An ear infection typically feels like a deep, persistent ache inside the ear, often accompanied by a sensation of fullness or pressure, as if your ear is stuffed with cotton or submerged underwater. The exact combination of symptoms depends on which part of the ear is infected, but pain, muffled hearing, and that plugged-up feeling are the most common experiences across all types.
The Core Sensations
The hallmark of an ear infection is pain that builds over hours and doesn’t let up. With a middle ear infection (the most common type), the pain sits deep inside the ear and often feels like pressure pushing outward. Fluid trapped behind the eardrum creates that pressure, and in some cases it builds enough to actually tear the eardrum. If that happens, you’ll typically feel a sudden sharp pain followed by relief as the pressure drops, and you may notice fluid draining from the ear.
With an outer ear infection (sometimes called swimmer’s ear), the sensation is different. The pain tends to be more of a burning or stinging feeling in the ear canal itself, and itchiness is a major feature. Touching or pulling on the outer ear usually makes it worse. The ear canal often feels swollen and blocked.
Both types can cause muffled hearing, almost like you’re listening through a wall. This happens because fluid buildup or swelling prevents sound from traveling normally. Some people also hear ringing, buzzing, or popping sounds inside the affected ear.
Pressure, Fullness, and the “Underwater” Feeling
One of the most distinctive and frustrating sensations is a persistent feeling of fullness, like your ear needs to pop but won’t. This comes from fluid buildup behind the eardrum or from the small tubes that connect your middle ear to your throat (the eustachian tubes) failing to open and equalize pressure the way they normally do. People often describe it as hearing the world through a thick blanket. Yawning, swallowing, or chewing gum may temporarily ease it, but with an active infection the feeling tends to return quickly.
Beyond Ear Pain
Ear infections don’t always stay contained to the ear. Fever and headache frequently come along for the ride, especially with middle ear infections. Some people experience dizziness or a spinning sensation (vertigo) because the structures responsible for balance sit right next to the infection. Nausea can follow, particularly when the dizziness is strong. You might also notice warmth, redness, or swelling on or around the outer ear.
Drainage from the ear can take several forms. It might be thin and clear, thick and yellowish or greenish, or occasionally tinged with blood. It can be odorless or foul-smelling. Any drainage means something is leaking that shouldn’t be, and thicker, discolored, or smelly discharge generally signals a more significant infection.
What It Feels Like for Babies and Young Children
Children under two or three can’t describe their symptoms, so ear infections show up as behavior changes. The most recognizable sign is unusual fussiness, especially when lying down. Lying flat increases pressure on the middle ear, which intensifies the pain. Babies may also refuse to eat because swallowing changes the pressure in their ears and hurts.
Ear tugging gets a lot of attention as a symptom, but it’s worth knowing that babies naturally discover their ears around four months of age and will poke at them simply because they’re there, especially when teething or trying to fall asleep. Ear pulling alone isn’t a reliable indicator. Combined with fever, irritability, trouble sleeping, or drainage, though, it becomes more meaningful.
How Long the Pain Lasts
Most ear infections cause their worst pain in the first 48 to 72 hours. Many mild to moderate infections begin to improve on their own within that window, which is why doctors sometimes recommend a “watch and wait” approach before prescribing antibiotics, particularly for older children and adults with less severe symptoms. If pain persists beyond 48 hours or gets noticeably worse during that period, that’s considered a sign of more severe disease that likely needs treatment.
Even after the acute pain fades, the muffled hearing and fullness can linger for days or sometimes weeks as the fluid behind the eardrum slowly drains and absorbs. This is normal and doesn’t necessarily mean the infection is still active.
Signs of a Serious Complication
Occasionally, an ear infection spreads to the bone behind the ear, a condition called mastoiditis. The warning signs are distinct: throbbing ear pain that won’t go away or keeps getting worse, swelling or redness behind the ear (which may look purplish on darker skin), the affected ear visibly sticking out more than the other, and a soft or doughy feeling when you press the bone behind the ear. Fever, worsening hearing loss, pus-like drainage, confusion, double vision, or facial weakness alongside ear pain all signal that the infection has moved beyond the middle ear and needs urgent attention.
Untreated mastoiditis can lead to serious problems including significant hearing loss, infection of the membranes around the brain, or widespread infection throughout the body. These complications are uncommon, but they’re the reason persistent or worsening ear pain shouldn’t be brushed off.
