You've had a blocked nose for two days, and now one ear has joined in. It feels full, sounds are muffled, and there's a dull ache that sharpens when you swallow. Ear pain due to cold is one of the most miserable parts of an ordinary cold, partly because it arrives late, when you thought the worst was over.
Here's the thing almost every article on this gets wrong: the pain isn't really coming from the part of your ear you can reach. It's coming from behind the eardrum — and the reason it's there at all is your nose.
That single fact changes what you should do about it. It also explains why the most popular home remedy in India for this problem is the one you should skip.
Why a cold makes your ear hurt
Your middle ear — the small air-filled space just behind the eardrum — is sealed off from the outside world. The eardrum is a wall. Nothing gets past it.
But that space still needs air, and it gets it through a narrow passage called the Eustachian tube, which runs from the middle ear down to the back of your nose. That tube is normally shut, and it flicks open for a moment every time you swallow, yawn or chew, topping the air up and keeping the pressure balanced. You've felt it working every time your ears popped on a flight or on a hill road.
A cold swells the lining of your nose and throat. That swelling reaches the opening of the Eustachian tube and closes it. And once the tube stops opening:
- the air already sealed in the middle ear is slowly absorbed by the surrounding tissue;
- the pressure in there drops below the pressure outside;
- the eardrum gets pulled inwards by the difference.
That's the ache. That's the fullness, the muffled hearing, the crackle and pop when you swallow. Fluid can also collect in the space behind the eardrum, which is why the muffled feeling sometimes outlasts the cold by a good while.
So the honest summary is this: your ear hurts because your nose is blocked. The ear end is where you feel it. The nose end is where the problem is.
Why you shouldn't put oil, garlic or drops in your ear
Search for this in India and you'll be told, over and over, to warm some sesame oil with garlic or ajwain and put a few drops into the sore ear. It's an old, well-meant remedy, and the instinct behind it is genuinely right: warmth is soothing for an aching ear.
The location is wrong, and it matters for two reasons.
First, it can't reach the problem. The pain is behind the eardrum. The eardrum is a sealed wall. Anything you pour into the ear canal sits on the outside of that wall and goes no further. It cannot touch the trapped pressure, because the trapped pressure isn't on that side.
Second, and more importantly, you can't see your own eardrum. A middle-ear infection can perforate it, sometimes with very little warning beyond the pain suddenly easing. If there's a hole and you put oil into the canal, that oil now has a route into the middle ear, which is not a place for it. This is precisely why ENT guidance is consistent that drops of any kind shouldn't go into an ear that hasn't been looked at, and why fluid or discharge coming out of an ear is a reason to see a doctor rather than to put something in.
The safe version of the same instinct: hold a warm compress against the outside of the ear. A cloth wrung out in warm water, or a covered hot-water bottle, resting against the ear and the side of the jaw. You get all of the comfort and none of the risk. It's the same remedy with the geography corrected.
When it's your ear and when it's actually your throat
Ear and throat pain turning up together confuses a lot of people, and there's a neat piece of anatomy behind it. Your throat and your ear share some of the same nerve supply, so pain that starts in an inflamed throat is often felt in the ear. The ear itself can be perfectly fine.
The everyday tell is swallowing. If the pain spikes sharply each time you swallow and your throat is raw, you're most likely dealing with a throat problem that's being referred upwards — worth reading our guide to home remedies for a sore throat, or, if it's severe and lingering, throat infection home remedies.
If instead the ear feels full and underwater, sounds are muffled, and swallowing gives you a pop or a click rather than a stab, that's the Eustachian tube story above — and the nose is where to aim.
Plenty of colds serve both at once, in which case treat both and don't overthink which came first.
What actually helps
Nearly all of this works at the nose end, because that's where the blockage is.
Clear the nose, gently and often. This is the whole game. A blocked nose keeps the Eustachian tube shut; a clearer nose lets it start opening again. Our guide to clearing a blocked nose naturally covers the practical options and the correct spray technique, which is worth getting right.
Swallow, yawn and chew — deliberately. The tube opens on those movements, so give it more chances. Sipping water through the day, chewing something, or a big deliberate yawn will often produce a pop and a moment of relief. It's the simplest thing on this list and the most underused.
Equalise gently, if at all. Pinching your nose and blowing softly against it can nudge air up the tube. Keep it gentle — a hard, forceful blow can do more harm than good, and if it hurts, stop. Skip it entirely if you have any discharge from the ear.
Sleep propped up. An extra pillow, and the sore ear facing upwards if only one side is affected. Elevation helps things drain rather than pool overnight, which is when this usually feels worst.
Warm compress on the outside. As above. Comforting, safe, and it works on the jaw ache that often comes with it.
Keep fluids up. Warm drinks are pleasant and hydration keeps mucus thinner and more mobile. Our home remedies for cold and cough guide has the rest of the routine.
What we'd leave off the list: reaching straight for a strong decongestant spray. Those have their own trade-offs — including rebound congestion if they're used for more than a few days — and that's covered honestly in the blocked-nose guide above.
How long does it last?
For most colds, the fullness and ache ease within a few days to a week or so, roughly tracking the nose.
The muffled, underwater feeling can outstay its welcome, though. When fluid is left sitting behind the eardrum after the cold has gone, hearing can stay slightly dulled for several weeks. Mild Eustachian tube dysfunction commonly settles on its own over a period of weeks rather than days, so a bit of patience is normal and not a sign that something is wrong.
What isn't normal is worsening. Pain that climbs rather than fades, or that arrives with a fever, deserves a look rather than more waiting.
When to see a doctor
Please don't self-manage any of the following — get it looked at:
- Severe or rapidly worsening ear pain, or pain that hasn't started to settle after a few days.
- Any discharge or fluid coming from the ear, or bleeding.
- Noticeable hearing loss, or hearing that stays dulled for more than a few weeks after the cold.
- High fever, or feeling genuinely unwell rather than cold-unwell.
- Dizziness or a spinning sensation.
- A child with ear pain. Middle-ear infections are common in children with colds and are properly assessed by a doctor, not at home.
- Symptoms dragging past about twelve weeks, which is the point at which persistent Eustachian tube trouble is worth investigating.
Where ErasaVir fits — and where it doesn't
Let's be straightforward about this, because it's an ear article and we make a nasal spray.
ErasaVir is not eardrops. It never goes in your ear. It doesn't treat an ear infection, it doesn't act on your ear, and nothing sprayed into your nose is a treatment for ear pain. If your ear is the problem, the list above and, where it applies, a doctor are the answer.
What ErasaVir's nasal spray is for is the nasal congestion that sits upstream of all this. It's a plant-based, alcohol-free spray built around an extract of safflower, and in a randomised clinical study the range eased nasal congestion and other cold symptoms as well as a conventional treatment regimen (antibiotics, an antihistamine and paracetamol), drug-free. That's the measured claim, and it's the only one we'll make here.
If a raw throat is the half you're feeling in your ear, the mouth and throat spray is the companion piece — see our guide to a throat spray for pain relief.
And in the same spirit as washing your hands, keeping the nose and throat clean is a small daily respiratory-hygiene habit rather than something to start only once a cold has taken hold. It's upkeep, not a shield — but it's a sensible step through the cold months.
Ear pain due to cold: frequently asked questions
Can a cold cause ear pain?
Yes, and commonly. A cold swells the lining at the back of the nose and closes the Eustachian tube that ventilates the middle ear, so pressure behind the eardrum drops and the eardrum is pulled inwards. That's the ache and the blocked feeling.
Why does my ear pain during a cold get worse at night?
Lying flat lets congestion and fluid settle rather than drain, and there's less to distract you from it. Propping your head up on an extra pillow, with the sore ear facing upwards, usually helps.
How can I reduce ear pain due to cold at home?
Work at the nose rather than the ear: keep the nose as clear as you can, swallow, yawn and chew to open the tube, sleep propped up, and hold a warm compress against the outside of the ear. See a doctor for severe pain, discharge, fever, or if it's a child.
Can I put oil or ear drops in for ear pain from a cold?
Best not to. Nothing in the ear canal can reach the middle ear, where the problem is, and if the eardrum is perforated — which you can't check yourself — drops or oil can get somewhere they shouldn't. A warm compress on the outside gives you the same comfort safely.
Is ear pain when swallowing coming from my ear or my throat?
Often the throat. The throat and ear share nerve supply, so throat inflammation is frequently felt in the ear. A sharp stab on each swallow with a raw throat points at the throat; a full, muffled, popping ear points at the Eustachian tube.
How long does ear blockage after a cold last?
The ache usually eases within a few days to a week, along with the nose. Muffled hearing from fluid behind the eardrum can linger for several weeks, which is common and usually settles by itself. Get it checked if hearing stays dulled or anything worsens.
Does a blocked ear from a cold mean I have an ear infection?
Not necessarily — most is simple pressure from a closed Eustachian tube. An infection is more likely with severe pain, fever, feeling properly unwell, or discharge from the ear, and those are reasons to see a doctor.
The bottom line
Ear pain with a cold is a nose problem being felt in the ear. The middle ear is sealed behind the eardrum and ventilated by a tube that opens at the back of the nose, and a cold swells that tube shut.
So work at the nose, swallow and yawn to nudge the tube open, sleep propped up, and put the warmth on the outside of the ear rather than inside it. Give it a few days to follow the cold out. And take severe pain, discharge, fever, dizziness or a child's earache to a doctor rather than to a home remedy.
