Blocked Ears: Causes, Wax Build-Up and When to Get Help
TLDR
A blocked or muffled ear is often linked to earwax build-up. The NHS lists hearing changes, a blocked feeling, earache, tinnitus, and dizziness among symptoms of wax build-up. Softening drops can help some people, but cotton buds and DIY digging are unsafe. If drops do not settle symptoms, or you have pain, discharge, or sudden hearing change, seek clinical assessment. At The Ear Doctor in Marylebone, trained ear care specialists offer microsuction under CQC regulation (Rizq Medical Ltd, Provider ID 1-21752188247). Book an appointment when you need a professional look at the canal.
Why ears feel blocked
Earwax (cerumen) is normal. It protects the outer ear canal. Problems start when wax builds up enough to narrow or seal the canal so sound does not pass well. The NHS notes that some people regularly get blocked ears because they naturally produce more wax.
Not every blocked sensation is wax. Colds, allergies, middle-ear fluid, and eustachian tube issues can also create pressure or muffling. That is why guessing from symptoms alone is unreliable. A trained clinician looking into the canal can tell wax from other findings.
Common causes of wax-related blockage
Several everyday factors raise the chance of a blocked ear from wax:
- Natural production. Some people make more wax or have narrower canals, so build-up returns more often (NHS Inform).
- Cotton buds and objects. Pushing buds, hair grips, or keys into the ear often drives wax deeper rather than removing it. NICE CKS guidance on outer ear care also stresses that cotton buds and similar objects should not be used in the canal.
- Hearing aids and in-ear headphones. Devices that sit in the canal can compact wax over time.
- Water after swimming or showering. Moisture can swell existing wax so a mild build-up suddenly feels fully blocked.
- Age and dry wax. Drier wax may stick rather than migrate out on its own.
Symptoms linked to earwax build-up
According to the NHS earwax build-up page, wax problems may include:
- Hearing loss or muffled sound
- Earache or a feeling that the ear is blocked
- Ringing or buzzing (tinnitus)
- Vertigo (a feeling of dizziness)
Other sources describe fullness, itch, and, less often, discharge or odour when the canal is irritated. Complete plugging of the canal tends to make muffling more obvious.
Red flags: severe pain, fever, foul discharge, sudden one-sided hearing loss, facial weakness, or injury after inserting an object need urgent medical assessment. Do not wait for a routine wax appointment in those cases.
What you can try safely at home
UK self-care advice commonly starts with softening, not digging:
- Leave healthy ears alone. If you have no symptoms, you do not need to clean deep inside the canal.
- Softening drops. Pharmacy olive oil, sodium bicarbonate, or proprietary wax softener drops are often tried for a few days, following the product label. NHS and local NHS trust pages describe drops as a first step to help wax move out naturally.
- One ear at a time if both feel blocked, so you keep one clearer ear while treating the other (as some GP self-care leaflets suggest).
- Stop if pain, discharge, or known eardrum perforation is present, and get clinical advice instead of continuing drops or irrigation at home.
Never insert cotton buds, ear candles, or sharp tools. They risk injury and often worsen impaction.
When professional removal makes sense
NICE CKS earwax management supports referral to an appropriate ear care or ENT service, depending on the person’s needs and local referral pathway, when wax needs removing and primary options are unsuitable or unsuccessful. Methods can include irrigation, microsuction, or manual removal under vision. NICE quality standard QS185 states that methods include ear irrigation, microsuction, or manual removal, and that irrigation may be contraindicated for some people.
Professional removal is reasonable when:
- Softening drops have not improved symptoms
- Hearing aids no longer fit or whistle because of wax
- You need a clear view of the eardrum for another reason
- Irrigation is unsuitable (for example after certain ear surgery, perforation history, or active infection), so a dry method under magnification is preferred
Microsuction in plain terms
Microsuction uses gentle medical suction while the clinician views the canal under magnification. It is a dry technique: no pressurised water is forced into the ear. That can suit people for whom water irrigation is a poor fit. Suitability still depends on individual assessment. No method suits every ear, and outcomes vary.
