Swimmer's ear is infection or inflammation of the outer ear canal, often after water exposure. It differs from a middle-ear infection.
Symptoms
Ear pain, itching, discharge and tenderness when the outer ear is moved are common. The canal may feel blocked and hearing can be temporarily reduced.
The symptoms of swimmer's ear can overlap with other childhood conditions. Age, timing, severity and effects on breathing, hydration, feeding, sleep and activity help a clinician decide what assessment is needed.
Causes
Moisture, scratching, cotton buds, eczema and hearing devices can damage the canal skin and allow bacteria or fungi to grow.
Risk factors
A risk factor changes the likelihood of swimmer's ear but cannot confirm a diagnosis. Children without recognised risk factors may still be affected, while many children with risk factors never develop the condition.
Diagnosis
A clinician examines the ear canal and eardrum. A swab is reserved for severe, recurrent or treatment-resistant infection.
Online information cannot diagnose swimmer's ear. A qualified professional may need to examine the child, review medicines and medical history, and interpret tests in context.
Treatment
Prescribed ear drops are commonly used. Keep the ear dry during treatment and do not insert objects or unapproved drops.
Treatment for swimmer's ear should match the child’s age, weight, severity and other health needs. Check medicine names, doses and suitability with a qualified professional, and never use another person’s prescription.
Home care
When a professional has said that mild swimmer's ear can be managed at home, follow the care plan, support rest and fluids where appropriate, and note meaningful changes. Avoid unproven remedies and adult medicines.
Prevention
Not every case of swimmer's ear can be prevented. Current vaccination, hand and respiratory hygiene, safe food handling, trigger reduction and correct use of prescribed preventive treatment can lower relevant risks.
Possible complications
Possible complications of swimmer's ear depend on severity, duration and the child’s underlying health. Earlier review is appropriate when symptoms worsen, recovery stalls or normal drinking, breathing, sleep or activity is affected.
When to seek urgent medical care
Prompt care is needed for spreading redness, swelling behind the ear, severe pain, fever, diabetes, immune suppression or a child who seems very unwell.
If a child with possible swimmer's ear seems seriously unwell, seek urgent professional help even when every listed sign is not present. Call the local emergency number for collapse, unresponsiveness, severe breathing difficulty or another immediate threat to life.
Frequently asked questions
Can symptoms alone confirm the condition?
No. Symptoms associated with swimmer's ear may have several causes, so examination or tests may be needed before treatment is chosen.
Can home care replace an assessment?
Home care may support a mild, assessed case of swimmer's ear, but it cannot replace medical evaluation when warning signs, worsening symptoms or uncertainty are present.
When is follow-up appropriate?
Arrange follow-up for swimmer's ear when symptoms persist, recur, interfere with normal function or fail to improve as expected. Seek urgent help sooner if warning signs appear.
Summary
Swimmer's ear is infection or inflammation of the outer ear canal, often after water exposure. It differs from a middle-ear infection. Careful observation, evidence-based treatment and clear knowledge of urgent warning signs help families respond without trying to diagnose the child themselves.
