What Is an Ear Infection?
Ear infections encompass two distinct conditions that are frequently confused: acute otitis media (AOM) is an infection of the middle ear space (behind the eardrum), and otitis externa is an infection of the outer ear canal — commonly called "swimmer's ear." Both cause ear pain and discomfort but have different causes, presentations, and treatments.
Acute otitis media is most commonly caused by bacteria — Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis — often following a viral upper respiratory infection that causes Eustachian tube dysfunction and fluid accumulation in the middle ear. It is the most common bacterial infection in children under 5, but adults are also affected. Otitis externa is typically caused by Pseudomonas aeruginosa or Staphylococcus aureus and is associated with water exposure, cotton swab use, or trauma to the ear canal.
our board-certified provider evaluates ear infection symptoms through detailed history-taking and clinical assessment. While a direct otoscopic view is not possible via telehealth, the distinctive symptom patterns of AOM versus otitis externa allow for accurate clinical differentiation in most cases, enabling appropriate treatment to begin without delay.
Common Symptoms of Ear Infections
Otalgia ranging from mild pressure to severe throbbing; worsened by chewing in AOM
A plugged, full sensation in the ear — particularly common in AOM with effusion
Conductive hearing loss due to fluid or inflammation blocking sound transmission
Purulent or bloody discharge from the ear canal; may indicate perforated eardrum
Fever above 100.4°F is common in acute bacterial otitis media, especially in children
In children, ear pulling, disrupted sleep, and excessive crying are key indicators
Middle ear fluid can disrupt vestibular function causing dizziness or unsteadiness

Your provider will take a thorough history including symptom duration, onset pattern, recent illnesses, and whether pain worsens with pulling on the ear (suggesting otitis externa). This clinical differentiation guides treatment selection.
For acute otitis media, first-line treatment per AAP guidelines is amoxicillin (high-dose: 80–90 mg/kg/day in children; 500 mg three times daily in adults for 7–10 days). For patients with penicillin allergy or recent amoxicillin failure, amoxicillin-clavulanate (Augmentin) is the preferred second-line agent, providing broader coverage against beta-lactamase-producing organisms. Pain is managed with ibuprofen or acetaminophen. Current guidelines support "watchful waiting" for mild AOM in healthy children over 2 years — antibiotics are not always mandatory for mild presentations, and your provider will discuss this approach during the visit.
For otitis externa (swimmer's ear), topical antibiotic ear drops are the cornerstone of treatment. Ciprofloxacin/dexamethasone (Ciprodex) or ofloxacin otic drops are highly effective. Keeping the ear dry, avoiding cotton swab use, and applying a warm compress for pain relief are important adjuncts. Oral antibiotics are rarely needed for uncomplicated swimmer's ear.
⚠️ When to Go to the Emergency Room
Most ear infections are not emergencies, but the following signs require urgent in-person evaluation:
- •Sudden or severe hearing loss — abrupt sensorineural hearing loss is a medical emergency requiring same-day audiology or ENT evaluation
- •Severe vertigo or inability to walk — vestibular dysfunction severe enough to impair balance may indicate inner ear involvement or central pathology
- •Facial weakness or paralysis — facial nerve involvement suggests severe infection spreading beyond the middle ear and requires emergency evaluation
- •Swelling, redness, or tenderness behind the ear — this triad is the hallmark of mastoiditis, a serious complication requiring hospitalization and IV antibiotics
- •Very high fever with severe headache or stiff neck — raises concern for intracranial spread or meningitis and requires emergency evaluation
