How to tell the difference between barotrauma, earwax blockage, and infection.
Ear pain after scuba diving, freediving, or snorkeling in Bali is common — and can have several different causes. Barotrauma from equalisation pressure, impacted earwax compacted by depth, and outer ear infection from water exposure each require different treatment. Getting the diagnosis right matters.
Many divers assume their ear problems are always barotrauma. In practice, a significant proportion of post-dive ear blockage in Bali is caused by pre-existing earwax compacted by the pressure of descent — particularly in surfers and regular swimmers who already had borderline wax buildup before their dive trip.
Depth pressure forces water into the canal: at even 5–10 metres, water pressure pushes ocean water against pre-existing wax, compacting it further toward the eardrum.
Wax absorbs saltwater: cerumen absorbs moisture on contact, causing it to swell and expand — a mild blockage before the dive can become a complete impaction by the time the diver surfaces.
Narrowed canals make this worse: divers with exostosis (bony narrowing from repeated water and cold exposure) are particularly prone to wax compaction because the narrower canal traps wax more readily.
Equalisation becomes harder: when wax is pressing against the eardrum, the eardrum cannot move as freely, making both Valsalva and Frenzel equalisation more difficult — which is sometimes mistaken for Eustachian tube dysfunction.
If your equalisation was harder this trip than previous trips to the same dive site, earwax buildup is one of the first things to check. Pre-dive earwax removal can restore normal equalisation and reduce barotrauma risk on future dives.
Can earwax increase barotrauma risk?
Yes — and this connection is underappreciated by both divers and general practitioners.
Barotrauma occurs when the pressure difference between the middle ear and the external environment cannot be equalised fast enough during descent. The eardrum is squeezed inward by the increasing external pressure. If the outer ear canal is also partially blocked by impacted wax, the external pressure on the eardrum is partly trapped — creating a squeeze from both sides simultaneously.
This is why some divers who equalise without difficulty in clear conditions suddenly find it painful and difficult after a week of daily ocean swimming: the wax accumulated during that week has changed the dynamics of pressure transmission through the canal. Removing the earwax before the next dive often resolves the equalisation difficulty immediately.
When to stop diving immediately
These symptoms during or immediately after a dive require stopping all diving and seeking medical assessment before returning to the water:
Dizziness or vertigo underwater: can indicate inner ear barotrauma or perilymph fistula — a rupture of the membrane separating the inner and middle ear. Requires urgent assessment.
Sudden complete hearing loss in one ear: after any dive, this is a medical emergency. Do not dive again until evaluated.
Blood or fluid from the ear canal: suggests eardrum rupture. Stop diving immediately.
Severe ear pain that does not resolve within an hour of surfacing: significant barotrauma or middle ear involvement requiring examination.
Facial numbness or weakness: rare but serious — requires urgent care.
If you have any of these symptoms after diving, do not continue diving and do not fly. Contact a doctor immediately. WhatsApp us for urgent assessment →
When NOT to fly after a diving ear injury
This question comes up constantly among divers in Bali who have a flight home in the days following their dive trip. The general guidance from dive medicine:
Simple earwax blockage (no barotrauma): flying is possible once the earwax has been removed and the ear canal feels clear. Remove the wax before the flight, not on the day — allow a few hours for the canal to settle.
Mild barotrauma (grade 1–2): a minimum of 24–48 hours surface interval before flying is recommended, assuming symptoms are improving. If there is still pain or hearing loss at 48 hours, extend the interval.
Moderate to severe barotrauma (grade 3+) or suspected eardrum rupture: do not fly until cleared by a doctor. Flying with a ruptured eardrum risks middle ear infection and further injury from cabin pressure changes.
Inner ear barotrauma or vertigo: do not fly until specifically cleared. This is a serious injury requiring extended rest and medical assessment.
Flying too soon after a diving ear injury is one of the most common causes of long-term ear problems in divers. If you are unsure, book an examination before your departure. Pre-departure ear check → Earwax Removal Before Flying
Common situations we see in Bali
These are the most frequent scenarios patients describe when they contact us:
Scuba diver · Amed / Tulamben
Equalisation was difficult during the descent. Post-dive, one ear feels painful and slightly wet. Pain worsens when pulling the outer ear — this pattern suggests otitis externa developing alongside the pressure issue, not barotrauma alone.
Freediver · Nusa Penida
Deep breath-hold dive, significant pressure sensation on descent. Ear still feels full and muffled 48 hours post-dive. Muffled hearing without significant pain is consistent with earwax compacted by depth pressure — not barotrauma.
Snorkeler · Gili Islands
Surface snorkeling, no significant depth. One ear blocked after the session, sensation persists into the next day. No depth pressure involved — this is almost certainly earwax swollen by water entry.
Regular diver · Returning to Amed after a break
Dived fine previously, now equalisation is harder and wax buildup is accumulating more each trip. This is consistent with exostosis progression — the canal narrowing over time from repeated water and pressure exposure.

What to do — and what to avoid
Do not dive with a blocked ear: Diving with an unresolved ear blockage significantly increases barotrauma risk. Get the ear examined and cleared before your next dive.
Do not force equalisation: If equalisation is painful or difficult, ascend slightly and try again gently. Forcing it can rupture the eardrum.
Avoid cotton buds post-dive: Cotton buds remove protective earwax and abrade canal skin, increasing infection risk after water exposure.
See a doctor before your next dive: Whether the cause is wax, infection, or barotrauma — a medical assessment ensures it is safe to continue diving.
Seek urgent care if you have: severe ear pain, fever, discharge from the ear, sudden complete hearing loss, or dizziness with vomiting. These may indicate infection rather than simple earwax blockage.

Frequently asked questions
The most common causes are: barotrauma (pressure injury from failed equalisation during descent), outer ear infection (otitis externa from water trapped in the canal), and earwax compacted by depth pressure. Each has different symptoms and treatment. An otoscope examination quickly identifies which it is — and only then is the appropriate treatment decided.
Barotrauma typically causes pain during descent, a sensation of fullness, and sometimes blood or fluid from the ear. Earwax-related blockage develops more gradually, causes muffled hearing and pressure, and is often worsened by water entry. Significant pain when touching the outer ear suggests infection. A doctor can distinguish between these within minutes of examination.
Not until the cause has been identified. Diving with an ear infection risks spreading the infection. Diving with unresolved barotrauma risks eardrum rupture. Earwax blockage makes equalisation harder, increasing injury risk. Always get a medical assessment before returning to the water.
