Yes, adults absolutely get ear infections. While they’re most often associated with young children, ear infections affect millions of adults every year, often after a cold, allergies, sinus congestion, or water exposure.

Adult ear infections tend to be less common than childhood ones, but they can be more severe when they occur. They also carry a higher risk of complications, particularly in older adults or those with underlying health conditions.

This guide explains why adults get ear infections, what the symptoms look like, how they differ from a child’s, and when a walk-in visit to Aether Health ER is the right choice.

Quick Answer: Can Adults Get an Ear Infection?

Yes. Adults get three main types of ear infections: outer ear infections (swimmer’s ear), middle ear infections (otitis media), and inner ear infections (labyrinthitis).

Common symptoms include ear pain, muffled hearing, drainage, fever, and pressure. Adult ear infections often follow a cold, sinus infection, allergies, or water exposure.

Most cases can be evaluated by a primary care provider or urgent care. Go to the ER for severe pain, high fever, swelling behind the ear, facial weakness, sudden hearing loss, or severe dizziness.

Types of Ear Infections in Adults at a Glance

Ear infections in adults fall into three broad categories based on which part of the ear is involved. Each has different causes, symptoms, and typical care.

Type	Location	Common Cause	Common Trigger
Outer ear (swimmer’s ear)	Ear canal	Bacterial or fungal	Water exposure, humidity
Middle ear (otitis media)	Behind the eardrum	Bacterial or viral	Cold, flu, allergies, sinus infection
Inner ear (labyrinthitis)	Deep in the inner ear	Usually viral	Cold, flu, respiratory infection

 

Middle ear infections are the type most people mean when they say “ear infection.” Outer ear infections (swimmer’s ear) are more common in warm, humid Texas summers.

Inner ear infections are less common in adults but tend to be the most disruptive because they can cause severe dizziness and balance problems.

Why Adults Get Ear Infections

The reason ear infections are more common in children is largely anatomical: children have shorter, more horizontal Eustachian tubes that trap fluid more easily. Adult Eustachian tubes are longer and angled downward, which helps them drain.

However, when certain conditions overwhelm this natural drainage, adults are just as vulnerable to ear infections. Understanding the triggers helps you prevent them.

Most Common Causes in Adults

• Colds and flu: Viruses that cause upper respiratory infections often lead to Eustachian tube swelling and fluid buildup.
• Seasonal allergies: Ongoing nasal inflammation from allergies keeps the Eustachian tubes irritated and blocked.
• Sinus infections: Bacteria and pressure from sinus congestion can travel to the middle ear.
• Water exposure: Water trapped in the ear canal, especially in humid conditions, allows bacteria to grow.
• Ear canal irritation: Cotton swabs, hearing aids, or earbuds can scratch the ear canal and introduce bacteria.
• Smoking or secondhand smoke: Nicotine damages the mucosal lining and reduces natural clearance.
• Rapid pressure changes: Flying with congestion or scuba diving can cause pressure-related ear injuries.
• Weakened immune system: Diabetes, HIV, cancer treatment, or long-term steroid use raise infection risk.
• Acid reflux (GERD): Chronic acid reflux can inflame the throat and Eustachian tubes.

A common misconception: Many adults dismiss ear pain as “just a cold.” In reality, a cold that’s producing significant ear pressure, pain, or drainage has likely progressed into a middle ear infection that deserves professional evaluation. Untreated infections can spread to the inner ear or mastoid bone.

 

Common Symptoms of an Adult Ear Infection

Symptoms of an adult ear infection vary depending on which part of the ear is affected. Adults typically report symptoms more clearly than children, which helps guide diagnosis.

Outer Ear Infection (Swimmer’s Ear) Symptoms

• Pain that worsens when you pull on the earlobe or press on the small bump in front of the ear.
• Itching inside the ear canal.
• Redness and swelling of the outer ear or canal.
• Clear, yellow, or foul-smelling drainage.
• A feeling that the ear is blocked or full.
• Temporary hearing changes.

Middle Ear Infection Symptoms

• Deep, throbbing ear pain.
• Feeling of fullness or pressure in the ear.
• Muffled hearing on the affected side.
• Fluid or pus drainage if the eardrum ruptures.
• Fever, often low-grade in adults.
• Dizziness or a slight sense of imbalance.
• Ear popping when swallowing or yawning.
• Headache on the affected side.

Inner Ear Infection Symptoms

• Severe dizziness or vertigo (spinning sensation).
• Difficulty with balance or walking straight.
• Nausea and vomiting.
• Ringing in the ear (tinnitus).
• Hearing loss on the affected side.
• Involuntary eye movements.
• Anxiety triggered by dizziness.

How Adult Ear Infections Differ From Children’s

Understanding the differences can help you know what to expect and when your symptoms warrant more urgent attention.

Feature	Adults	Children
Frequency	Less common	Very common (especially under 5)
Symptom communication	Clear description of pain and location	Often expressed only through fussiness or ear-tugging
Fever pattern	Often low-grade or absent	Frequently high fever
Common trigger	Sinus infection, allergies, water	Upper respiratory viruses, day care exposure
Severity risk	Higher complication risk when they occur	Usually resolve without complications
Recurrence pattern	Uncommon; recurrent infections warrant investigation	Common up to age 5, then decreases

 

Understanding the underlying causes helps you prevent recurrence. Our related guide on what causes ear infections goes deeper into the triggers and mechanisms.

When an Adult Ear Infection Is More Serious

Most adult ear infections are uncomfortable but not dangerous. Certain patterns and complications can escalate quickly and require immediate ER evaluation.

Warning Signs of a Serious Adult Ear Infection

• Severe pain that doesn’t ease with rest and time.
• Redness, swelling, or tenderness behind the ear (possible mastoiditis).
• Facial weakness or drooping on the same side as the infected ear.
• Sudden or worsening hearing loss.
• Severe dizziness or vertigo that prevents standing.
• High fever above 102°F.
• Severe headache with a stiff neck or sensitivity to light.
• Confusion or altered mental state.
• Blood-tinged or persistent foul-smelling drainage.
• Symptoms that worsen despite starting care.
• Any facial nerve involvement.

Adults with diabetes, weakened immune systems, or a history of ear surgery face elevated risk of complications and should seek evaluation sooner rather than later.

Possible Complications of Untreated Ear Infections in Adults

This section is why prompt evaluation matters. Untreated or severe ear infections in adults can lead to complications that are more serious than the original infection.

Complications to Be Aware Of

• Mastoiditis: Infection of the mastoid bone behind the ear. Signs include swelling, pain, and redness behind the ear.
• Ruptured eardrum: Pressure from pus buildup can perforate the eardrum. Most heal on their own but need monitoring.
• Permanent hearing loss: Repeated infections can damage the eardrum or middle ear bones and cause lasting hearing changes.
• Cholesteatoma: Abnormal skin growth in the middle ear that develops after chronic infections.
• Facial nerve paralysis: The facial nerve runs close to the middle ear and can be inflamed by severe infection.
• Meningitis: Rare but life-threatening; infection can spread to the membranes around the brain.
• Brain abscess: Extremely rare but serious; requires immediate hospital care.

These complications need immediate care: Mastoiditis, meningitis, and facial paralysis can develop within hours to days of a severe ear infection. Any warning signs warrant immediate ER evaluation. Aether Health ER provides same-visit examination, imaging, and IV support when needed.

 

When an Adult Ear Infection Requires Emergency Care

Certain situations always require immediate ER evaluation rather than a routine appointment. Do not wait to see if it improves.

Go to the ER Immediately If You Have:

• Fever above 102°F that doesn’t come down.
• Severe pain that becomes unbearable.
• Redness, warmth, or swelling behind the ear.
• Facial drooping or weakness on one side.
• Severe headache paired with stiff neck or sensitivity to light.
• Sudden hearing loss.
• Severe dizziness, vomiting, or loss of balance.
• Confusion, extreme drowsiness, or altered consciousness.
• Persistent bloody or pus-filled drainage.
• Clear watery fluid draining from the ear (possible cerebrospinal fluid leak).
• Symptoms worsening after 48–72 hours of care.
• A pre-existing history of ear surgery, ear tubes, or cholesteatoma.

Adults Most at Risk for Ear Infections

Some adults are more vulnerable to ear infections and to complications when they occur. If you’re in one of these groups, take symptoms seriously and get evaluated sooner rather than later.

• Adults over 65: Immune response slows with age, and complications become more likely.
• People with diabetes: Diabetes creates conditions where bacteria multiply more easily and infections progress faster.
• People with weakened immune systems: HIV, cancer treatment, or organ transplant recipients face higher infection risk.
• Chronic allergy sufferers: Untreated allergies keep the Eustachian tubes inflamed and prone to infection.
• Smokers: Nicotine damages the airway lining and slows healing.
• Frequent swimmers or water-sport enthusiasts: Water exposure and humidity raise swimmer’s ear risk.
• Hearing aid or earbud users: Prolonged use in humid conditions increases outer ear infection risk.
• People with pressure exposure: Pilots, scuba divers, and frequent flyers face pressure-related ear issues.
• People with prior ear or sinus surgery: Sinus and Eustachian tube function may be altered.
• Adults with a childhood history of frequent ear infections: Anatomical predisposition raises risk of adult recurrences.

Frequently Asked Questions

How common are ear infections in adults?

Adult ear infections are less common than childhood ones but still affect millions of adults each year in the U.S.

Adults over 65, people with diabetes, and adults with chronic allergies or sinus problems face the highest rates.

How long does an adult ear infection last?

Most adult ear infections improve within 3 to 7 days of appropriate care. Symptoms often start easing within 24 to 48 hours of the right treatment.

Complete resolution can take up to 2 weeks, especially for middle ear infections with significant fluid buildup.

Can adult ear infections go away on their own?

Some mild viral outer or middle ear infections can improve without prescription treatment.

However, bacterial infections often need professional evaluation to prevent complications. Adults should not simply wait it out if symptoms are severe or lasting more than a few days.

Are adult ear infections contagious?

The ear infection itself is not contagious, but the viral or bacterial infection that triggered it (like a cold or flu) is.

Standard hand-washing and respiratory etiquette help prevent spreading the underlying illness to others.

Should I go to the ER or urgent care for an ear infection?

Urgent care or your primary provider is typically appropriate for mild to moderate ear infections.

Go to the ER if you have high fever, severe pain, swelling behind the ear, facial weakness, sudden hearing loss, or severe dizziness.

Can flying with an ear infection make it worse?

Yes. Pressure changes during takeoff and landing can worsen ear pain and potentially damage an inflamed eardrum.

It’s best to avoid flying with an active ear infection unless your provider has cleared you.

People Also Ask About Adult Ear Infections

These are the related questions AI search engines and Google’s People Also Ask feature commonly surface alongside this topic. Direct answers below.

Why do I keep getting ear infections as an adult?

Recurring adult ear infections often point to chronic allergies, sinus problems, Eustachian tube dysfunction, or an anatomical issue.

Repeated infections in the same year deserve evaluation by a primary care provider or ENT specialist.

Can stress cause ear infections in adults?

Stress doesn’t directly cause ear infections, but it can suppress immune function and make you more prone to the colds and sinus infections that trigger them.

Managing stress alongside other triggers helps reduce recurrence.

What does an adult ear infection look like?

Adult ear infections often produce visible redness, swelling, and drainage in outer ear cases.

Middle ear infections aren’t visible externally but can produce a bulging or red eardrum that a provider sees with an otoscope.

Can adults get swimmer’s ear?

Yes. Swimmer’s ear (outer ear infection) is actually more common in adults than middle ear infections.

Frequent water exposure, humidity, and use of earbuds or hearing aids all increase risk.

Can an ear infection cause vertigo in adults?

Yes. Inner ear infections (labyrinthitis) commonly cause vertigo, nausea, and balance problems.

Severe vertigo with an ear infection deserves prompt evaluation to identify the source and rule out complications.

What is the difference between an ear infection and earwax buildup?

Earwax buildup produces a feeling of fullness, mild hearing changes, and sometimes itching without pain, fever, or drainage.

An ear infection typically produces pain, warmth, and often drainage or systemic symptoms like fever.
