Ear infection in adults: symptoms, treatment, and when to worry

Often not right away. Guidelines support watchful waiting for 48 to 72 hours for mild middle ear infections in healthy adults, because many are viral or clear on their own. Antibiotics, usually amoxicillin, enter the picture when symptoms are severe from the start (moderate or worse pain, fever of 39 C / 102.2 F or higher), when symptoms are not improving after two to three days, or when the eardrum has perforated with drainage. Swimmer's ear, an infection of the ear canal rather than the middle ear, is different: it is treated with antibiotic ear drops, not pills, and keeping the ear dry. Pain control matters either way: acetaminophen or ibuprofen handles the pain while the infection runs its course, and that is safe to start immediately.

The pain of an acute middle ear infection typically peaks within the first two to three days and improves over about a week. A feeling of fullness or muffled hearing can linger for two to six weeks after the infection itself clears, because fluid behind the eardrum drains slowly; that lingering fullness alone is not a sign the infection is still active. Symptoms that are not improving at all after three days, pain that gets worse after starting to improve, or any episode lasting beyond two weeks deserves re-evaluation. Recurrent ear infections in an adult, meaning several within a year, are uncommon enough that they warrant a proper workup rather than repeated courses of the same antibiotic.

Yes, but almost always temporarily. Fluid and pressure behind the eardrum muffle hearing during the infection, like listening underwater, and hearing returns as the fluid drains over the following weeks. Lasting hearing loss from a simple ear infection is rare in adults. The exceptions that justify prompt attention: hearing that stays muffled beyond about six weeks after the infection, sudden complete hearing loss in one ear (a same-day emergency regardless of infection), or drainage of blood or pus from the ear. Recurrent infections with fluid that never fully clears can also gradually affect hearing and are a reason for an ear, nose, and throat referral rather than another round of home care.

Ear pain responds well to simple measures. Acetaminophen or ibuprofen, taken on schedule rather than waiting for pain to spike, is the backbone and is safe for most adults. A warm compress held against the ear helps many people; some prefer cold, and either is fine. Sleep with your head slightly raised, since lying flat increases pressure in the middle ear. Swallowing, yawning, and chewing gum help the eustachian tube open and drain pressure. Do not put anything inside the ear canal: no cotton swabs, no ear candles, and no drops unless a clinician has recommended them, because a perforated eardrum changes what is safe to put in the ear. If pain defeats all of these measures, that itself is a reason to get seen.

Get same-day care for severe or worsening pain, fever of 39 C (102.2 F) or higher, swelling, redness, or tenderness behind the ear or the ear pushing outward, a stiff neck, severe headache, facial weakness or drooping, dizziness that makes walking straight impossible, confusion, or drainage of blood or pus. Those signs raise concern for the infection spreading to the bone behind the ear or beyond, which is rare but dangerous. Sudden hearing loss in one ear is always same-day. Also take recurrence seriously: several ear infections in a year as an adult is unusual and warrants an ear, nose, and throat evaluation for an underlying cause, from chronic sinus disease to, rarely, something blocking the eustachian tube.

They are infections in different places and they feel different. A middle ear infection sits behind the eardrum, usually follows a cold, and produces deep pressure-type pain, muffled hearing, and sometimes fever; pulling on the outer ear does not change the pain. Swimmer's ear is an infection of the ear canal itself, often after water exposure or cotton swab use, and the giveaway is pain that gets sharply worse when you tug the earlobe or press the small flap in front of the canal, sometimes with itchiness and drainage. Treatment differs too: middle ear infections are managed with pain control and sometimes oral antibiotics, while swimmer's ear is treated with ear drops and keeping the canal dry. Telling them apart takes about a minute in a consult.
