Blocked ear: is it wax, or is it an infection?
Last updated September 3, 2026.
A blocked, muffled ear has two common culprits that need opposite handling: impacted earwax (harmless, fixable with drops) and ear infection (inflamed, painful, sometimes needing treatment). The sorting matters because poking at either makes things worse, and the number-one rule covers both: nothing goes in the ear, ever, especially not cotton buds.
Which one is it?
Wax: gradual muffled hearing, fullness, sometimes ringing, itch, or a cough (the ear canal tickles a shared nerve), usually painless or mildly achy, often after bud use (which rams wax deeper) or earplug and hearing-aid wear. Infection: pain is the headline, often with a cold in progress, fever (especially in children), discharge if the drum gives way, and tenderness. The canal version (otitis externa, swimmer's ear) hurts when the outer ear is tugged and itches fiercely. Painless muffling leans wax; painful leans infection.
Why does wax build up?
Wax is a feature, not dirt: it cleans, lubricates, and protects the canal, and normally migrates out on its own. Impaction happens when the self-cleaning fails: narrow or hairy canals, age (drier wax), earplugs, hearing aids, and, above all, cotton buds, which remove a little wax from view while pushing the rest against the drum as a plug. The ear is self-cleaning; the bud is the problem pretending to be the solution.
What actually helps?
- Wax first-line: drops, not tools: olive or almond oil drops (or pharmacy sodium bicarbonate or peroxide drops) for 3-5 days soften the plug so it migrates out; a temporary increase in blockage feeling is normal as the wax swells.
- Never insert anything: no cotton buds, hairpins, keys, or ear candles (candles are both useless and a burn-and-perforation hazard, with no evidence behind them).
- If drops fail: professional removal (microsuction or irrigation) is quick and safe; irrigation is avoided with a known perforated drum or previous ear surgery.
- Infection first-line: pain relief and time: most ear infections are viral and self-limiting over about 3 days; paracetamol or ibuprofen, warmth against the ear, and no water in the canal.
- Antibiotics selectively: for severe, persistent (3+ days), bilateral, discharging, or very young cases, at a clinician's judgment; most ear infections never need them.
When is it an emergency?
Most ear trouble is routine. Same-day or urgent care for: a child (especially under two) with severe ear pain, high fever, or both ears infected; swelling, redness, or tenderness behind the ear, or the ear sticking out (possible mastoiditis); facial weakness on that side; severe dizziness with the ear pain; discharge that is bloody; sudden complete hearing loss in one ear (a different emergency: same-day); and pain with a stiff neck, severe headache, or confusion.

Common questions
Why are cotton buds so bad if they come out with wax on them?
Because the visible bit on the bud is the trap's bait: the bud skims a little wax from the outer canal while its tip rams the deeper wax onward, compacting it against the eardrum into a plug. Meanwhile it scratches the canal skin (itching, and an entry for swimmer's-ear infections), and in the worst cases it reaches the drum itself. The canal is self-cleaning: jaw movement walks the wax out on its own, and shower water at the entrance plus a towel on the outer ear is all the maintenance a normal ear needs. The ear care rule is old and absolute: nothing smaller than your elbow goes in your ear.
Do ear candles work?
No, and they are genuinely dangerous: studies show the residue inside the candle afterwards is candle wax, not earwax (the suction claim is physically false, tested and debunked), while the documented harms include burns to the face and ear, candle wax dripped into the canal, and eardrum perforation. Every major hearing and ear body advises against them. The safe route is boring and effective: softening drops for a few days, then professional microsuction or irrigation if the plug persists. There is no shortcut through an open flame held to your head.
How do I use ear drops properly?
Warm the bottle in your hand (cold drops cause dizziness), lie with the problem ear up, instill the drops (usually 2-3, two or three times daily), and stay lying for 5-10 minutes so they soak in rather than running out. Expect the blockage to feel worse for a day or two as the wax swells before it softens, and give the course 3-5 days. Oil drops (olive or almond) are the gentle first choice; peroxide or sodium bicarbonate drops work faster but irritate some canals. Skip drops entirely and get looked at first if you have a known perforated drum, grommets, previous ear surgery, or an active infection.
My child has ear pain. Infection or wax, and does it need antibiotics?
In a child, painful ear with a cold or fever is infection (otitis media) far more often than wax, and the routine surprises most parents: the great majority are viral, peak within a day or two, and resolve within about three days with pain relief alone, no antibiotics required. Antibiotics enter for severe cases, both ears, discharge, symptoms beyond three days, and the under-twos, at a clinician's call. Wax in children presents the adult way (painless muffling), is common with bud use on small canals, and is treated with drops or professional removal, never poking.
The blockage cleared but my ear still feels off. Normal?
A day or two of oddness after a plug comes out is common: the canal skin is sensitive after being stretched, sounds can seem strangely loud or hollow (the ear readjusts), and there may be mild itch. Settle signs: hearing normalizing day by day and no pain. The patterns that mean get it checked: pain appearing or worsening, any discharge, ringing that persists or is one-sided, hearing that stays down a week after clearance (could be residual wax, fluid behind the drum, or something needing a hearing test), and dizziness, which the ear should not cause once clear.
Can earwax cause dizziness or a cough?
It can, through anatomy: the canal shares a nerve branch with the throat, so a wax plug (like a stray hair or a bud) can trigger a dry tickly cough that vanishes when the ear is cleared, a recognized oddity with a nerve explanation. Dizziness is rarer but real when wax presses on the eardrum, though persistent true dizziness should not be assumed to be wax: if clearing the ear does not end the spinning, it needs its own assessment. The same nerve-sharing quirk is why ear problems sometimes present as a throat tickle or cough with a completely normal throat examination.
