### What Causes Swimmer's Ear and How to Treat It Swimmer's ear, or otitis externa, is an infection of the ear canal. This condition is often associated with swimming, but you can also get it on dry land. The main cause is bacteria, though viruses or fungi can also be responsible. Here are some common causes: - **Moisture trapped in the ear**: Water from swimming, bathing, or even humid weather can get stuck in the ear canal, removing earwax and softening the skin, making it easier for germs to enter. - **Scratches or abrasions**: Using cotton swabs or inserting other objects into the ear can scratch the skin, allowing germs to infect the ear canal. ### Symptoms Common symptoms include: - Ear pain, especially when tugging or pressing the ear - Itching inside the ear - Redness or swelling of the ear - Drainage of fluid from the ear ### Treatment If you suspect you have swimmer's ear, see a doctor promptly. Treatment usually involves: - **Cleaning the ear**: Your doctor may gently clean your ear to help treatments work better. - **Eardrops**: These may contain antibiotics, steroids, or other ingredients to fight the infection and reduce swelling. - **Oral antibiotics**: In severe cases, you may need to take antibiotic pills. Most people start to feel better within 2 days of starting treatment. However, if symptoms worsen or you experience dizziness or ringing in your ears, contact your doctor immediately. ### Prevention To prevent swimmer's ear, keep your ears dry and avoid inserting objects into them. Use earplugs when swimming and dry your ears thoroughly after water activities.
