Blocked ears can make ordinary conversations feel like hard work. You may find yourself asking people to repeat themselves, turning up the television or noticing your own voice sounds unusually loud. The causes of blocked ears range from a simple build-up of wax to a cold, pressure changes or an ear infection. The right next step depends on what is causing the sensation – and on any other symptoms you have.
Earwax is one of the most common reasons for a blocked feeling, muffled hearing or pressure in the ear. Despite its bad reputation, wax has a useful job: it helps trap dust and debris, protects the delicate skin of the ear canal and usually works its way out naturally.
Problems start when wax builds up or becomes impacted. This can happen because some people simply produce more wax, while others have narrow or bendy ear canals where it does not clear as easily. Hearing aids, earplugs and in-ear headphones can interfere with the ear’s natural movement of wax and may contribute to wax build-up when worn regularly. Frequent swimmers may notice a change too, as water may become trapped around existing wax, making the blockage or reduced hearing more noticeable.
Cotton buds are a frequent culprit. They may seem to remove wax, but they often push it further in, compacting it near the eardrum. If your symptoms began after using a bud or putting anything else in your ear, stop trying to clear it yourself. More probing can irritate the canal, damage the skin or make a wax blockage harder to remove.
Your middle ear is connected to the back of your nose by a small passage called the Eustachian tube. Its job is to balance pressure on either side of the eardrum. When you have a cold, hay fever, sinus congestion or another upper respiratory infection, this tube can become swollen or blocked.
The result is often pressure, popping, crackling or a feeling that your ear needs to clear. Hearing can seem dull even though there is no wax in the ear canal. This type of blockage often settles as the cold or allergy improves, though it can linger for a few weeks. Gentle swallowing, yawning and staying well hydrated may help, but avoid forcefully blowing your nose or trying aggressive pressure-clearing techniques if they cause pain.
A blocked sensation during a flight is usually caused by rapid changes in air pressure. The same thing can happen in fast lifts, on mountain roads or while diving. Your Eustachian tube needs to open to equalise pressure, and it may struggle if you are congested or have a cold.
Chewing, swallowing or sucking a sweet during take-off and landing can help many adults. If you are unwell with a heavy cold, flying may be more uncomfortable than usual. Divers should not dive with congestion or ear pain, as pressure problems underwater can cause injury.
After swimming, showering or washing your hair, water can sit behind a small amount of wax or become trapped in the folds of the ear canal. It often feels like the ear is full, and you may hear a faint sloshing sound or notice your hearing changes when you tilt your head.
Usually, this clears on its own. Tipping your head towards the affected side and gently pulling the outer ear can encourage drainage. Do not insert tissue, buds, hairpins or other objects into the canal. Persistent dampness, itchiness, pain or discharge can point to irritation or swimmer’s ear and should be assessed.
An outer-ear infection can cause swelling in the ear canal, creating a blocked feeling alongside itchiness, tenderness and sometimes discharge. It is often more painful when you pull the outer ear or press the small flap of skin at the front of it. Water exposure, skin conditions and scratching inside the ear can all increase the chance of irritation.
Middle-ear infections are more likely to cause deeper pain, pressure, reduced hearing and occasionally fever. They can follow a cold and are particularly common in children, although adults get them too. Wax removal will not fix an infection, so it is worth getting the cause checked rather than assuming every blocked ear is a wax problem.
Anything worn regularly in the ear can change how wax moves out. Hearing-aid users are especially prone to wax build-up because the device can reduce natural ventilation and clearance. Earplugs and earbuds can have a similar effect when used for long periods.
Eczema, psoriasis and dry skin can also affect the ear canal. Flaking skin may collect with wax, while scratching can create soreness and swelling. If blocked ears keep returning, the answer may be a simple maintenance plan rather than waiting until hearing becomes noticeably reduced.
Wax-related blockage often develops gradually. You may notice muffled hearing in one or both ears, a full sensation, mild discomfort, ringing, or hearing that changes after a shower or swim. Some people can hear their own chewing or voice more loudly.
These symptoms can suggest wax, but they cannot confirm it. A clinician needs to look into the ear to see whether wax is present, how much there is and whether it is safe to remove. This matters because the same symptoms can also come from fluid behind the eardrum, infection or another ear condition.
If wax is confirmed, microsuction is a controlled method that removes it under direct visual guidance. Microsuction does not involve flushing water into the ear and may sometimes be considered when irrigation is unsuitable. However, previous ear surgery, perforated eardrum or recurrent infections require careful assessment before treatment. Always disclose your full ear history when booking.
If you have no pain, discharge, suspected perforation or previous advice to avoid drops, pharmacy earwax-softening drops may help soften wax before an appointment. Follow the product instructions carefully and give them time to work. Softening drops can occasionally make the ear feel temporarily more blocked before wax is removed, particularly when there is a larger plug.
Keep the rest of your approach simple. Avoid cotton buds, ear candles and improvised tools. Ear candles do not remove wax and carry a real risk of burns or wax residue in the canal. Avoid home irrigation kits unless a qualified professional has advised they are appropriate for you, especially if you have diabetes, a history of ear problems or uncertainty about your eardrum.
For congestion-related pressure, rest, fluids and managing your cold or allergy symptoms may be enough. Speak to a pharmacist if you are unsure which treatments are suitable alongside your usual medicines or health conditions.
Most blocked ears are not an emergency, but some symptoms should not be left to see if they pass. Seek urgent medical advice and assessment if hearing becomes suddenly reduced over 3 days or less, particularly if this has happened within the last month. Contact NHS 111, request an urgent GP assessment or attend an emergency department. Sudden hearing loss needs prompt assessment and should not be treated as routine wax.
You should also seek urgent help for severe ear pain, bleeding, pus-like discharge, swelling around the ear, fever with significant illness, severe dizziness, facial weakness, or symptoms after a head injury. Children, people with a weakened immune system and anyone with previous ear surgery should be particularly cautious.
A blocked ear is frustrating, but guessing is rarely the best route. If the feeling has persisted, keeps returning or is affecting work, sleep or everyday conversations, an ear examination can quickly show whether wax is involved. At Drub, trained ear-care practitioners use direct-visualisation microsuction and explain what they can see before treatment, so you are not left wondering what is happening.
Your ears do not need harsh cleaning to stay healthy. A little patience, the right assessment and prompt care when symptoms change can make hearing clearly feel simple again.
