Formal audiology testing (pure tone audiometry + tympanometry) is warranted after 2 weeks. After swimming → muffled ear │ ├─ Pain when touching ear → treat as otitis externa (see doctor) │ ├─ No pain │ ├─ Feels like water sloshing → gravity + alcohol/vinegar drops │ ├─ Feels full, no slosh → check for wax (visible?) │ │ ├─ Wax seen → dry + softener after 48h │ │ └─ No wax, no slosh → possible middle ear effusion → Valsalva │ └─ Muffled + dizzy → urgent ENT (rule out fistula) │ └─ If unresolved after 72h of correct treatment → ENT exam + audiometry Final clinical pearl: Most cases of “muffled ear after swimming” are benign trapped water or swollen wax, but the one that fools people is early otitis externa – which starts with fullness before pain. If pressing the tragus hurts, stop all ear drops with alcohol or water and see a clinician. muffled ear after swimming
