When dealing with otitis externa, an infection of the outer ear canal that often causes itching, pain, and discharge. Also known as swimmer's ear, it typically arises after water exposure or trauma to the ear. The condition involves bacterial infection, most commonly caused by Pseudomonas or Staphylococcus species or fungal infection, especially in humid climates. Effective treatment relies on ear drops, medicated solutions that deliver antibiotics or steroids directly to the canal and proper ear hygiene, keeping the ear dry and clean to prevent recurrence. These elements together form the core of otitis externa care.
Six main factors raise the risk: prolonged water exposure, use of cotton swabs, hearing aids, skin conditions like eczema, allergic reactions, and a weakened immune system. When the ear canal stays moist, bacteria or fungi find a perfect breeding ground. Even a tiny scratch from a Q-tip can open the door for microbes. Recognizing these triggers helps you cut down on future episodes.
Typical symptoms appear within a day or two: sharp pain when pulling the ear, redness and swelling of the canal, muffled hearing, and a clear or yellowish discharge. A simple otoscopic exam lets a clinician see the inflamed skin and confirm the diagnosis. No blood tests are needed; visual inspection is enough.
Treatment starts with cleaning the ear—often a healthcare professional will flush the canal to remove debris. Then, doctors prescribe antibiotic ear drops for bacterial cases or antifungal drops for fungal origins. Over‑the‑counter pain relievers like ibuprofen or acetaminophen can ease discomfort. In severe cases, oral antibiotics or steroids may be added.
