The most common signs of an ear infection are ear pain, muffled hearing, and a feeling of fullness or pressure inside the ear. In young children who can’t describe what they feel, the signs look different: tugging at the ear, unusual fussiness, and trouble sleeping. Symptoms typically develop quickly, often during or just after a cold, and most improve within two to three days.
Signs in Adults
Adults with a middle ear infection usually notice a sharp or dull pain deep inside the ear, sometimes described as pressure that won’t equalize. Hearing on the affected side often becomes muffled, as if you’re listening through a wall. Some people also experience fluid draining from the ear, which can mean the eardrum has ruptured under pressure. While that sounds alarming, a small rupture usually heals on its own within a few weeks, and the pain often drops immediately once the pressure releases.
Fever is less common in adults than in children but can still occur, particularly with a more severe infection. You might also notice a general sense of being unwell, dizziness, or mild balance problems, since the middle ear plays a role in spatial orientation.
Signs in Babies and Young Children
Children under two or three can’t tell you their ear hurts, so the signs are mostly behavioral. Watch for:
- Tugging or pulling at one or both ears
- Increased crying and irritability, especially when lying down (which shifts pressure onto the eardrum)
- Trouble sleeping or waking more frequently at night
- Fever, which is more common in infants and toddlers than in older children
- Fluid draining from the ear
- Clumsiness or balance problems, such as stumbling more than usual
- Not responding to quiet sounds, which can signal temporary hearing loss from fluid buildup
These symptoms often appear alongside or just after an upper respiratory infection. A child who has had a runny nose for several days and then suddenly becomes more irritable or develops a fever is a classic picture. Doctors confirm the diagnosis by looking at the eardrum with a small scope. A bulging, red eardrum with fluid behind it is the hallmark finding.
Middle Ear Infection vs. Swimmer’s Ear
Not all ear infections are the same, and the signs differ depending on where the infection sits. A middle ear infection (otitis media) happens behind the eardrum, usually triggered by bacteria or viruses that travel up from the throat. Swimmer’s ear (otitis externa) is an infection of the ear canal itself, the tube between the outer ear and the eardrum.
The easiest way to tell them apart at home: gently tug on the outer ear or press on the small flap of cartilage in front of the ear canal. If that causes pain, swimmer’s ear is more likely. Middle ear infections don’t usually hurt with external touch. Swimmer’s ear also tends to cause itchiness inside the ear canal, visible redness and swelling around the ear opening, and drainage. It’s common after swimming or prolonged moisture exposure, while middle ear infections typically follow colds or allergies.
What Ear Drainage Can Tell You
Fluid coming from the ear is one of the more noticeable signs, and its appearance gives clues about what’s happening. Thick yellow or green discharge usually points to a bacterial infection, often from a middle ear infection that has caused the eardrum to rupture. You might have severe pain that suddenly improves right before the drainage starts.
White or yellowish fluid that drains without much pain can indicate a chronic ear infection, one that has been present for weeks or longer. Clear fluid from the ear is less common with infections and may be related to skin conditions like eczema in the ear canal. Clear or blood-tinged fluid after a head injury is a medical emergency, as it can signal a skull fracture.
How Long Symptoms Typically Last
Most middle ear infections improve on their own within two to three days. Pain is usually worst in the first 24 to 48 hours, then gradually fades. Muffled hearing can linger for a week or two after the infection clears, since trapped fluid behind the eardrum takes time to drain through the narrow tube that connects the middle ear to the throat.
Many ear infections, particularly in children over two with mild symptoms, don’t need antibiotics right away. A common approach is watchful waiting for two to three days to see if the immune system clears the infection on its own. If symptoms persist, worsen, or are severe from the start, antibiotics are typically started without delay. Children under six months and those with high fevers or infections in both ears usually receive treatment immediately.
Signs the Infection May Be Spreading
Complications from ear infections are uncommon, but recognizing the warning signs matters. The most significant is mastoiditis, an infection of the bone directly behind the ear. Signs include pain, redness, and swelling behind the ear that can cause it to visibly stick out. A high temperature, headache, hearing loss, and unusual tiredness or irritability alongside the swelling are red flags. Redness behind the ear can be harder to spot on darker skin tones, so tenderness and swelling are more reliable indicators.
Other signs that warrant prompt medical attention include a fever above 102.2°F (39°C), symptoms that suddenly get worse after seeming to improve, drainage that contains blood (without a recent head injury), or facial weakness on the same side as the infected ear. Persistent symptoms lasting beyond two to three days without any improvement also signal the need for evaluation.
