The most common symptom of an ear infection is pain, ranging from a dull ache to sharp, intense pressure inside the ear. Other typical signs include muffled hearing, fluid drainage, and fever. The specific symptoms depend on which part of the ear is affected, and they look quite different in adults compared to babies and young children who can’t describe what they’re feeling.
Middle Ear Infection Symptoms
Middle ear infections (otitis media) are the most common type, especially in children. They happen when fluid builds up behind the eardrum and becomes infected. The hallmark symptom is a deep, throbbing pain inside the ear that often gets worse when lying down. You may also notice muffled or reduced hearing in the affected ear, since trapped fluid prevents the eardrum from vibrating normally.
Fever frequently accompanies a middle ear infection. In children 6 months and older, a temperature of 102.2°F (39°C) or higher alongside ear pain signals a more severe infection. Many middle ear infections also cause a feeling of fullness or pressure, similar to what you’d feel during altitude changes on an airplane, except it doesn’t go away with swallowing or yawning.
Sometimes the pressure from fluid buildup becomes intense enough to rupture the eardrum. When this happens, you’ll often feel a sudden relief from pain followed by thick yellow fluid draining from the ear. While a burst eardrum sounds alarming, most heal on their own within a few weeks. If drainage continues over time, turning white, yellow, or green, the infection may have become chronic.
How Symptoms Show Up in Babies and Toddlers
Young children get ear infections far more often than adults, but they can’t tell you their ear hurts. Instead, watch for behavioral changes. Tugging or pulling at the ear is one of the most recognized signs, though not every child does this. Fussiness and unusual crying, particularly when lying down, are common because the horizontal position increases pressure on the middle ear.
Trouble sleeping is another frequent signal. A child who was sleeping through the night may suddenly wake up crying or resist being put down. Loss of appetite often accompanies ear infections too, since chewing and swallowing can change the pressure in the middle ear and make pain worse. Some children also have trouble with balance or seem clumsier than usual.
For infants under 3 months, any fever of 100.5°F (38°C) or above warrants an immediate call to a pediatrician, regardless of other symptoms. For older children, a fever above 104°F (40°C) is a red flag that needs prompt medical attention.
Outer Ear Infection (Swimmer’s Ear)
Outer ear infections affect the ear canal rather than the space behind the eardrum. They often start with itching inside the ear, which progresses to pain over a day or two. The key distinguishing feature: the pain gets significantly worse when you touch, pull, or wiggle the earlobe. Middle ear infections don’t typically respond to external touch this way.
As the infection develops, the ear canal swells, which can partially block hearing and make the ear feel plugged. Pain may radiate from the ear to the head, neck, or side of the face. Outer ear infections are especially common after swimming or in humid environments, which is why this type is often called swimmer’s ear. Unlike middle ear infections, fever is less common with outer ear infections unless the infection becomes severe.
Inner Ear Infection Symptoms
Inner ear infections are less common but produce distinctly different symptoms. The inner ear controls both hearing and balance, so when it becomes inflamed (a condition called labyrinthitis), the primary symptoms are intense vertigo and hearing changes rather than ear pain. Vertigo from an inner ear infection makes you feel like the room is spinning around you, and it can come on suddenly.
Other symptoms include nausea and vomiting triggered by the vertigo, difficulty concentrating, blurred vision, ringing in the ear (tinnitus), and significant balance problems that make walking difficult. These symptoms tend to be most severe in the first few days and gradually improve, though balance issues can linger for weeks. If you experience vertigo and dizziness without hearing loss, the inflammation may be affecting only the balance nerve rather than the full inner ear.
What Ear Drainage Tells You
Fluid leaking from the ear is a common ear infection symptom, and its color and consistency offer clues about what’s going on. Thick yellow or green fluid typically means pus from a bacterial infection, often after the eardrum has ruptured from pressure. This drainage usually brings noticeable pain relief because the pressure has been released.
Clear fluid can come from less severe irritation or conditions like ear eczema. However, clear or blood-tinged fluid following any head injury is a medical emergency, as it could indicate fluid leaking from around the brain. Bloody drainage without a head injury may suggest a foreign object in the ear, which is particularly common in young children who insert small toys or other items.
When Symptoms Signal Something Serious
Most ear infections resolve on their own or with basic treatment. The CDC recommends a watchful waiting approach of 2 to 3 days for many childhood ear infections, giving the immune system time to fight the infection before starting antibiotics. Many children improve within that window without medication.
Certain symptoms, however, suggest a complication that needs prompt attention. Mastoiditis, an infection that spreads to the bone behind the ear, causes pain, redness, and swelling behind the ear that can actually push the ear forward so it visibly sticks out. Other warning signs include a high fever alongside the swelling, hearing loss in the affected ear, headache, and increasing irritability or fatigue. On darker skin tones, redness behind the ear may be harder to spot, so swelling and tenderness are more reliable indicators.
If an ear infection doesn’t improve after 2 to 3 days of observation, or if symptoms worsen at any point during that period, that’s the signal to move from watching and waiting to active treatment. Persistent drainage lasting more than a few days, facial weakness on the side of the infected ear, or severe headache with neck stiffness also warrant urgent evaluation.
