Why Ears Get Infected So Easily at My Khe and An Bang
Central Vietnam's beaches are exactly the conditions ear infections like: warm seawater, long swims, and air humid enough that a wet ear canal rarely gets a real chance to dry out before the next swim. Add a shower, a hotel pool session, or an afternoon of humidity on top of a morning at the beach, and the skin lining the ear canal stays damp for most of the day. Damp skin softens, small scratches from fingers or towels let bacteria in, and an infection can set up within a day or two of arriving.
Travellers sometimes describe this as "tropical ear" (a fair informal description of what happens in a chronically humid environment that keeps triggering the same problem, sometimes in the same ear, trip after trip. It's one of the most common reasons beach travellers in Da Nang and Hoi An end up asking for a doctor.
Swimmer's Ear vs. a Middle Ear Infection: What's the Difference?
Swimmer's ear (otitis externa) is an infection of the ear canal itself, the tube leading from the outside to the eardrum. It is usually triggered by trapped water and tends to cause pain that gets noticeably worse when you touch, tug or wiggle the outer ear, or when you push on the small flap of cartilage in front of the ear canal. The canal itself may look red or swollen, and there can be some clear or yellowish discharge.
A middle ear infection (otitis media) sits on the other side of the eardrum, in the small air-filled space behind it. It's more common in young children, often follows a cold or a blocked nose, and typically doesn't hurt more when you touch the outer ear; the pain is deeper and often comes with a general feeling of being unwell or feverish.
From the outside, the two can feel similar to the person experiencing them. The reliable way to tell them apart is an otoscope exam (a doctor looking into the canal and at the eardrum with a lighted instrument) because the two conditions are managed differently.
Children, Hotel Pools and Recurring Ear Trouble
Kids are disproportionately affected. They spend more total hours in water than adults on a beach holiday (a morning swim, an afternoon pool visit, and an evening bath), and they are more likely to rub or poke at an itchy or uncomfortable ear, which can introduce more bacteria or push wax and debris deeper into the canal.
Watch for a young child tugging or holding their ear, unusual irritability, being off their food, or trouble sleeping combined with any ear symptoms, since younger children often can't describe ear pain clearly. A brief pause from swimming, gentle drying after each swim, and prompt assessment if symptoms appear usually keeps a minor irritation from becoming a full infection that interrupts the rest of the trip.
Can I Fly with an Ear Infection or a Blocked Ear?
This is one of the most common questions we get from travellers heading home or on to another leg of their trip with ear pain. Cabin pressure changes during takeoff and landing rely on the middle ear and eustachian tube equalizing pressure smoothly; if that passage is blocked by congestion or inflamed by infection, the pressure difference can cause sharp, sometimes severe pain, and in some cases even risk to the eardrum.
Whether it's safe to fly depends on which part of the ear is affected, how blocked it feels, and how soon your flight is. If you have a flight booked and any ear pain, discharge, or a middle ear infection, the sensible step is to have a doctor examine you before you travel. If you need documentation for an airline or your itinerary, see our guide to medical certificates, sick notes and fit-to-fly letters in Vietnam for how that process works.
The Otoscope Exam: What a Doctor Actually Checks
An ear exam at your hotel is quick and doesn't require any special preparation. Using an otoscope (a handheld light with a magnifying lens), the doctor looks at the outer ear canal for redness, swelling, discharge or debris, and then at the eardrum itself to check its colour, position and whether it looks intact or perforated. This single look is usually enough to tell whether you're dealing with swimmer's ear, a middle ear infection, wax buildup, or something else entirely, such as a minor injury from a cotton bud.
Getting this exam done at the hotel rather than guessing from a pharmacy shelf matters because the two main causes of ear pain are treated differently, and using the wrong approach, particularly using the wrong drops against a perforated eardrum, can make things worse rather than better.
Ear Drops and Home Care: What's Reasonable, What Isn't
Reasonable first-line care while you arrange an assessment: gently pat the outer ear dry with a clean towel after each swim, and tilt your head to each side to let trapped water drain out naturally. That's about as far as self-care should go.
Do not put cotton buds, fingers, or any other object down the ear canal; this is one of the most common ways people injure the eardrum or push infection deeper rather than clean anything out. Do not start any ear drops on your own before an exam. Some drops that are appropriate for an ear canal infection can cause harm if the eardrum is actually perforated, and you generally can't tell the difference yourself. Once a doctor has looked in the ear with an otoscope, they can advise on and, if appropriate, provide ear drops suited to what they actually see.

- Clear visible wax or debris safely where appropriate
- Advise on and, where suitable, provide ear drops matched to the actual exam findings
- Assess whether it's advisable to fly, and provide English-language documentation for your airline or insurer if needed
- Refer on to a hospital ENT specialist for anything beyond a straightforward infection
In Da Nang, home visits typically arrive within 1 to 3 hours; in Hoi An, typically within 45 to 60 minutes.
