An itchy, painful ear after a morning dive at Racha Yai or an afternoon snorkel off Freedom Beach is one of the most familiar walk-ins of our week. The combination of warm sea water sitting in the canal, the constant humidity of the southwest monsoon and a holiday habit of cotton bud use creates near perfect conditions for the bacteria that cause swimmer’s ear. A ten-minute consultation tells us exactly what is in the canal and gets the right drops into you the same visit.

Why water exposure causes swimmer’s ear

Acute otitis externa is an infection of the skin lining the external ear canal, the tube between your visible outer ear and the eardrum. The canal normally protects itself with a thin slightly acidic layer of cerumen, the natural wax barrier, which discourages bacterial growth. Every prolonged swim, dive or shower washes some of that wax out and leaves moisture trapped against warm canal skin, and the local pH rises to a level that the bacteria around us thrive in. Pseudomonas aeruginosa is by far the most common cause in tropical sea and pool water, followed by Staphylococcus aureus. In patients who have already used antibiotic drops, or in chronic recurring cases, fungal organisms such as Aspergillus and Candida take over and need different treatment. Scratching an itchy canal with a cotton bud, a hairpin or a corner of a towel finishes the job, pushing wax inward, abrading the skin and removing the protective barrier in a single move.

Symptoms and how we diagnose it

The first symptom is usually itching deep inside the ear a day or two after swimming, followed by pain that worsens steadily over 24 to 48 hours. The pain is classically reproduced when you pull on the outer ear or push the small flap at the front of the canal, called the tragus, and that sign alone strongly suggests swimmer’s ear rather than a middle ear infection. Discharge starts clear and watery and may turn yellow or green as the infection establishes, hearing becomes muffled as debris and swelling block the canal, and chewing or yawning can hurt because the jaw joint sits right in front of the canal. At the clinic we use a video otoscope so you see the canal yourself on screen, which typically shows a swollen red canal full of debris, sometimes so narrow that the eardrum is hidden until we clean it. Pain on gentle tragal pressure during examination confirms the diagnosis at the bedside, no swab or imaging required for typical cases.

How we treat swimmer’s ear at the clinic

First-line treatment is a combination ear drop containing ciprofloxacin 0.3 percent and dexamethasone 0.1 percent, four drops twice daily for seven to ten days, or until three days after symptoms fully resolve. The antibiotic clears Pseudomonas and Staphylococcus, and the steroid quickly settles the canal swelling that drives the pain and blocked sensation. We dose paracetamol or ibuprofen 30 to 60 minutes before the first drops, because the drops sting less in a canal that is already comfortable. If the canal is so swollen that the drops cannot reach the eardrum, we place a small sterile sponge wick that draws the medicine inward along its length, and we remove or replace it at follow-up two days later. Fungal otitis externa, suspected when standard antibiotic drops have failed or when otoscopy shows white or black fluffy debris, is treated with clotrimazole 1 percent solution or aluminium acetate astringent drops for a longer course. Throughout treatment the ear must stay completely dry, using a plastic earplug or a cotton ball lightly coated in Vaseline during showers and no swimming whatsoever until the course is complete.

Swimmer’s ear severity and what it looks like

When to see a doctor and red flags

Most cases of swimmer’s ear settle uneventfully on drops, but a small number hide more serious problems and we screen for them at every visit. Malignant otitis externa is the one we never miss, a Pseudomonas infection that escapes the canal and erodes the bone at the base of the skull, typically in elderly, diabetic or immunocompromised patients. The clue is severe boring pain that wakes the patient at night, sometimes with granulation tissue in the canal floor and, in advanced cases, facial nerve palsy on the same side. Ramsay Hunt syndrome, caused by reactivation of the chickenpox virus in the facial nerve, presents with severe ear pain, small painful blisters in the canal or on the pinna and facial weakness, and needs antiviral treatment within 72 hours. Sudden severe vertigo, profound hearing loss, mastoid tenderness behind the ear or high fever with feeling unwell are all flags for spread of infection or an alternative diagnosis such as otitis media or cholesteatoma.

Prevention for swimmers, divers and snorkelers

Swimmer’s ear is highly preventable once you know what to do. After every swim, dive or shower, tilt the head to each side to let trapped water drain by gravity, then dry the visible part of the canal with the corner of a towel without pushing anything inside. Stop using cotton buds entirely, since they push wax and water deeper, scratch the canal skin and strip the protective layer in one stroke. Frequent swimmers and divers benefit from moulded plastic earplugs that seal the canal without trapping moisture during the dive itself. The most evidence-based home prevention, used for decades by recreational divers, is a 1 to 1 mixture of plain white vinegar and isopropyl rubbing alcohol, three or four drops in each canal after the final swim of the day. The alcohol evaporates residual water and the acetic acid restores the canal’s slightly acidic environment, which suppresses bacterial growth. Do not use vinegar drops if you know or suspect you have a perforated eardrum, and do not try to remove ear wax at home, since wax is the canal’s natural antibacterial defence, not dirt to be cleaned out.

Summary

Swimmer’s ear in Patong is an infection of the external ear canal driven by daily water exposure, warmth and humidity, and it responds reliably to combination ciprofloxacin and dexamethasone drops, simple pain relief and disciplined dry-ear precautions. Fungal cases need a different drop, malignant otitis externa is rare but lethal if missed in diabetic and elderly patients, and Ramsay Hunt syndrome is the other red-flag diagnosis behind ear pain plus facial weakness. If you have ear pain after a day in the sea, do not buy random drops over the counter, get the ear examined first so the right treatment starts on day one.

“Most swimmer’s ear in Patong is straightforward and clears in a week on the right drops if the ear is kept truly dry. What earns the ten-minute examination is the small number of cases that look like swimmer’s ear but are actually malignant otitis externa or Ramsay Hunt syndrome, and those are the cases that change a holiday into a hospital admission. We examine every ear, not just hand out drops.”

Frequently asked questions

How quickly should swimmer’s ear improve on drops?

Pain and itch usually start easing within 24 to 48 hours of starting ciprofloxacin and dexamethasone drops. Discharge and the blocked muffled feeling take longer, typically four to seven days, because canal swelling settles slowly. Complete the full seven to ten day course even if you feel back to normal, and keep up dry-ear precautions throughout, because stopping early or one accidental swim is the commonest reason the infection rebounds in the same week.

Can I keep diving or snorkelling during treatment?

No. The ear must be kept completely dry for the full seven to ten days of treatment, and divers should also wait until the canal looks fully healed before returning to depth. Diving with active otitis externa forces infected water deeper into the canal under pressure and can spread the infection toward the eardrum, and a soft inflamed canal is also more likely to bleed or scar.

Do vinegar and alcohol drops really prevent swimmer’s ear?

Yes for prevention, no for treatment. A 1 to 1 mixture of white vinegar and isopropyl alcohol used after swimming evaporates trapped water and restores the slightly acidic canal environment that suppresses Pseudomonas growth. It is endorsed by the CDC and used routinely by recreational divers. It should not be used if the eardrum is perforated or already infected, and it does not treat an established infection, only prevents one starting.

Why are cotton buds such a problem?

Cotton buds push wax and water deeper into the canal rather than removing them, abrade the skin and strip away the protective acidic wax barrier in one stroke. That is the single most reversible cause of swimmer’s ear we see. The canal is self-cleaning, and wax migrates outward on its own. Drying the visible part of the canal with the corner of a towel is the only cleaning the ear needs.

Can the clinic come to my hotel for ear treatment?

Yes. Our doctor and nurse perform video otoscopy at the bedside, prescribe and supply ciprofloxacin and dexamethasone drops, place an ear wick if the canal is too swollen for drops and provide pain relief, all at your hotel anywhere in Patong, Kalim, Kamala, Karon and Surin, day or night. WhatsApp +66 95 073 5550 to arrange a visit.

When is swimmer’s ear a medical emergency?

Facial droop on the side of the painful ear, severe boring pain that wakes you at night especially if you have diabetes or are immunocompromised, swelling and tenderness over the mastoid bone behind the ear, sudden severe vertigo or profound hearing loss, and visible blisters in the canal or on the outer ear are all red flags for malignant otitis externa, mastoiditis or Ramsay Hunt syndrome. Call us on +66 81 718 9080 and we will see you the same day and arrange hospital transfer if needed.
