Causes of fullness in one ear

Overview

Fullness in one ear is a feeling of pressure, blockage, or stuffiness in just one ear. It can feel like you are underwater or like something is inside your ear.

Yes, many people experience fullness in one ear at some point in their lives.

It can affect anyone, from children to older adults. It is especially common in people who swim a lot, have allergies, or get frequent colds.

Symptoms

Common symptoms

• Feeling of pressure or blockage in one ear
• Muffled hearing or hearing loss in that ear
• A popping or clicking sensation when swallowing or yawning
• Mild discomfort or a sense of fullness

Symptoms in children

• Tugging or pulling at the affected ear
• Irritability or crying more than usual
• Trouble sleeping or hearing
• Fever if an infection is present

Symptoms in older adults

• Feeling of pressure that may be mistaken for hearing loss
• Dizziness or balance problems if the inner ear is involved
• Difficulty hearing conversations clearly

Causes

Main causes

• Earwax blockage: too much earwax can harden and block the ear canal.
• Eustachian tube dysfunction: the tube that connects your ear to your throat may be blocked by allergies, colds, or sinus infections.
• Fluid behind the eardrum (otitis media with effusion): often after an ear infection, fluid stays in the middle ear.
• Swimmer’s ear (otitis externa): an infection of the outer ear canal from water or moisture.
• Changes in air pressure during flying or diving (airplane ear).

Risk factors

• Being around cigarette smoke
• Allergies or frequent colds
• Swimming or bathing in dirty water
• Using cotton swabs (Q-tips) inside the ear
• Having a narrowed or damaged ear canal

When to see a doctor

See a doctor urgently if:

• If you have sudden hearing loss or severe pain
• If you have a fever or discharge from the ear

Book a routine appointment if:

• If the fullness lasts more than a week
• If it is affecting your daily life or hearing

Diagnosis

Your doctor will ask about your symptoms and look inside your ear with a lighted tool called an otoscope. They may also gently blow air into your ear to check how your eardrum moves.

Tests that may be done

• Otoscopy: looking into the ear with a special tool
• Tympanometry: a test that checks the movement of the eardrum
• Hearing test (audiometry) if hearing loss is suspected

What to expect at your appointment

The appointment usually takes 10-15 minutes. Your doctor may also check your nose and throat to look for swelling or congestion.

Treatment

Treatment depends on the cause. Many cases improve on their own or with simple home care. If an infection is found, your doctor may recommend drops or other treatments. Surgery is rarely needed.

Self-care at home

• Gently chew gum, yawn, or swallow to open the Eustachian tube
• Apply a warm, moist cloth over the ear for comfort
• Avoid putting anything inside your ear, including cotton swabs
• For earwax blockage, try over-the-counter ear drops (ask your pharmacist) or a few drops of warm olive oil

Medical treatments

If the cause is an infection, your doctor may prescribe ear drops or antibiotics. If allergies are involved, antihistamines or nasal sprays might be recommended. For persistent fluid, a procedure to place small tubes in the eardrum may be suggested. Always follow your doctor’s advice.

When is surgery considered?

Surgery is only considered for chronic problems that do not get better, such as repeat ear infections or a persistent hole in the eardrum. Your doctor will discuss this with you if needed.

Living with this condition

Most people with ear fullness can continue their normal activities. If hearing is affected, you may need to ask people to speak more clearly or use subtitles on TV.

Lifestyle tips

• Avoid smoking and secondhand smoke
• Protect your ears from water by using a shower cap or earplugs when swimming
• Dry your ears gently after bathing

Diet and exercise

There are no specific dietary restrictions. Staying hydrated may help thin mucus if congestion is the cause. Exercise is fine, except for contact sports if you have a recent ear injury or surgery.

Mental health and emotional wellbeing

Long-lasting ear fullness or hearing loss can feel frustrating or stressful. It may make conversations tiring. Let your doctor know if it affects your mood or sleep. They can help find ways to cope.

Prevention

You can reduce the risk of ear fullness by treating allergies and colds early, avoiding inserting objects into your ears, and protecting your ears from water and changes in air pressure. Yawning or swallowing during takeoff and landing on flights can help prevent airplane ear.

Vaccines

Some ear infections can be prevented by vaccines, such as the flu vaccine and the pneumococcal vaccine. Ask your doctor about these if you are at risk.

Screening programmes

There are no routine screening tests for ear fullness. However, if you are a swimmer or have frequent ear infections, your doctor may suggest occasional check-ups.

Complications

If left untreated

• Hearing loss that may become permanent if the cause is not treated
• Spread of infection to the skull or brain (rare but serious)
• Chronic ear disease or repeated infections

Long-term outlook

The outlook for fullness in one ear is very good. Most causes are treatable and do not lead to long-term problems. With proper attention, nearly everyone recovers fully.
