Ear Infection Treatment in Bangkok: Otitis Media and Swimmer’s Ear
How Doctor Bangkok diagnoses middle ear and outer ear infections and treats them the same visit.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Doctor Bangkok
Ear infection is a general term that covers two very different problems: acute otitis media, an infection of the middle ear behind the eardrum, and otitis externa (swimmer’s ear), an infection of the outer ear canal. They need different treatment. At Doctor Bangkok we examine the ear with an otoscope, identify which one you have, and prescribe the right antibiotic drops or oral course the same visit, with pain relief that works within an hour.
From the clinic: Two patients can walk in on the same morning saying their ear hurts and leave with completely different treatment. One has a bulging red eardrum from a middle ear infection that needs oral amoxicillin. The other has a swollen, tender ear canal from swimmer’s ear that needs antibiotic drops and nothing by mouth. Calling both an ear infection and treating them the same way is how resistance and treatment failures happen. The examination takes a minute and settles it.
Acute otitis media (middle ear infection)
Otitis media is an infection of the middle ear space behind the eardrum, usually following a cold when the Eustachian tube blocks and fluid traps bacteria. It is most common in children aged 6 months to 3 years but adults get it too. Symptoms include ear pain, muffled hearing, fever, and in children pulling at the ear or unusual irritability. On otoscopy the tympanic membrane looks red, bulging, and loses its normal light reflex. The American Academy of Pediatrics 2013 guideline recommends treating severe cases and children under 2 with amoxicillin, and offering watchful waiting with pain relief for mild cases in older children. Adults with a clear diagnosis are usually treated. Most cases follow a cold, so you may also want to read our page on upper respiratory infections.
| Acute otitis media (middle ear) | Otitis externa (swimmer’s ear) |
|---|---|
| Deep dull pain, worse lying down | Sharp pain when pulling the pinna |
| Often follows a cold | Often follows swimming or humidity |
| Red bulging eardrum on otoscopy | Swollen debris-filled canal |
| Muffled hearing, fever common | Itching, discharge, normal hearing |
| Oral amoxicillin first line | Ciprofloxacin ear drops first line |
| Watchful waiting possible in mild cases | Always needs topical treatment |
Otitis externa (swimmer’s ear)
Otitis externa is an infection of the external ear canal, usually from Pseudomonas or Staphylococcus, triggered by water retention after swimming, humidity, or minor trauma from cotton buds. The hallmark is tenderness when you pull on the pinna or press on the tragus, which does not hurt in otitis media. The canal looks swollen, wet and debris-filled. Treatment is topical antibiotic drops, usually ciprofloxacin or a combination with a steroid like ciprofloxacin-dexamethasone, for 7 to 10 days. Oral antibiotics are not routine and should be avoided unless the infection has spread. Keep the ear dry; no swimming until the canal settles.
How we examine and treat at Doctor Bangkok
Every ear complaint starts with otoscopy. We look at the canal, the eardrum, and its mobility where needed. For otitis media we prescribe high-dose amoxicillin as first line, amoxicillin-clavulanate if you had antibiotics in the last month or have failed amoxicillin before, and a cephalosporin or azithromycin for penicillin allergy. For otitis externa we prescribe ciprofloxacin ear drops and advise strict ear dryness. Paracetamol or ibuprofen handles pain in both, and a warm compress helps. Many patients arrive with overlapping sinus pressure or fever and we address those in the same visit.
When to see a doctor
Book an appointment for any ear pain that persists beyond 24 hours, discharge from the ear, hearing loss, or fever with ear pain. Seek same-day care for severe pain with high fever, swelling and redness of the skin behind the ear (a sign of mastoiditis), facial weakness, severe dizziness with vomiting, or any ear pain in a child under 6 months. These can reflect complications that need urgent review. Recurrent otitis media (three episodes in six months) warrants referral for tympanostomy tube consideration.
Red flag: If red-flag symptoms appear, do not wait. Book same-day or present to the nearest emergency department as described above.
Prevention and self-care
Swimmer’s ear is largely preventable by drying the ears after swimming or showering with a corner of a towel and tilting the head, and by avoiding cotton buds which strip protective wax. A 50:50 mix of isopropyl alcohol and white vinegar, two drops after swimming, helps those prone to it, but do not use it if the eardrum is perforated. For otitis media, prevention comes from handwashing, avoiding cigarette smoke, breastfeeding infants where possible, and staying current on pneumococcal (PCV) and influenza vaccination per CDC and WHO schedules. Treating allergic rhinitis with a nasal steroid also reduces Eustachian tube dysfunction.
Summary
Ear infections are not one problem but two, and the right treatment starts with an otoscope, not a phone call. Most middle ear infections in adults and older children respond quickly to amoxicillin, and most outer ear infections respond to antibiotic drops. As Dr. Pitsuwan puts it: “If pulling on the ear hurts, it is outside; if swallowing and yawning hurt, it is inside. That single test decides the prescription.” Doctor Bangkok offers same-visit otoscopy and treatment from our Sukhumvit clinic and as part of our wider 24/7 medical services.
Frequently asked questions
How can I tell if it is otitis media or swimmer’s ear?
Pain when you pull on the outer ear strongly suggests swimmer’s ear. Pain that is dull, deep and worse when lying down usually means otitis media. An otoscope examination confirms which one.
Do adults get middle ear infections?
Yes. They are less common than in children but happen, especially after a cold or during a flight. Adults usually need treatment because the diagnosis in adults is more specific than in young children.
Can an ear infection clear up on its own?
Mild otitis media in older children often does; the AAP supports a 48 to 72-hour watchful waiting approach in some cases. Swimmer’s ear does not resolve reliably without topical antibiotics.
Is it safe to fly with an ear infection?
Flying with active otitis media or a blocked Eustachian tube risks barotrauma and severe pain on descent. Postpone if you can, and if not, use a decongestant spray 30 minutes before descent.
What are the red flags in children?
Any ear pain in a baby under 6 months, high fever with ear pain, swelling behind the ear, facial droop, severe irritability, or neck stiffness needs same-day review.
Should I use cotton buds to clean my ears?
No. Cotton buds push wax deeper, strip protective oils, and cause the micro-abrasions that let swimmer’s ear take hold. Let wax move out on its own or see a clinician for removal.
