Earwax Build-Up vs Ear Infection: How to Tell the Difference

A blocked or muffled sensation in the ear can be extremely uncomfortable. But is it earwax or something more serious? Earwax build-up and ear infection may present with similar symptoms, making differentiation challenging without clinical assessment.

The treatment for earwax is completely different from the treatment for an ear infection. 

This article outlines the features of both conditions, including key differentiating symptoms, tells you when to sort it yourself and when to get it checked.

Quick Summary:

• Earwax build-up causes gradual blocked/muffled hearing, tinnitus, or mild discomfort, usually without pain, fever, or discharge.
• Ear infection typically presents with ear pain, possible discharge, acute onset, and may include fever or systemic symptoms.
• Pain, discharge, or systemic illness suggests infection; isolated blockage suggests earwax. Clinical assessment is recommended if features are unclear or concerning. 

What Is Earwax Build-Up?

Earwax, known clinically as cerumen, is produced by glands inside the ear canal. It is not dirt. It protects the ear by trapping dust, bacteria, and dead skin cells before they reach the eardrum.

In most people, earwax moves out of the ear on its own. The problem starts when production outpaces natural clearing, or when something pushes the wax deeper into the canal. Cotton buds are the most common culprit.

Build-up is especially common in people who use hearing aids, earphones, or ear defenders regularly. Older adults and those with naturally narrow or hairy ear canals are also more prone to blockages.

Symptoms of Earwax Build-Up

• A feeling of fullness or pressure in the ear
• Muffled or reduced hearing, often described as hearing through cotton wool
• Mild earache or a dull ache rather than sharp pain
• Tinnitus, which is a ringing, buzzing, or humming sound
• Itchiness inside the ear canal
• Occasional dizziness, particularly if the blockage is significant

The key thing to note: initially there is usually no discharge, fever, or sharp pain. 

What Is an Ear Infection?

An ear infection is caused by bacteria or a virus getting into part of the ear. There are two main types: 

1. Outer ear infections (otitis externa) 
2. Middle ear infections (otitis media)

Otitis externa affects the ear canal itself. It is sometimes called swimmer’s ear and is linked to moisture, scratching, or skin conditions like eczema. Otitis media affects the space behind the eardrum and is more common in children, though adults get it too, often following a cold or flu.

Both types need a different approach to earwax.

Symptoms of an Ear Infection

• Sharp or throbbing pain inside the ear
• Discharge from the ear, which may be yellow, green, or blood-tinged
• The ear canal or surrounding area may feel tender to touch
• Fever, particularly in children
• Reduced hearing alongside pain rather than on its own
• Feeling generally unwell or run-down
• Itching with redness and swelling (more typical of outer ear infections)

With an ear infection, symptoms come on faster. Pain is often the first and most prominent feature.

Earwax Build-Up vs. Ear Infection: Key Differences

These two conditions can overlap in how they feel, which is why people confuse them. But there are clear distinctions once you know what to look for.

The clearest signals: if you have discharge and fever alongside ear pain, it points strongly toward infection. If your main complaint is a blocked, muffled ear without pain or systemic symptoms, earwax is the more likely cause.

It is worth mentioning that earwax build-up after an ear infection does occur. If your ear still feels blocked once an infection has cleared, residual wax may be the reason.

Key Causes and Risk Factors

Understanding what leads to each condition can help you avoid both.

Earwax build-up is more likely if you:

• Use cotton buds or push anything into the ear canal
• Wear hearing aids, earbuds, or custom ear protection regularly
• Have naturally narrow or very hairy ear canals
• Are older, as earwax tends to become drier and harder to shift with age
• Produce more wax than average (some people simply do)

Ear infections are more likely if you:

• Have recently had a cold, flu, or upper respiratory infection
• Swim regularly, particularly in pools or open water
• Have a skin condition affecting the ear canal, such as eczema or psoriasis
• Use cotton buds or fingernails to scratch inside the ear
• Have a weakened immune system or diabetes

There is a crossover here. Scratching the ear canal trying to remove wax can introduce bacteria and trigger an outer ear infection. This is one of the main reasons self-treatment with cotton buds carries real risk.

Treatment Options

If You Suspect Earwax Build-Up

Softening drops such as olive oil or sodium bicarbonate may be used to help manage earwax build-up where appropriate, in line with UK primary care guidance. Apply a few drops into the affected ear two to three times daily for five to seven days.

Sodium bicarbonate drops are an alternative if you find olive oil too greasy. Both work by softening the wax so it can move out naturally or become easier to remove professionally. Do not use cotton buds or ear candles. 

If drops do not clear the blockage, then book an appointment for professional earwax removal. The two main methods used in clinical settings are:

1. Microsuction: A gentle suction device removes wax under magnification. It is safe, quick, and suitable for most people.
2. Irrigation: A controlled stream of water flushes the wax out. Not suitable if you have a perforated eardrum or a history of ear surgery.

If You Suspect an Ear Infection

Some mild ear infections, particularly viral or uncomplicated cases, may resolve within one to two weeks, while others (such as otitis externa) may require topical treatment. 

For outer ear infections, a pharmacist can often recommend antibiotic ear drops without you needing to see a GP first. Middle ear infections with significant pain, discharge, or symptoms lasting more than a few days usually warrant a GP review.

Children under two with ear infections should always be seen by a doctor promptly. Do not attempt to irrigate or remove earwax while an active infection is present. This can push bacteria further into the ear and worsen the situation.

Prevention Tips for Earwax Build-Up and Ear Infections

A few simple habits reduce your risk of both conditions.

For earwax:

• Ears are self-cleaning and do not need you to intervene.
• If you use hearing aids or earphones, clean them regularly and take breaks from wearing them.
• Olive oil drops may be used intermittently in individuals with recurrent wax build-up if advised by a healthcare professional.
• Book periodic professional removal if you have a history of impaction.

For ear infections:

• Dry your ears thoroughly after swimming or bathing. Tip your head to each side and let gravity help.
• Avoid submerging your head in untreated or stagnant water.
• Do not scratch inside the ear canal with fingernails or cotton buds.
• Treat eczema or other skin conditions on the outer ear promptly to reduce the chance of canal involvement.
• Keep up to date with flu vaccination, as flu is a common trigger for middle ear infections.

When to See a Specialist?

Most ear problems can be handled at a GP surgery, pharmacist, or ear care clinic. But there are situations where you should not wait.

Seek prompt medical attention if you notice:

• Sudden or severe hearing loss
• Discharge that is bloody or has a foul smell
• Significant pain that does not respond to over-the-counter pain relief
• Symptoms lasting more than two to three weeks without improvement
• Dizziness, loss of balance, or a spinning sensation (vertigo)
• Facial weakness or drooping alongside ear symptoms
• High fever with ear pain in a child under two

Your pharmacist is often the quickest first port of call. Under Pharmacy First, pharmacists in England can assess, diagnose, and treat ear infections without a GP appointment. For earwax, many pharmacies offer microsuction directly.

If your GP suspects a more complex infection, a perforated eardrum, or a recurrent problem, they may refer you to an ENT specialist for further assessment.

FAQs

Can you have both earwax build-up and an ear infection at the same time?

Yes, and it is more common than people realise. Excessive wax can trap moisture and bacteria inside the ear canal, creating conditions where an infection takes hold. Equally, as mentioned earlier, the inflammation caused by an ear infection can impair normal wax migration. See a professional rather than attempting home treatment for wax alone.

Is it safe to use ear drops if I think I might have a perforated eardrum?

Not all ear drops are safe with a perforated eardrum. Olive oil drops are generally considered low risk, but many medicated ear drops, particularly those containing aminoglycoside antibiotics, carry a warning against use with perforation. If your eardrum has a hole in it, get a clinical assessment before using anything. 

My child keeps pulling at their ear but has no fever. Is it an infection?

Not necessarily. Ear pulling in babies and toddlers can mean anything from teething discomfort to simple curiosity. A fever, irritability, sleep disruption, and reduced appetite together with ear pulling are more suggestive of infection. Without fever and with an otherwise well child, it may be worth monitoring for 24 to 48 hours.

Can earwax cause tinnitus?

Yes. Impacted earwax pressing against the eardrum can produce a ringing, buzzing, or humming sensation in the ear. This type of tinnitus usually resolves once the wax is removed. If tinnitus persists after professional earwax removal, it should be investigated further, as there may be an underlying cause unrelated to wax. 

How do I know if my ear has fully cleared after treatment?

After professional earwax removal, a practitioner will usually confirm the canal is clear using an otoscope. If you had drops at home and your hearing has improved, the fullness sensation has gone, and your symptoms have resolved, the wax has likely shifted. Residual wax fragments can sometimes remain after irrigation and may need a follow-up appointment.

Conclusion

Earwax build-up and ear infections share symptoms but require different treatments. Correctly identifying the issue saves time and prevents wrong treatment.

If your ear feels blocked and muffled without pain, discharge, or fever, earwax is likely present. If you have pain, discharge, or feel unwell, an infection is probable, consult a pharmacist or GP.

If you have a blocked ear or suspect a

n infection, reach out to a pharmacist or GP for assessment and management as appropriate.
