Swimmer’s ear is a common condition that can occur after swimming or other water activities. Though it can cause discomfort, it is usually easy to treat if addressed early. In this guide, we’ll explain what swimmer’s ear is, its causes, symptoms, and how to treat and prevent it.

What is Swimmer’s Ear

Swimmer’s ear, also known as otitis externa, is an infection of the outer ear canal caused by bacteria or fungi. The ear canal becomes inflamed and irritated, often due to prolonged water exposure. While this condition is most common among swimmers, it can affect anyone who spends time in water, particularly if the ear remains wet for extended periods.

Causes of Swimmer’s Ear

Swimmer’s ear is caused by various factors that contribute to moisture and bacteria entering the ear. Common causes include:

  • Water Exposure: Prolonged exposure to water, especially in warm or humid environments, creates a breeding ground for bacteria or fungi.
  • Inserting Foreign Objects: Using cotton swabs or other objects to clean the ear can push bacteria deeper into the ear canal, leading to irritation and infection.
  • Contaminated Water: Swimming in water that is not clean or contains bacteria increases the risk of developing swimmer’s ear.

Symptoms of Swimmer’s Ear

Recognising the symptoms of swimmer’s ear early can help you seek treatment quickly. Common symptoms include:

  • Itching in the Ear Canal: Often one of the first signs.
  • Redness or Swelling: The ear canal may appear red or swollen.
  • Pain or Discomfort: This is often aggravated when touching or pulling the earlobe.
  • Muffled Hearing: Fluid in the ear can cause temporary muffling or blockage of hearing.
  • Discharge: Pus or fluid leaking from the ear indicates infection.

Treatment of Swimmer’s Ear

If you suspect swimmer’s ear, several treatment options are available to relieve symptoms and clear the infection.

Ear drops

Over-the-counter ear drops are often effective for treating swimmer’s ear. These drops typically contain alcohol or acid to dry out excess moisture and restore the balance in the ear canal. Some ear drops may also include antibiotics or steroids to reduce inflammation and combat infection. Always follow the instructions on the packaging or consult a healthcare provider if unsure.

Pain medication

Over-the-counter pain relievers, such as paracetamol or ibuprofen, can help alleviate the discomfort and pain associated with swimmer’s ear. These medications help reduce inflammation and provide relief from ear pain.

Antibiotics

In more severe cases, a healthcare provider may prescribe oral or intravenous antibiotics to treat a bacterial infection. If the infection is fungal in nature, antifungal treatment may be recommended instead. It is important to complete the full course of antibiotics or antifungal medication, even if symptoms improve before you finish the treatment.

Surgery

In rare cases, if the infection is severe and does not respond to other treatments, surgery may be required to drain any fluid from the ear or remove any infection from the ear canal. This is typically reserved for cases where the infection has spread or caused significant damage.

When to Seek Professional Help

While most cases of swimmer’s ear can be managed at home, there are certain symptoms that warrant medical attention. If you experience significant pain, fever, or swelling around the ear, or notice pus or blood drainage, it’s important to consult a healthcare provider. If symptoms persist or worsen, professional treatment may be necessary.

Don’t insert foreign objects in to your ears

It isn’t advisable to insert any cotton swabs, hairpins, or other objects into your ear canal. These can push wax further into the ear, potentially causing blockages and infections. Always consult a healthcare professional for best advice and to avoid unnecessary damage to your ears which can often lead to irreversible hearing loss.

Check water isn’t contaminated

Whenever you expose your ears to water, make sure it’s clean and free from harmful bacteria. Swimming in chlorinated pools is safer than in lakes or ponds, which may harbour bacteria or other contaminants.
