Otitis Externa in Bali – Swimmer's Ear & Surf Ear Infection
Ear pain after surfing in Canggu or Uluwatu? It may be otitis externa — an outer ear canal infection caused by trapped moisture — rather than earwax blockage. This guide covers how to tell the difference, why it happens in Bali specifically, when irrigation is safe, and when to see a doctor urgently.

What is otitis externa?
Otitis externa is an infection or inflammation of the outer ear canal — the passage between the visible outer ear and the eardrum. It is one of the most common ear conditions seen in travelers and surfers in tropical environments.
It develops when moisture becomes trapped inside the ear canal, which softens the skin lining and disrupts its natural protective barrier. Bacteria — most commonly Pseudomonas aeruginosa or Staphylococcus aureus — then grow in the warm, moist environment. In some cases, a fungal infection (otomycosis) is responsible instead.
It is also called swimmer's ear, surf ear infection, or tropical ear — all referring to the same condition in different contexts.
Otitis externa affects the outer ear canal only — it does not involve the middle ear or eardrum (unless there is a pre-existing perforation). This is why it responds well to antibiotic ear drops applied directly to the canal.
Why otitis externa is more common in Bali
Several factors in Bali create conditions where outer ear infections develop faster and more frequently than in temperate climates:
High ambient humidity — moisture in the air keeps the ear canal damp even between surf sessions, preventing it from fully drying
Warm temperatures — bacteria multiply faster in warm, moist environments
Saltwater exposure — repeated ocean immersion during surfing or snorkeling strips the ear canal's protective wax layer
Consecutive surfing days — the canal has no recovery time between sessions; inflammation from day one makes infection on day three more likely
Cotton bud use — many surfers reach for cotton buds after sessions, which removes the protective wax and can micro-abrade the canal skin
Common situations we see in Bali
Surfer · Canggu · Day 3–4 of consecutive sessions
Ear started itching after day two. By day three, one ear is painful — worse when pulling the earlobe or pressing just in front of the ear canal opening. Hearing is muffled. Initially assumed it was earwax; the otoscope shows a red, swollen canal with no visible wax impaction.
Surfer · Uluwatu / Bingin · Multiple wipeouts
Significant hold-downs and water forced deep into the ear. Ear pain and discharge appear 24–36 hours after the session. Pain increases overnight. The discharge and fever rule out simple earwax — this is otitis externa requiring antibiotic drops, not irrigation.
Swimmer · Seminyak hotel pool · Daily swimming
Chlorinated pool water has a slightly different pH that can also disrupt ear canal flora. Itching progresses to mild pain after five consecutive days of pool swimming. No surfing involved — otitis externa is not exclusive to ocean exposure.
Diver · Amed / Tulamben · Multiple dives
Equalization during descent was difficult. Post-dive, one ear feels painful and slightly wet. Pain on touching the outer ear and mild discharge the following morning. This pattern — pain rather than pressure — points to infection over earwax.
Symptoms of otitis externa — by severity
Otitis externa typically progresses through recognisable stages if untreated:
1
Mild — early irritation
Itching inside the ear canal, mild discomfort, slight feeling of fullness. No significant pain yet. Often dismissed as earwax or trapped water at this stage.
2
Moderate — developing infection
Increasing ear canal pain, especially when touching or pulling the outer ear. Muffled hearing. Possible clear or cloudy discharge. Canal beginning to swell.
3
Severe — established infection
Significant pain, swollen canal (may partially or fully close), pus discharge, possible fever. Lymph nodes around the ear may be tender. Requires prompt medical treatment.
Seek urgent care if you have: severe ear pain, fever, pus discharge, significant swelling around the ear or neck, facial weakness, or if symptoms are progressing rapidly. These may indicate a more serious infection spreading beyond the ear canal.
Otitis externa vs impacted earwax — the key differences
Both conditions cause blocked hearing and can follow ocean exposure — but the treatment is completely different, which is why correct identification matters before any procedure.
Impacted Earwax
Otitis Externa
Muffled hearing, sense of fullness
Muffled hearing + ear canal pain
Little to no pain
Pain worsens when pulling or pressing outer ear
No discharge
Clear, cloudy, or purulent discharge
No fever
Fever possible in moderate–severe cases
No swelling visible
Canal opening may appear red or swollen
Symptoms worsen with water, improve partially with jaw movements
Symptoms worsen with touch or pressure on the ear
Safe to irrigate after otoscope confirms intact eardrum
Irrigation not appropriate until infection resolves
Many surfers have both conditions simultaneously. Water entry softens and compacts earwax, while repeated moisture exposure triggers infection in the surrounding canal skin. The otoscope examination identifies which is dominant and determines the correct treatment sequence: treat the infection first, remove wax after inflammation resolves.
Why ear irrigation is not done if infection is present
This is a question we receive frequently from surfers who assumed their blocked ear just needed cleaning. Irrigation is not performed if otitis externa is present for two reasons:
Flushing an infected canal can spread bacteria deeper, potentially toward the middle ear
Water contact on inflamed skin causes significant pain and may worsen the condition
The correct sequence when both conditions are present: antibiotic ear drops (and oral antibiotics if severe) to resolve the infection first — typically 5–7 days — followed by an otoscope re-examination, and then irrigation if wax impaction remains.
Mild to moderate otitis externa responds well to treatment prescribed at a medical appointment:
Antibiotic ear drops — applied directly to the canal, typically for 5–7 days
Pain relief — anti-inflammatory medication for discomfort
Keeping the ear dry — avoiding surfing, swimming, and showering without ear protection until symptoms resolve
Avoiding cotton buds — absolutely during infection; ideally permanently after
Severe cases with significant swelling, fever, or discharge may require oral antibiotics in addition to drops. If the canal is so swollen that drops cannot reach the site, a wick may be placed to carry medication into the canal — this is assessed at the appointment.
When can I surf again after swimmer's ear?
Most patients can return to surfing 5–7 days after starting antibiotic treatment, provided pain has resolved and there is no discharge. Returning too early significantly increases the risk of recurrence. The doctor will advise on timing based on how the ear responds to treatment.
For frequent surfers, custom-fitted ear plugs are worth considering for future sessions — particularly at powerful breaks like Uluwatu and Bingin where hold-downs force water deep into the canal.
Prevention for surfers in Bali
Allow ears to dry naturally after each session before inserting anything into the canal
Tilt each ear downward after surfing and hold for 30–60 seconds to drain water
Avoid cotton buds — they remove protective earwax and abrade canal skin
Consider custom surf ear plugs if surfing daily for extended periods
Get earwax professionally cleared before a surf trip if you have known buildup
Regular professional ear cleaning (every 3–6 months for frequent surfers) removes buildup before it creates the conditions for infection, and keeps the canal clear enough for water to drain naturally after sessions.
Where to get treatment in Bali
Many surfers in Bali search for "ear infection doctor near me" or "swimmer's ear treatment Bali" when symptoms develop mid-trip. Dewa Medical provides both clinic and home visit appointments for ear examination and treatment.
Our clinic is in Kerobokan — around 10–15 minutes from Canggu and Seminyak, and 45–60 minutes from Uluwatu. For guests in Uluwatu, Ubud, or further areas, a doctor home visit brings the examination and prescription directly to your villa.

Frequently asked questions
Yes. Repeated ocean immersion during surfing traps moisture in the ear canal, strips its protective wax layer, and creates warm, moist conditions where bacteria thrive. Surfers at breaks like Canggu, Uluwatu, and Bingin who surf multiple consecutive days are particularly prone. Using cotton buds after sessions removes what remains of the protective layer and significantly increases infection risk.
The key distinguishing feature is pain. Earwax blockage causes muffled hearing and pressure but rarely causes significant pain. Otitis externa causes ear canal pain that worsens when you touch, pull, or press the outer ear. Discharge, visible redness at the canal opening, and fever are also indicators of infection. An otoscope examination at the appointment confirms which it is — and determines whether irrigation is safe to perform.
Not immediately. Flushing an infected canal can spread infection and causes significant pain on inflamed canal skin. If infection is confirmed at the examination, antibiotic ear drops are prescribed first. Once the infection has resolved — typically after 5–7 days — the ear is re-examined, and irrigation can be performed if wax impaction is also contributing to the blockage.
With antibiotic ear drops prescribed after a medical assessment, otitis externa typically improves significantly within 3–5 days. Most patients can return to surfing after 5–7 days if pain and discharge have resolved. Returning to the water too early significantly increases recurrence risk. Severe cases with significant swelling or fever may take longer and may require oral antibiotics.
