Suddenly Lost Hearing in One Ear? Don’t Wait.
You woke up and one ear sounds dull or blocked. Or the phone suddenly went quiet on one side. It’s tempting to assume it’s wax or a cold and give it a few days. Sometimes it is. But sudden hearing loss can also be a medical emergency, where treatment works best when it starts early. This page explains why, and what to do today.
Go to a hospital emergency department now if
- The hearing loss comes with a drooping face, weakness or numbness in an arm or leg, slurred speech or confusion.
- You have severe dizziness and can’t walk or stand, a severe headache, or double vision.
- The hearing loss followed a head injury.
Together with sudden hearing loss, these can be signs of a stroke or another serious problem. Don’t wait for a clinic appointment.
Sound familiar?
How sudden hearing loss often begins
- “I woke up and my right ear felt stuffed, like it was full of water.”
- “I picked up a call and realised I couldn’t hear anything on my left side.”
- “There was a pop, then a loud ringing, and now the ear sounds muffled.”
- “I thought it was a cold, so I waited a week, but it hasn’t come back.”
- “Along with the dull ear, the room spun for a while and I felt unsteady.”
Any of these, happening over hours or up to about three days, is worth acting on today. Waiting to “see if it clears” is the most common and most costly mistake.
What’s happening
What sudden hearing loss can mean
A sudden drop in hearing has two very different kinds of cause, and they feel almost the same from the inside.
A blockage or middle-ear problem. Earwax pressed against the eardrum, fluid behind the eardrum after a cold, or a blocked Eustachian tube can all make an ear feel dull quite suddenly. These are usually very treatable and not dangerous.
A problem in the inner ear or hearing nerve. Doctors call this sudden sensorineural hearing loss. It usually affects one ear, is often noticed on waking, and may come with ringing, a feeling of fullness or dizziness. In many cases no single cause is found, although viral infections and problems with blood flow to the inner ear are among the suspected triggers. This is the kind that needs medical treatment quickly.
Here is the difficulty: you can’t reliably tell the two apart yourself. A “blocked” feeling is common to both. Many people with inner-ear sudden hearing loss first assume it is wax, try ear drops or cotton buds, and lose valuable days. A doctor’s examination and a hearing test can separate them quickly.
Why the rush? When sudden sensorineural hearing loss is treated, usually with medicine prescribed by a doctor or ENT specialist, treatment is generally more effective the earlier it starts. Some people recover part or all of their hearing, and some don’t, and nobody can predict which in advance. Acting within days, not weeks, gives you the best chance.
Can I tell at home?
Blocked ear or sudden hearing loss?
These are general patterns, not a way to diagnose yourself. Treat any sudden change as urgent until a professional has checked it.
| Sign | More typical of a blockage or middle-ear cause | More typical of sudden sensorineural loss |
|---|---|---|
| How it started | After a cold, flight, swimming or cleaning the ears | Often on waking, or with no obvious trigger |
| Other symptoms | Ear pain, pressure that changes when you swallow or yawn | New ringing, fullness, and sometimes dizziness |
| Your own voice | Often sounds louder or echoey in the blocked ear | Usually doesn’t sound louder in the affected ear |
| What helps | Treating the wax, fluid or infection, as advised by a doctor | Prompt medical treatment, ideally started as soon as possible |
Please don’t put cotton buds, oil or drops into the ear before it has been examined. If the eardrum is damaged, that can make things worse.
What to do today
The tests that help your doctor decide
Your first call should be to a doctor or ENT specialist, or to us, today. A hearing test is quick and painless, and its results help the doctor choose the right treatment.
Ear examination
Video otoscopy shows straight away whether wax, fluid or a damaged eardrum is behind the sudden change.
Tympanometry
Checks eardrum movement and middle-ear pressure. A normal result points away from a simple blockage.
Pure-tone audiometry (PTA)
Measures how much hearing has changed in each ear and whether it is an inner-ear loss. It also gives a starting point to track recovery.
If our results suggest sudden sensorineural loss, we’ll tell you clearly and point you to an ENT specialist without delay, with your audiogram in hand. If you’re dizzy as well, we can also discuss balance testing once you’ve been seen medically.
Afterwards
If hearing doesn’t fully return
This page doesn’t recommend a hearing aid, and that’s deliberate. In the first days and weeks, the priority is medical treatment and giving the ear every chance to recover.
Once your doctor is happy that the situation has settled, we’ll repeat your hearing test to see where things stand. If some loss remains, there are good options, from hearing aids suited to hearing loss in one ear to support for any lasting ringing or tinnitus. That conversation comes later, at your pace.
