Ear discharge (Otorrhoea)

Ear discharge is when fluid (discharge) comes out of the ear. It can have a foul smell and can be thick or watery. While this can be caused by a build-up of excess earwax, it may also be a sign of a problem that needs treatment.

What is ear discharge?

We all have earwax. It’s a natural, protective substance produced by glands in your ear canal, made from sebum, sweat, dead skin cells, and trapped debris. Earwax is a light or dark brown substance that helps keep your ears clean and prevents dust and bacteria from getting in your ears.

But some people make excess earwax, and ear discharge (otorrhoea) can be your body’s way of getting rid of it. Other times, ear discharge can be a sign of an ear problem or injury.

Our ear, nose and throat (ENT) specialists see patients with ear discharge in our purpose-built ENT Health centre, where they offer the most advanced care in both diagnostics and treatment.

More information

Ear discharge can trigger a range of symptoms, depending on what’s causing it. The fluid might contain wax, blood, and pus. You might also notice pain, itching, or ringing in your ear. 

More serious symptoms can include:

  • loss of hearing

  • dizziness

  • fever

  • redness (erythema) of the skin around your ear

  • cranial nerve dysfunction – it can cause difficulty swallowing, speaking, or seeing

  • vertigo – feeling like the room is spinning

There are many reasons why you might have ear discharge, but the most common is an ear infection, which can include:

  • a middle ear infection (otitis media) – when a build-up of fluid behind the eardrum can sometimes cause the eardrum to burst. This triggers severe pain and a thick yellow fluid to run out of the ear. It’s common in children, but it can happen at any age

  • an outer ear infection (otitis externa or swimmer's ear) – when the skin inside your ear canal swells and gets infected. It causes discharge to build up in the ear canal and drain out of the ear

  • mastoiditis – an infection of the bone behind your ear

  • malignant otitis externa – an infection of your ear canal and part of the skull

Aside from ear infections, ear discharge can be caused by:

  • damage to your eardrum – your eardrum can tear if you push an object, such as a cotton bud, in too deeply. It can also be damaged due to changes in pressure, such as on a plane, which can cause fluid to leak through the hole and out of your ear

  • an object in the ear – it usually happens if a child puts something like a small toy or a stone in their ear, causing fluid containing blood or pus to leak from their ear

  • eczema of the ear – it can cause clear liquid to leak from your ear

  • cholesteatoma – an abnormal growth of cells in the middle ear, which can cause fluid with a bad smell to leak from your ear

  • a serious head injury – when fluid from your brain, that’s clear or blood-stained, leaks out of your ear. This is a medical emergency

Ear discharge risk factors

You might be more likely to get ear discharge if you:

  • have had a recent head or ear injury

  • have diabetes, eczema or dermatitis

  • are a regular swimmer

  • are prone to ear infections

  • have recently had a cold or the flu

  • have a cleft palate

  • have Down’s syndrome

  • have a weakened immune system

If you have ear discharge or any other related symptoms, we recommend making an appointment with one of our consultants in our outpatient ENT centre. At a consultation, your specialist will ask about your symptoms, your medical history, and check inside your ear for signs of earwax build-up, a ruptured eardrum, and an ear infection.

In some cases, your consultant may perform a CT or MRI scan to check the middle and inner sections of your ear in more detail. They may also take a culture sample from your ear discharge to see if any bacteria or fungi grow from it. 

In other cases, you may need audiometry tests to check your hearing. Effective treatment will be based on the results of your tests.

Most causes of ear discharge are unavoidable, which means you can’t completely prevent the condition. But you might be able to reduce the risk of it by:

  • wearing specialised earplugs when you’re swimming, if you keep getting swimmer’s ear

  • not putting anything in your ears – this includes cotton buds, or any other objects, to clean inside your ears

  • not flying and/or diving, if you have a blocked nose

  • drying your ears after swimming or showering

  • wearing a helmet when riding a bike or playing contact sports, to prevent injuries

Complications of ear discharge depend on the cause. Ear infections are the most common trigger for ear discharge, and if left untreated, they can spread to other areas of the body, causing complications such as:

  • facial paralysis

  • perforated eardrum

  • partial or complete hearing loss

  • inner ear infection (labyrinthitis)

  • infection of tissues covering your brain (meningitis)

But this is rare and can be prevented with proper treatment.

Treatments for ear discharge vary depending on what’s causing the problem. They can include:

  • medicines – antibiotics may be used in tablet or eardrop form, if an ear infection doesn’t go away, or you’ve had an injury to your eardrum

  • removal of an object – if something is stuck in your ear, it can be removed with microsuction. A microscope may also be used to check the health of your ear at the same time

  • surgery – to remove a cholesteatoma, or to close the hole created by a perforated eardrum

Frequently asked questions

Chronic otorrhea is when ear discharge lasts for longer than 6 weeks. It’s more common in children but can affect adults too, and is often caused by a problem with the eardrum.



Runny earwax is often normal. Many things can affect the texture of your earwax, such as age, genetics, and your environment. But if you notice changes to your earwax, you have fluid leaking from your ear, or you have other symptoms, such as ear pain or hearing loss, see a doctor or specialist as soon as possible.

It's usually safe to fly if you have a perforated eardrum. But if you've had surgery to repair it (myringoplasty), you mustn’t fly until you're told it’s safe to do so.

Antibiotics should start to get rid of an ear infection and improve your symptoms within 2 to 3 days. Some symptoms may take up to a week to fully settle – you might still notice fluid leakage from your ear and have some hearing issues for a few weeks. It’s important to take the full course of antibiotics you’ve been prescribed, which can help stop the infection from coming back.
