Blocked ears are one of those things that can creep up gradually or arrive suddenly. Once you notice them, they are difficult to ignore. That muffled, full, slightly pressurised sensation in one or both ears affects a large number of people at some point, and in many cases the cause is something entirely straightforward and treatable.

The most common culprit is ear wax. But blocked ears can also be caused by fluid behind the eardrum, changes in air pressure, sinus congestion, or in less common cases, something that needs a closer look from a professional. Knowing the difference matters, because the right next step depends entirely on what is causing the problem.

This guide explains the main causes of blocked ears, what symptoms to look out for, which home remedies are worth trying and which are best avoided, and when it is sensible to get a professional to take a look. If you are in the North East and the problem turns out to be ear wax, Hear Better can arrange a home appointment for ear wax removal without you needing to travel anywhere.

What causes blocked ears?

Blocked ears do not always have one obvious cause, and the sensation itself, that feeling of fullness, reduced hearing or pressure, can come from several different sources. Understanding which category you are in helps you decide what to do next.

The main causes of blocked ears are: a build-up of ear wax, fluid in the middle ear often following a cold or respiratory illness, pressure differences between the ear and the surrounding environment, sinus congestion or hay fever, a foreign object in the ear canal, and in rarer cases, problems with the eustachian tube or the eardrum itself.

Ear wax is by far the most frequently seen cause in adults, particularly in people who use hearing aids, wear earbuds or earplugs regularly, or tend to produce more wax than average. It is also more common in older adults, as wax tends to become drier and less mobile with age.

Symptoms to be aware of

The symptoms of blocked ears vary depending on the cause, but there are some common patterns worth knowing. The overlap between causes is one of the reasons people sometimes try to manage the problem at home for too long before seeking help.

Symptoms typically associated with ear wax

Ear wax blockage tends to develop gradually. You might notice that one ear feels muffled or sounds are harder to hear, particularly speech in background noise. There may be a sense of fullness or pressure without any pain. Tinnitus, a ringing, buzzing or humming sound, can also occur when wax presses against the eardrum. Some people describe a crackling or rustling sound when they move their jaw.

It is also common for symptoms to worsen after a shower or swim, because water can cause the wax to swell slightly, temporarily making the blockage more pronounced.

Symptoms associated with fluid or pressure

If the blockage follows a cold, flu, or ear infection, fluid in the middle ear is a more likely cause. Symptoms here tend to include a feeling of water moving around in the ear, reduced hearing that may fluctuate, a sensation of pressure, and occasionally mild pain or discomfort. This type of blockage often resolves on its own as the illness clears, but can persist for several weeks in some cases.

Pressure-related blocked ears, the kind you experience on a plane, when driving through hills, or underwater, feel quite different. There is usually a sharp, sudden change in how your ear feels, sometimes accompanied by mild pain, and the blockage often clears with swallowing, yawning, or the Valsalva manoeuvre (gently blowing while pinching the nose).

Symptoms that need prompt attention

Some symptoms alongside blocked ears should prompt medical assessment rather than waiting or assuming wax is responsible. These include significant ear pain, discharge from the ear canal, sudden hearing loss, dizziness or loss of balance, or symptoms following a head injury. NICE guidance for adults with hearing loss explains which symptoms require immediate, urgent or specialist referral.

When ear wax is the cause

Ear wax, or cerumen, to use the clinical term, is a natural substance produced by glands in the outer ear canal. It serves a useful function: trapping dust and debris, keeping the canal lubricated, and providing a degree of antimicrobial protection. Under normal circumstances, wax moves out of the ear gradually as the jaw moves, helped along by the natural shedding of skin cells.

The problem arises when this self-cleaning process does not work efficiently. Wax builds up, hardens, and eventually forms a plug that sits against or near the eardrum. At that point, hearing can become noticeably muffled, and the other symptoms described above may follow.

Several factors make wax build-up more likely. Regular use of earbuds, hearing aids or earplugs can push wax deeper into the canal rather than letting it migrate outward. Some people simply produce more wax than others, or produce wax that is drier and more prone to impaction. Older adults are particularly susceptible for both of these reasons.

The important thing to understand about ear wax blockage is that it is very treatable, but how it is treated matters. Not all methods are safe, and some of the most popular home remedies can cause more harm than good.

Other causes of blocked ears

If ear wax has been ruled out, or if the blocked feeling came on suddenly alongside other symptoms, there are several other causes worth considering.

Eustachian tube dysfunction

The eustachian tube connects the middle ear to the back of the throat and is responsible for regulating pressure. When it does not open and close as it should, often following a cold, sinus infection or hay fever, the result is a persistent blocked or pressurised feeling. This is one of the more common reasons people experience blocked ears without any wax involvement. It usually resolves as the underlying congestion clears, though in some cases treatment from a GP is helpful.

Fluid in the middle ear

Known clinically as otitis media with effusion, or glue ear, this occurs when fluid accumulates behind the eardrum rather than draining as it should. It is most frequently seen in children but does affect adults, particularly after a respiratory illness. The hearing loss it produces can be noticeable, and it is usually temporary, though it can last several weeks.

Swimmer's ear and minor infections

An infection of the outer ear canal, swimmer's ear, or otitis externa, can cause swelling of the canal walls, leading to a blocked sensation. This is typically accompanied by itching, discomfort or mild pain, and sometimes discharge. It tends to respond well to antibiotic ear drops prescribed by a GP, and should not be managed with home ear wax treatments.

Hay fever and sinus congestion

Allergic rhinitis and sinus congestion are overlooked causes of blocked ears, particularly in spring and summer. The inflammation associated with hay fever can affect eustachian tube function and cause a persistent feeling of pressure or fullness. Antihistamines and nasal sprays sometimes help, though it is worth speaking to a pharmacist or GP if symptoms are ongoing.

What not to do when your ears feel blocked

This is worth addressing directly, because some of the most common responses to blocked ears can genuinely cause harm.

Cotton buds are the biggest culprit. Inserting anything into the ear canal, including cotton buds, hairpins, rolled tissue, or any other object, risks pushing wax deeper, scratching the delicate skin of the canal, and in more serious cases, perforating the eardrum. The NHS guidance on earwax build-up advises against putting objects into the ear canal.

Ear candling is widely available and frequently recommended online, but there is no clinical evidence it removes ear wax, and there are documented cases of burns and wax deposits from dripping candle residue. It is not recommended by any professional audiology or ENT body.

Forceful nose-blowing when ears feel blocked and congested can sometimes push bacteria from the nasal passages up the eustachian tube, potentially making things worse rather than better.

If you are not certain what is causing your blocked ears, it is better to have them assessed before attempting any treatment at home. A professional can look inside the canal, identify what is there, and recommend the most appropriate approach.

What actually helps with blocked ears

If you suspect ear wax is the cause, the NHS earwax guidance describes how pharmacy ear drops may be used to soften wax. Ask a pharmacist which product is suitable, and do not use drops if you may have a perforated eardrum unless a clinician has advised you to do so.

If the blockage does not clear with suitable softening drops, or if symptoms are more pronounced, a professional ear assessment is the appropriate next step. NICE recommends electronic irrigation, microsuction or another removal method such as manual removal when used by a trained practitioner with the correct equipment. Suitability depends on the person's symptoms and ear history.

Microsuction keeps the ear dry and is carried out under direct vision, but it is not automatically the right method for every ear. Suitability must be assessed individually, particularly where there is a perforation, previous surgery or active infection. You can read more about the practical differences in our guide to microsuction vs ear syringing.

For blocked ears caused by pressure, such as after flying, gentle swallowing, yawning, or the Valsalva manoeuvre (pinching the nose and blowing gently) usually resolves the issue within a few minutes to a few hours. Decongestant nasal sprays can also help if the pressure is related to congestion.

For congestion-related blockage following a cold or hay fever, antihistamines, decongestants and nasal steroid sprays are the most useful tools, though they address the underlying cause rather than the ear directly. Most cases resolve naturally within two to four weeks.

When to get professional help

Most cases of blocked ears are not serious and resolve with time or simple treatment. But there are situations where it is sensible to get a professional assessment rather than continuing to manage things at home.

You should see a GP or ear care specialist if blocked ears have persisted for more than two to three weeks, if you have significant hearing loss alongside the blockage, if there is pain, discharge, or bleeding from the ear, if you are experiencing dizziness or balance problems, if the blockage came on suddenly, or if you have tried softening drops and the problem has not improved.

Frequently asked questions

How long do blocked ears usually last?

It depends on the cause. Blocked ears from pressure changes such as flying often clear within a few hours. Wax-related blockage can persist for weeks if left untreated, though olive oil drops often help within a few days for mild cases. Fluid from a cold or infection typically resolves within two to four weeks as the illness clears. If the blockage lasts longer than three weeks or is accompanied by other symptoms, it is worth seeking professional advice.

Can blocked ears cause permanent hearing loss?

In the vast majority of cases, no. Blocked ears caused by ear wax, fluid or pressure are associated with temporary, conductive hearing loss, meaning sound is being physically blocked from reaching the eardrum rather than there being any damage to the hearing system itself. Once the blockage is removed or resolves, hearing typically returns to its previous level.

Is it safe to use cotton buds to clear ear wax?

No. Cotton buds are not safe to use inside the ear canal. They tend to push wax deeper rather than removing it, and they carry a real risk of scratching the canal wall or, in worse cases, perforating the eardrum. The NHS advises against inserting anything into the ear canal, including cotton buds.

Do olive oil drops actually work?

For mild wax build-up, yes. Olive oil drops can soften the wax enough that it migrates out naturally over the course of a week or two. They are less effective for significant impaction, and they do not work for blocked ears caused by fluid or pressure. If you have tried drops for a week or more with no improvement, professional removal is likely to be a more efficient solution.

Yes. Hear Better provides professional ear wax removal at home across the North East, including microsuction where it is the appropriate method. A qualified HCPC-registered audiologist will assess your ears and use the most suitable removal technique. You do not need to travel to a clinic or arrange a GP referral.
