Understanding Swimmer's Ear: Causes and Risk Factors

Swimmer's ear, medically known as otitis externa, is an infection of the ear canal—the tube that runs from your outer ear to your eardrum. This condition occurs when water becomes trapped in the ear canal, creating a warm, moist environment where bacteria and fungi can grow. Unlike a middle ear infection (which happens behind the eardrum), swimmer's ear affects the outer ear canal itself.

The infection typically develops when bacteria, most commonly Pseudomonas aeruginosa or Staphylococcus aureus, colonize the ear canal. Water alone does not cause the infection; rather, prolonged moisture breaks down the protective earwax and skin barrier that normally prevents bacterial growth. When this protective layer weakens, bacteria can penetrate and cause inflammation.

Several factors increase your risk of developing swimmer's ear. Frequent swimming or water activities expose your ears to moisture regularly. Showering, especially if water enters your ears, can also contribute. Humidity and sweating create moist conditions. Using cotton swabs or other objects to clean your ears damages the protective skin lining. Hearing aids and earbuds that block airflow can trap moisture. Certain skin conditions like eczema or psoriasis make ears more vulnerable. People with narrow ear canals may be at higher risk because water is more likely to remain trapped.

Climate plays a role too. Swimmer's ear is more common in summer months and in warm, humid climates. Chlorine and other pool chemicals can irritate the ear canal, making it more susceptible to infection. Saltwater exposure may have similar effects. Even small cuts or abrasions in the ear canal—from scratching, aggressive cleaning, or aggressive cotton swab use—create entry points for bacteria.

Practical takeaway: Recognize that swimmer's ear develops when moisture combines with a compromised ear canal barrier. Understanding these causes helps explain why prevention methods focus on keeping ears dry and avoiding injury to the ear canal.

Recognizing Symptoms and When to Seek Medical Attention

Swimmer's ear symptoms usually appear within one to three days of water exposure, though they can develop more slowly. Early symptoms are often mild and may include itching deep inside the ear canal, a slight discomfort, or a feeling of fullness in the ear. These initial signs may seem minor, but they indicate that infection is beginning.

As the infection progresses, symptoms typically worsen. Pain becomes more pronounced and may intensify when you touch your ear or chew. Some people experience pain that radiates to the jaw, neck, or side of the face. Drainage from the ear—which may be clear, yellowish, or contain pus—is common. Hearing may become muffled or reduced in the affected ear. Itching intensifies and may become severe. Swelling of the ear canal can cause a feeling of pressure or fullness. In some cases, redness and swelling visible around the ear opening occur.

Severe infections can cause more serious symptoms. Fever may develop. Swollen lymph nodes near the ear may become tender. In rare cases, the infection can spread, causing cellulitis (spreading skin infection) or, in very severe untreated cases, affecting the temporal bone. However, such complications are uncommon with timely treatment.

You should seek medical attention if you experience ear pain and suspect swimmer's ear, particularly if you've had recent water exposure. A healthcare provider can examine your ear canal with an otoscope (a lighted instrument) to confirm the diagnosis. Medical evaluation is important because other conditions can mimic swimmer's ear symptoms, including middle ear infections, earwax buildup, or temporomandibular joint (TMJ) problems. A provider can distinguish between these conditions and recommend appropriate treatment.

Do not attempt to treat swimmer's ear with over-the-counter medications intended for other ear conditions, such as those for middle ear infections, without professional guidance. Using the wrong treatment may worsen your condition or delay proper healing.

Practical takeaway: Early symptoms include itching and mild discomfort; pain and drainage indicate infection is progressing. Contact a healthcare provider when symptoms appear, especially if you've been in water, to receive a proper diagnosis and suitable treatment plan.

Home Care and Self-Treatment Options

If your healthcare provider diagnoses swimmer's ear or suspects it based on your symptoms, several at-home care strategies can complement medical treatment and support healing. These approaches focus on keeping the ear dry, reducing pain, and preventing the infection from worsening.

Keeping your ear dry is the most important step. After bathing or swimming, gently dry your outer ear with a soft cloth. You can tilt your head to help water drain from the ear canal. Some people find it helpful to use a hair dryer on the lowest setting held several inches from the ear to gently dry the canal. Never insert the dryer tip into the ear. If water enters your ear during treatment, use a clean tissue or cloth to absorb surface moisture without inserting anything deep into the canal.

Over-the-counter pain relievers containing ibuprofen or acetaminophen may reduce pain and discomfort while you're being treated for the infection. Follow package directions for dosing. A warm compress applied to the outside of the ear can provide comfort. Heat often soothes pain temporarily, though it does not treat the infection itself.

Some people apply over-the-counter eardrops designed to help dry the ear canal, though these should only be used if your eardrum is intact (your doctor will confirm this). Products containing isopropyl alcohol or acetic acid may help dry moisture. However, do not use these if you have discharge from your ear, as they may enter the middle ear and cause problems. Never use vinegar or other home remedies without medical guidance, as improper application can worsen infection or damage delicate ear structures.

Avoid inserting anything into your ear canal, including cotton swabs, bobby pins, or fingers. These objects can introduce bacteria, damage the already-inflamed skin, or push infection deeper into the canal. If earwax buildup is contributing to discomfort, your healthcare provider can safely remove it.

Use a cotton ball lightly coated with petroleum jelly to loosely plug your ear during bathing if your provider recommends it. This prevents water entry without trapping moisture inside. Remove it immediately after bathing.

Practical takeaway: Home care focuses on drying the ear, managing pain, and avoiding further injury. These steps support medical treatment but do not replace it—antibiotic treatment is usually needed to eliminate the infection.

Medical Treatment Options and Antibiotic Drops

Most cases of swimmer's ear require medical treatment, typically involving antibiotic eardrops prescribed by a healthcare provider. These medications directly target the bacterial infection in the ear canal and are the standard treatment approach.

Antibiotic eardrops come in several formulations. Common options include drops containing neomycin, polymyxin B, and hydrocortisone (such as those sold as Neosporin Otic or similar brands). Other formulations use ciprofloxacin, ofloxacin, or gentamicin. Some drops include steroids to reduce inflammation alongside the antibiotic. Your provider selects the most appropriate option based on the infection severity and your medical history.

To use antibiotic eardrops correctly, follow your provider's instructions precisely. Generally, you'll lie on your side with the infected ear facing upward. Using the dropper provided, place the recommended number of drops (often 4-5) into the ear canal. Remain in this position for several minutes to allow the drops to coat the infected area. Some providers recommend gently moving your jaw or pulling the ear to help the drops penetrate. You may be instructed to place a cotton ball in your ear afterward to prevent the drops from leaking out. Wash your hands after application. Most treatment regimens involve using drops three to four times daily for 7-10 days.

If earwax or discharge is blocking the ear canal, your healthcare provider may need to clean it out before drops can be effective. This cleaning may be done during an office visit using special instruments or suction. Some providers use a small curette (a thin, curved instrument) to gently remove debris. This procedure is not painful, though it may cause slight discomfort.

In more severe cases or if the ear is significantly swollen, your provider might insert an ear wick—a small sponge
