A feeling of fullness, muffled hearing, or a bubbling sound inside your ear can sometimes mean there’s fluid trapped behind the eardrum. This can happen for a variety of reasons - from water getting stuck after swimming, to inflammation or fluid build-up behind the eardrum. In most cases, it’s temporary and harmless, but if it lingers or causes discomfort, it may need professional attention.

At Leightons, our audiologists can help determine what’s causing the problem and provide safe, effective solutions for clearer, more comfortable hearing.

What is fluid in the ear?

“Fluid in the ear” can refer to two main types of issues:

  • Outer ear fluid (in the ear canal): Often caused by trapped water, ear wax, or an outer ear infection (otitis externa). This is the type people might experience after swimming or showering.
  • Middle ear fluid (behind the eardrum): Also known as middle ear effusion or glue ear, this happens when fluid collects in the space behind the eardrum, often due to infection or Eustachian tube dysfunction.

While both types can cause similar sensations of blockage or muffled hearing, the causes and treatments are different. A professional ear examination can identify which type you have and what needs to be done.

Common causes of fluid in the ear

Fluid in or behind the ear can result from several different factors:

  • Water trapped in the ear canal: After swimming, bathing, or using earbuds.
  • Ear infections (otitis externa or otitis media): Infection can create fluid, discharge, or swelling.
  • Eustachian tube dysfunction: When the tubes connecting the middle ear and throat are blocked, fluid can’t drain properly.
  • Colds, allergies or sinus congestion: Can lead to inflammation and pressure changes.
  • Glue ear: A chronic condition where thick fluid builds up behind the eardrum, common after repeated infections.
  • Pressure changes: Flying or diving can temporarily affect ear pressure and cause fluid movement.

Symptoms to watch for

Fluid in the ear can feel different depending on where it sits and how much there is. Common symptoms include:

  • A feeling of fullness or blockage in one or both ears
  • Muffled or reduced hearing
  • Popping, crackling or bubbling sounds
  • Itching, irritation or mild pain
  • Drainage or discharge (in the case of infection)
  • Balance problems or dizziness

If these symptoms persist for more than a few days, or are accompanied by pain or discharge, it’s best to see an audiologist or GP.

Is fluid in the ear serious?

In most cases, fluid in the ear will clear naturally once the underlying cause (like trapped water or congestion) resolves. However, persistent fluid, especially behind the eardrum, can lead to temporary hearing loss or recurring infections if left untreated.

For children, long-term fluid in the middle ear can sometimes affect hearing and speech development - so early assessment is important.

How to treat fluid in the ear

Treatment depends on whether the fluid is in the outer or middle ear.

For outer ear fluid:

  • Tilt your head or gently pull on your earlobe to help water drain.
  • Avoid inserting cotton buds or objects into the ear.
  • If symptoms persist, professional cleaning or drops may be needed to treat infection or inflammation.

For middle ear fluid:

  • Observation: Mild cases often resolve naturally.
  • Decongestants or nasal sprays: To be used with guidance from a GP or pharmacist, it helps open the Eustachian tubes for drainage.
  • Antibiotics: Used if the fluid is linked to an infection.
  • ENT referral: In chronic cases (like glue ear), a specialist may recommend minor drainage procedures.

Leightons’ audiologists can carry out safe ear examinations and hearing assessments to identify the cause and guide you to the most appropriate treatment.

  • Yawn or swallow during flights and altitude changes
  • Schedule regular ear health checks if you’re prone to congestion, infections, or wax build-up

Vertigo: causes, symptoms and how to find relief
Feeling dizzy or as though the room is spinning can be unsettling. This sensation, known as vertigo, often comes from a problem in the inner ear, which helps control balance. While vertigo can feel alarming, it’s usually treatable and often linked to conditions that are temporary or easily managed. At Leightons, our audiologists are here to help you understand what’s behind your dizziness and guide you toward the right care, offering safe and professional support for your ear and balance health. What Is vertigo? Vertigo isn’t a condition itself, but a symptom - a feeling that you or your surroundings are moving when they’re not. It’s usually caused by an issue in the vestibular system, the part of your inner ear responsible for balance. Some people describe vertigo as feeling like spinning, swaying, or tilting. It can last a few seconds or persist for longer periods, depending on the cause. What causes vertigo? Vertigo can occur for several reasons, many of which are related to the inner ear. Common causes include: Benign paroxysmal positional vertigo (BPPV): The most common cause of vertigo, where small crystals in the inner ear move out of place and trigger dizziness during head movements. Inner ear infections: Conditions such as labyrinthitis or vestibular neuritis cause inflammation that affects balance and hearing. Meniere’s disease: A long-term condition involving fluid build-up in the inner ear, leading to vertigo, tinnitus, and hearing changes. Ear wax blockage: In some cases, a build-up of wax can affect pressure or balance, leading to dizziness. Migraine-associated vertigo: Some migraines cause dizziness, even without a headache. Circulatory or blood pressure changes: Less commonly, vertigo may stem from reduced blood flow to the inner ear or brain. Common symptoms of vertigo Vertigo can vary in intensity and duration. You may experience: A spinning or swaying sensation Loss of balance or unsteadiness Nausea or feeling light-headed Ringing or pressure in the ears (tinnitus) Hearing loss or muffled sounds Headache or visual disturbance If vertigo is sudden, persistent, or severe, it’s important to have it checked by a professional. When to seek professional advice Occasional dizziness after standing up too quickly or turning your head isn’t unusual. However, you should seek advice if: Vertigo happens frequently or lasts longer than a few minutes You experience hearing changes or ringing in your ears You have nausea, vomiting, or difficulty walking Vertigo occurs alongside ear pain or infection symptoms While vertigo itself isn’t usually dangerous, the underlying cause may require treatment. A hearing and balance assessment can help identify the issue and offer reassurance. Diagnosis and treatment Your treatment will depend on what’s causing your vertigo. Common approaches include: Canalith repositioning manoeuvres: Simple head movements (such as the Epley manoeuvre) to correct BPPV. Medication: To ease inflammation, nausea, or dizziness caused by infection. Vestibular rehabilitation: Special exercises that retrain your balance system. Ear wax removal: If a blockage is affecting balance. ENT referral: For more complex or persistent cases.
