The clearest signs you need professional ear wax removal are muffled or reduced hearing, a feeling of fullness or pressure in the ear, ringing or buzzing (tinnitus), itching or discomfort, mild dizziness, and any change in how your hearing aids are performing. If you’ve experienced any of these for more than a few days, especially after trying olive oil drops, it’s time to book a microsuction appointment.
I’m Ish, an HCPC-registered audiologist running the wax removal clinic at Hear With Ish, based in Leicester. Patients ask me daily whether their symptoms really mean wax, or whether something else is going on. The honest answer is that wax build-up has a fairly recognisable pattern, and once you know what to look for, you can usually tell it apart from infections or hearing loss.
Ear wax is normal, healthy, and useful. Your ears produce it to trap dust, repel water, and protect the delicate skin of the ear canal, which is why the NHS advice on earwax build-up is generally to leave it alone unless it causes symptoms. Most of the time, the system works without you ever noticing. The seven signs below are the points where it’s stopped working and needs help.
1. Muffled or Reduced Hearing
This is the most common sign. People often describe it as feeling like one ear is underwater, or as if there’s cotton wool stuffed in the canal. It usually comes on gradually, then suddenly feels much worse after a shower, a swim, or a humid day, because water has caused the wax plug to swell and seal the canal.
The hearing loss is reversible. Once the wax is removed, your hearing should return to normal almost immediately. If it doesn’t, that suggests an underlying issue and a hearing assessment is the next step.
Worth saying: a sudden, severe drop in hearing in one ear that comes on within hours is not usually wax. That’s a medical urgency and warrants a call to NHS 111 or your GP the same day.
2. A Sense of Fullness or Pressure
Many patients describe a feeling like their ears need to pop but never quite do. It’s the same sensation you get on a plane during descent, except it doesn’t go away. This is usually wax pressing against the eardrum or sealing the canal.
Pressure on its own is rarely an emergency, but it does tend to get worse rather than better, because the wax continues to build up while you’re waiting it out. Treating it earlier means a faster, more comfortable appointment.
3. Tinnitus or Ringing in the Ears
Tinnitus has many causes, but ear wax is one of the easiest to treat. When wax presses against the eardrum, it can create a buzzing, ringing, or hissing sound that disappears the moment the wax is cleared.
If your tinnitus persists after wax removal, that’s worth investigating further. We have a tinnitus management service for patients whose tinnitus has other underlying causes, and the British Tinnitus Association offers excellent self-help guidance for the meantime.
Tinnitus from wax usually affects one ear more than the other, and tends to be a relatively constant tone that changes when you swallow or yawn. Tinnitus from inner-ear hearing loss tends to affect both ears equally and doesn’t shift with movement.
4. Earache or Discomfort
Wax doesn’t usually hurt by itself, but a large impacted plug can press against the canal walls and cause a dull ache. If the discomfort is sharp or throbbing, that’s more likely an infection and should be assessed before any wax removal is attempted.
True earache, the kind that wakes you at night or makes one side of your face feel hot, is more often a middle-ear infection than wax. See your GP first if pain is severe.
5. Itchy Ears
Persistent itching deep in the ear can be a sign of dry, flaky wax that’s irritating the canal. Resist the urge to scratch with a cotton bud, that’s how most damage to the ear canal happens. A professional can clear the wax safely and check for any underlying skin problem.
Itching can also be caused by eczema, fungal infection, or sensitivity to a hearing aid dome material. We’ll usually be able to tell the difference during the examination.
6. Dizziness or Balance Issues
This one surprises people. The inner ear controls balance as well as hearing, and a heavy wax plug can occasionally affect the way the eardrum moves, leading to mild dizziness. It’s usually mild and intermittent.
Severe or sudden dizziness needs urgent medical attention, it’s not just wax. Spinning room sensations, vomiting, or loss of balance all warrant an immediate call to your GP or NHS 111.
7. Hearing Aids Whistling or Sounding Wrong
If you wear hearing aids and they’ve started whistling, distorting, or sounding muffled, ear wax is the most likely cause. Wax interferes with the seal between the dome or mould and the canal, and it can clog the receivers themselves. There’s a more detailed guide to ear wax removal for hearing aid wearers covering the trouble-shooting steps.
Hearing aid wearers usually need wax management more frequently than other patients, every six to twelve months on average, because the device itself blocks normal wax migration. Left untreated, the build-up can damage the receivers and shorten the working life of the aid.
If your aids have stopped working entirely, that’s not always wax, and a quick visit to our hearing aid repairs service can usually identify the issue.
When to See a GP Instead
Most of the symptoms above can be handled by a private audiologist. But you should see a GP first if you have severe pain, discharge from the ear, sudden hearing loss, fever, or a history of recent ear surgery. These can suggest infection, perforation, or other conditions that need medical assessment before wax removal is safe.
Children under six, or anyone who can’t sit still for examination, should generally see their GP first. There’s also broader patient guidance on the RNID earwax page covering self-help and when to escalate.
What Not to Do
Don’t use cotton buds, hairpins, ear candles, or anything else inserted into the canal. These cause more problems than they solve. If you want to soften wax at home, use plain olive oil drops or a pharmacy product designed for ears, nothing else.
Don’t ignore symptoms hoping they’ll go away. Mild wax build-up usually doesn’t resolve on its own, particularly in older adults and hearing aid wearers. The longer you wait, the harder the wax becomes and the longer the appointment takes.
Don’t try home suction kits sold online. The pressure isn’t controlled, the tips are too long, and the risk of perforation or canal damage is real.
Booking Your Appointment
When you’re ready, book an appointment through the ear wax removal page or call the clinic. Most patients are seen within the same week, and urgent cases, severe pain, complete blockage, can usually be fitted in within 24 hours.
How Long to Wait Before Booking
If your symptoms are mild, blocked feeling, slight muffling, occasional itching, the right first step is two or three days of olive oil drops. About half of mild cases resolve within a week without any professional intervention.
If symptoms haven’t improved within a week of consistent drop use, or if they’re getting worse, that’s the point to book. Waiting longer rarely helps and usually means a more impacted plug by the time you’re seen, which adds time and discomfort to the appointment.
Severe symptoms, sudden hearing loss in one ear, significant pain, discharge, fever, are not ‘wait and see’ cases. See your GP or NHS 111 the same day. These can suggest infection, perforation, or other conditions where wax removal isn’t the appropriate first treatment.
Hearing aid wearers should book sooner rather than later because wax against the device shortens its working life. If your aid is sounding wrong, the longer you leave it, the more risk of damage to the receivers. The hearing aid repairs and servicing can usually combine wax removal and aid servicing in a single appointment.
How We Diagnose What’s Actually Going On
When you come in, the examination uses a video otoscope so we can both see what’s happening in the canal. The image is projected on a screen, which means you’re not relying on someone else’s verbal description. If wax is the issue, you’ll see it. If something else is going on, you’ll see that too.
We can usually distinguish wax from fluid behind the eardrum, from outer ear infection, from foreign bodies, and from skin conditions within the first minute of examination. That diagnostic clarity is one of the genuine advantages of microsuction practices, the routine investment in good imaging equipment isn’t matched by all providers.
If we find something outside our scope, ENT-level concerns, complex chronic infection, suspected cholesteatoma, we’ll explain what we’re seeing and recommend the right onward referral. We’re not trying to treat everything; we’re trying to make sure you end up with the right person.
What to Bring to Your Appointment
There’s not much to prepare. Bring a list of any medications you take, particularly blood thinners, and any history of ear surgery or hearing aids you currently wear. If you’ve used softening drops in the days before, mention what brand and how often.
If you’ve been getting recurring infections or have any history of skin conditions affecting the canal, that’s worth flagging too. The information shapes the safest approach during the examination, and there are no awkward questions, just practical ones that help us deliver the right care.
Frequently Asked Questions
How quickly can wax build up?
It varies. Some people produce noticeable amounts within weeks; others go years between needing professional removal. If you wear hearing aids or have narrow canals, expect more frequent build-up.
Can wax cause permanent hearing loss?
Wax itself doesn’t cause permanent damage, but the temporary hearing loss can be significant. If the wax is left for a very long time, it can occasionally lead to skin issues in the canal that need additional treatment.
Should I try drops first?
Yes, two to three days of olive oil or pharmacy ear drops can soften wax considerably and sometimes resolve mild blockages. If symptoms persist, book an appointment.
Is itchy ear always wax?
Not always. It can also be due to dry skin, eczema, or fungal infection. An audiologist can usually tell the difference during examination.
How do I know if it’s wax or something more serious?
If you have any pain, discharge, fever, or sudden hearing change, see your GP first. Otherwise, an audiologist examination will quickly tell you what’s going on.
Can I just keep using olive oil indefinitely?
Olive oil is fine as a maintenance routine, two or three drops once a week, but it’s not a substitute for professional removal once a plug has formed. Once symptoms appear, drops alone usually aren’t enough.
Will wax removal help my tinnitus?
If wax is the cause, yes, the tinnitus usually disappears immediately. If tinnitus persists after wax removal, other causes need exploring.
