Causes, symptoms and treatment overview
About Outer Ear Infections
Outer ear infections, or otitis externa, occur when bacteria or fungi inflame the ear canal. Common triggers include water exposure, ear cleaning with cotton buds, skin conditions and minor trauma. Symptoms are ear pain, itching, swelling, redness and sometimes discharge or reduced hearing. Early assessment helps identify whether topical antibiotic or antifungal drops, steroid combinations, or simple pain control are appropriate. We explain treatment steps, show how to keep the ear dry, suggest measures to prevent recurrence, and advise when further medical or specialist referral is needed to protect hearing and resolve persistent infection.
