Signs of Ear Infection: Symptoms in Adults & Children

Ear pain has a way of making everyone miserable—whether it’s a toddler tugging at their ear at 2 a.m. or an adult suddenly struggling to hear clearly. Spotting an ear infection early can mean faster relief, fewer trips to urgent care, and less suffering overall. This guide walks through the signs of ear infection across all ages, from the classic symptoms to the subtle cues that are easy to miss.

High temperature threshold: 38°C or above · Most common symptom: Ear pain · Common in children: Acute otitis media · Hearing impact: Temporary loss · Discharge indicator: Possible fluid from ear

The key facts table below summarizes the primary causes, peak age groups, and complications to watch for.

How can you tell if your ear has an infection?

Ear infections share a handful of hallmark signs that show up across age groups, though the way they present can vary significantly.

General signs and symptoms

Pain inside the ear remains the most reliable indicator. The National Institute on Deafness and Other Communication Disorders notes that acute otitis media (AOM) is the most common ear infection type, causing pain and fever due to fluid trapped behind the eardrum. Beyond pain, you may notice a high temperature of 38°C or above, difficulty hearing, and fluid or discharge running out of the ear—a sign that warrants prompt attention (CDC).

Pain and pressure indicators

The sensation often builds as pressure builds behind the eardrum. In infants, lying down can intensify this pressure, making them more irritable and prone to crying, especially at night (Riley Children’s Health). Adults typically describe a feeling of fullness or blockage alongside the pain.

The implication: waiting it out only makes sense if symptoms stay mild and no discharge appears. Once fluid starts draining, the eardrum has likely ruptured and professional care is needed.

What are the symptoms of an ear infection in adults?

Adults experience many of the same symptoms as children, but the presentation tends to be more verbal and specific.

Inner ear vs middle ear signs

Middle ear infections in adults commonly bring ear pain or pressure, fluid drainage, and trouble hearing (Mayo Clinic). Inner ear involvement may add dizziness, balance problems, and muffled hearing that worsens over hours or days. Adults may also experience sore throat, fever, and jaw pain alongside the ear symptoms (Lawrence Otolaryngology Associates).

Hearing loss and fullness

The feeling of fullness or blockage in the ear is particularly common in adults and often follows sinus issues or recent colds (Pedi-Care Pediatrics). Temporary hearing loss from fluid buildup typically resolves once the infection clears, according to Children’s ENT specialists. Severe symptoms like sudden hearing loss, intense pain, or significant dizziness require prompt medical attention.

The pattern: if an adult develops ear pain after a cold or sinus infection, the infection likely traveled upward from the respiratory tract. Treating the underlying sinus issue often helps resolve the ear problem faster.

What are signs of ear infection in child?

Children display a wider range of symptoms than adults, partly because they can’t always articulate what they’re feeling. Behavioral cues become just as important as verbal complaints.

Signs in babies

Babies show ear infection signs through excessive crying, ear tugging, sleep disturbances, fever, and ear drainage (Children’s ENT specialists). While the most obvious symptom is pain in the ear, a very young child likely won’t be able to verbalize this, according to Penn Medicine healthcare providers. Ear tugging may indicate infection but can also be exploratory behavior—confirm with other symptoms like fever before assuming an infection is present (Children’s ENT specialists).

Signs in breastfed babies

Breastfed infants may refuse feeds or show reduced appetite during an ear infection. Diarrhea, vomiting, or reduced appetite can accompany ear infections in children due to viral cause (UnityPoint Health medical team). Watch for clumsiness or balance problems—babies may become unsteady on their feet if inner ear involvement affects their equilibrium.

The catch: toddlers can’t tell you their ear hurts. Ear tugging, unusual fussiness, crying more than usual, trouble sleeping, and loss of appetite together paint a clearer picture than any single symptom alone (Mayo Clinic medical experts).

What could be mistaken for an ear infection?

Several conditions share overlapping symptoms with ear infections, leading to misdiagnosis if you rely solely on ear pain as the indicator.

Common misdiagnoses

Teething pain in infants can cause ear-area discomfort and irritability that resembles infection symptoms. Sinus issues create pressure and pain that radiate to the ear region. TMJ disorders cause jaw pain that patients sometimes perceive as ear pain. Upper respiratory infections block the Eustachian tubes, creating fullness and muffled hearing without actual infection (Cleveland Clinic health professionals).

Three finger test explanation

The so-called “three finger test” is sometimes mentioned as a home method to check for eardrum perforation—placing three fingers across the ear canal area to apply gentle pressure. However, this method lacks medical validation and should not replace professional examination. Swimmer’s ear (otitis externa) presents differently from middle ear infection, with symptoms including itchiness, redness, and swelling of the outer ear canal rather than deep ear pain (Rush Children’s Hospital specialists).

The implication: ear pain alone isn’t enough to diagnose an infection. The combination of pain, fever, and hearing changes together points more reliably toward otitis media.

Will an ear infection go away on its own?

Many ear infections resolve without antibiotics, but the decision to wait depends on symptom severity, age, and how long the infection persists.

Factors for self-resolution

Mild ear infections often clear within 2–3 days as the immune system fights off the underlying virus or bacteria. Watchful waiting is a common approach for children over 6 months with mild symptoms, according to CDC public health guidance. However, viral infections cannot be treated with antibiotics—only bacterial infections respond to them.

When to seek help

Seek care for significant ear pain, drainage, fever over 102.2°F (39°C), worsening hearing, or balance issues (CDC public health guidance). Children under 6 months require immediate medical attention for any fever or suspected ear infection. If symptoms worsen after 48–72 hours or show no improvement, a healthcare provider should evaluate the situation.

What this means: mild cases often resolve on their own with rest and symptom management. But fever above 39°C, fluid drainage, or symptoms lasting beyond three days mean professional treatment is necessary to prevent complications.

While the most obvious symptom of an ear infection is pain in the ear, a very young child likely won’t be able to verbalize this.

A sure sign of an ear infection is fluid or pus draining out of a child’s ear.

Ear infections are most common in children under 2 years old. They typically start to outgrow ear infections by about ages 3–5.
