Otitis externa (External ear infection)

Otitis externa is inflammation of the ear canal that commonly causes ear pain, itching or a feeling of fullness. Below are general facts about typical symptoms, frequent causes, prevention measures and which specialists handle this condition.

Symptoms and clinical presentation

Typical complaints include local ear pain that worsens with touching the outer ear, itching, sensitivity of the ear canal and sometimes discharge. Affected ears may feel blocked or have temporary hearing reduction. Severity ranges from mild discomfort to intense pain; accompanying fever is less common but should prompt evaluation.

Common causes and risk factors

Episodes often follow water exposure (for example swimming), injury from inserting objects into the ear, or skin conditions such as eczema that break the ear’s protective barrier. Warm, moist environments and recent antibiotic use or immune suppression can change the ear canal flora and increase risk.

Prevention and everyday care

Keep the ear canal as dry and intact as possible: dry ears gently after water exposure, avoid inserting cotton swabs or other objects, and protect ears during swimming if you are prone to irritation. Treating underlying skin conditions and maintaining good ear hygiene reduce recurrence risk.

When to seek medical assessment and what to expect

Primary contact points are family physicians and ear-nose-and-throat (ENT) specialists. An examination with an otoscope inspects the ear canal and eardrum; the clinician will assess severity and may recommend follow-up or referral. Seek prompt care if pain is severe, symptoms worsen, or hearing changes markedly.
