Swimmer’s ear is an infection of the outer ear canal, and the first thing to do is dry the ear, manage the pain, and get antibiotic ear drops if symptoms don’t resolve quickly. Most uncomplicated cases clear up within five days with proper treatment, and symptoms often start improving within one to three days.
Dry the Ear and Stop the Moisture
Water trapped in the ear canal creates the warm, moist environment bacteria need to multiply. Your immediate priority is getting it out and keeping it out. Tilt your head to the side so the affected ear faces down, letting gravity pull the water free. Gently wipe the outer ear with a soft towel, but don’t push anything into the canal.
A blow dryer on its lowest heat setting, held at least a foot from your ear, can help evaporate lingering moisture. This sounds odd, but it works. The goal is airflow, not heat. While you’re dealing with swimmer’s ear, avoid swimming, stop using earbuds or hearing aids if possible, and try to keep the ear canal dry during showers. A cotton ball lightly coated in petroleum jelly placed at the opening of the ear can help block water while bathing.
Try a Vinegar and Alcohol Solution
If you’re confident your eardrum isn’t perforated (no recent trauma, no ear tubes, no sharp sudden pain followed by drainage), a 50/50 mixture of white vinegar and rubbing alcohol can help. The alcohol promotes drying while the vinegar creates an acidic environment that discourages bacterial and fungal growth. Pour about one teaspoon of the solution into the affected ear, let it sit for a moment, then tilt your head to drain it out.
This mixture works best as a preventive measure or at the very first signs of irritation. If you already have significant pain or swelling, skip the homemade drops. Alcohol on inflamed skin will sting intensely and may worsen irritation. Similar over-the-counter drying drops are available at most drugstores and can be gentler on sensitive tissue.
Managing the Pain
Swimmer’s ear can be surprisingly painful because the skin lining the ear canal is thin and tightly bound to the cartilage underneath, leaving little room for swelling. Over-the-counter pain relievers like ibuprofen, acetaminophen, or naproxen all help. Ibuprofen and naproxen also reduce inflammation, which can be useful since swelling in the canal is part of what drives the discomfort. Aspirin should not be given to anyone under 20 due to its link to Reye syndrome.
A warm washcloth or a heating pad on low, held against the outer ear, can also ease the ache. If you use a heating pad, stay awake while it’s on, and don’t use one on a child. Some earwax may drain as the warmth softens it, which is normal.
When You Need Prescription Ear Drops
Most swimmer’s ear infections require antibiotic ear drops to fully resolve. These prescription drops typically combine an antibiotic to kill the bacteria with a steroid to reduce redness, itching, and swelling. You’ll usually apply the drops two to four times a day for about a week. Symptoms commonly improve within 24 hours of starting treatment and resolve completely in seven to ten days.
If the ear canal is badly swollen, your doctor may place a small sponge wick into the canal so the drops can reach the infected tissue. This sounds uncomfortable, but it makes a significant difference in how quickly the medication works. The wick usually falls out on its own as swelling decreases.
One important safety note: certain antibiotic ingredients, particularly older types called aminoglycosides, can damage hearing if used in an ear with a perforated eardrum. These chemicals can pass through the perforation and reach the delicate structures of the inner ear, potentially causing permanent hearing or balance problems within just a few days. This is why your doctor will look at your eardrum before prescribing drops and why you should mention any history of ear tubes, ear surgery, or eardrum rupture.
Signs the Infection Is Getting Worse
Mild swimmer’s ear causes itching, slight redness, and some discomfort when you tug on your earlobe. That alone warrants a medical visit, but it’s not an emergency. What should send you to urgent care or the emergency room is severe pain, especially if it radiates to your face, neck, or the side of your head, or if you develop a fever.
Other signs that the infection is advancing include a completely blocked ear canal, visible redness or swelling of the outer ear itself, and swollen lymph nodes in the neck. In rare cases, particularly in people with diabetes or weakened immune systems, an outer ear infection can spread to the bone surrounding the ear canal. This is a serious complication that requires aggressive treatment, so don’t wait out worsening symptoms.
Preventing It From Coming Back
Swimmer’s ear tends to recur in people who swim regularly, live in humid climates, or have narrow ear canals that trap water easily. The most effective prevention strategy is keeping your ears dry after any water exposure. Tilt and drain each ear after swimming, towel-dry gently, and consider using the vinegar-alcohol drops as a preventive rinse after every swim.
Earplugs designed for swimming create a seal that keeps water out of the canal entirely. Custom-molded versions offer the best fit, but standard silicone plugs from a drugstore work well for most people. Swim caps can add another layer of protection if they cover the ears fully and fit snugly, though a loose cap won’t do much.
Avoid sticking anything into your ear canals, including cotton swabs. Swabs strip away the thin layer of earwax that naturally protects the canal’s skin and creates a slightly acidic, water-repellent barrier. Scratching the canal lining, even with a fingernail, creates tiny breaks in the skin where bacteria can take hold. If your ears feel waterlogged after swimming, resist the urge to dig around. Tilt, drain, and let airflow do the work.
