has examined you.
Red flags that mean you need urgent care
Seek urgent or emergency care if you develop severe ear pain with high fever (above 103°F), dizziness or vertigo that makes it hard to walk, hearing loss in both ears, or swelling and redness behind or around your ear. These can signal a more serious infection spreading beyond the middle ear. Stiff neck with ear pain and fever is rare but serious and requires immediate evaluation.
If you have had an ear infection treated with antibiotics and your symptoms return or worsen after a few days, contact your doctor again. This may mean the infection is resistant to the antibiotic you were given, or a different problem is developing.
Frequently Asked Questions
Can you have an ear infection without pain?
Yes, though it is less common. Some people notice only hearing loss, fullness in the ear, or drainage without significant pain. This is more likely in adults than children. If you have these symptoms, a doctor should still examine your ear to rule out infection or other causes.
Does an ear infection always cause fever?
No. Many ear infections, especially in adults, occur without fever. Pain, drainage, or hearing loss can be present without any rise in body temperature. Fever is more common in children and in more severe infections, but its absence does not mean you do not have an infection.
Can you catch an ear infection from someone else?
The infection itself is not contagious, but the cold or virus that triggers it is. If you catch a cold from someone, you may develop an ear infection as a complication. Ear infections are not spread directly from person to person the way a cold is.
How do I know if it is my inner ear or middle ear that is infected?
Middle ear infections cause ear pain, drainage, and hearing loss. Inner ear infections (labyrinthitis) cause dizziness, vertigo, and balance problems, sometimes with hearing loss, but usually without drainage or severe ear pain. Only a doctor can tell the difference by examining you and sometimes ordering imaging tests.
Is it normal for ear pain to come and go?
Intermittent ear pain can happen with some infections, especially as pressure builds and releases. However, pain that comes and goes over days or weeks is less typical of a straightforward infection and may point to something else, like TMJ problems or referred pain from your sinuses or teeth. A doctor should evaluate it.
