If you’ve ever had that sharp, itching pain inside your ear after swimming or showering, you probably experienced otitis externa, commonly called swimmer’s ear. This infection affects the outer ear canal and can turn a simple itch into throbbing discomfort in just a day or two. The good news? Most cases clear up with easy at‑home steps and a short course of medication.
The first clue is usually an itching sensation that quickly becomes pain, especially when you touch your ear or pull on the earlobe. You might notice redness, swelling, or even a little discharge that looks watery or pus‑filled. Some people hear a muffled sound because fluid builds up in the canal. If these symptoms show up within 24‑48 hours after water exposure, it’s likely otitis externa.
Start by keeping your ear dry. Gently towel‑dry the outer ear and tilt your head to let any trapped water drain out. Over‑the‑counter pain relievers like ibuprofen can calm the ache, while a few drops of warm olive oil (cooled to body temperature) may soothe itching—just don’t use this if you suspect a ruptured eardrum.
If the pain is stubborn, an over‑the‑counter ear drop containing acetic acid or alcohol helps dry out excess moisture and fights bacteria. Apply the drops as directed, usually three times a day for a week. Avoid inserting cotton swabs; they can push debris deeper and worsen the infection.
Most cases improve in a few days, but see a doctor if you notice severe pain, swelling that spreads beyond the ear, fever above 100.4°F (38°C), or discharge that’s thick and foul‑smelling. A healthcare provider may prescribe prescription antibiotic drops or oral medication if the infection is more intense.
In rare cases, a fungal infection can develop, especially after prolonged moisture exposure. If you’ve been treating with standard drops for over a week without relief, ask your doctor about antifungal options.
The best defense is keeping the ear canal dry. Use ear plugs or a swim cap when swimming, and after water activities, tilt your head and gently pull on the earlobe to let water escape. For frequent swimmers, a few drops of diluted vinegar solution (one part white vinegar to one part water) after drying can keep the canal’s pH hostile to bacteria.
Regularly cleaning the outer ear with a washcloth—never inserting anything into the canal—keeps wax and debris from trapping moisture. If you have eczema or psoriasis in the ear, discuss preventive creams with your doctor to reduce irritation that can lead to infection.
Remember, otitis externa is usually short‑lived when caught early. A few practical steps at home, combined with prompt medical care for tougher cases, will get your ears back to normal without missing a beat.
