What to do if you cannot equalize during a dive

The first response is simple: stop going down. Keep your breathing steady, hold position or use a descent line if available, and give yourself room to think. A failed equalization is not a test of toughness. The pressure difference may be small, but forcing against a blocked Eustachian tube can turn discomfort into an ear injury.

Signal your buddy or guide with the agreed problem signal. Move a little shallower, not necessarily all the way to the surface, until the pressure eases. Then try a gentle equalization using the technique you have been taught; do not blow hard, repeatedly strain or continue if there is pain. If it does not work promptly, abandon the descent. A calm, controlled end to a dive is a successful safety decision.

DAN advises divers to equalize early and often, and its guidance says to stop if it hurts and ascend a few feet before trying again. This is prevention, not a target depth or a promise that every technique suits every ear. The numeric rule is useful as a rhythm, not a quota: DAN notes that most authorities recommend equalizing every 2 feet of descent.

Knowing when to stop trying to equalize your ears while diving protects judgement as much as it protects your ears. Stop immediately when you feel pain, a strong one-sided block, increasing pressure, a sudden loss of hearing, ringing, fluid, bleeding or dizziness. A mild sensation that improves after moving shallower is different from pain that returns every time you descend; either way, do not use repeated force to win the argument with your ear.

Do not confuse an equalization problem with a mask issue, a flooded nose or anxiety. Check your position and mask fit only if you can do so without descending, and keep your buddy informed. Looking slightly up and descending feet-first may make equalization easier for some divers, while a line can help control the rate. These are training options, not emergency treatment or a reason to ignore symptoms.

If you are unable to equalize at the surface before entry, or you are congested, unwell or recovering from an ear or sinus problem, tell the professional leading the dive and reconsider entering. Do not self-medicate to make a dive happen without appropriate medical advice. Ear anatomy, medication effects and past injuries differ, so a doctor familiar with diving medicine is the right person to assess fitness when there is uncertainty.

Once you are safely out of the water, write down the useful details while they are fresh: which ear was affected, at what stage of descent, whether pain improved when you ascended, which technique you tried, and whether symptoms continued afterwards. Tell the dive operator or instructor. This record can help a clinician assess possible barotrauma and prevents you forgetting a warning sign before your next booking.

Persistent pain, blocked hearing, tinnitus, discharge, bleeding, imbalance or vertigo deserves prompt medical assessment. Seek urgent local care for severe or worsening symptoms. Do not put drops, cotton buds or other objects in an ear that may be injured, and do not assume that a normal-looking outer ear means the middle or inner ear is fine. This article is general information, not a diagnosis; a clinician decides what examination or treatment is appropriate.

Returning to diving should be a decision based on recovery and professional advice, not on a calendar countdown. If your ears still feel blocked, do not make a shallow recreational dive as a test. Discuss the incident with a qualified dive professional after medical advice, particularly if the episode involved vertigo or hearing change. For related context, read what to do when you cannot equalize while diving and what if my ears hurt and I cannot descend while diving.

Preparation starts before you board. During the briefing, tell the instructor or guide that equalization has been difficult and agree on a clear signal for “stop” and “ascend”. Check that you can comfortably equalize on the surface without force. Plan a slow, feet-first descent in a position where you can pause, and use a mooring or descent line when the site and conditions allow. A line is especially helpful in Hong Kong’s changing visibility or current because it lets you control movement rather than drift down faster than intended.

Begin early and repeat gently, before discomfort appears. DAN recommends staying ahead of the pressure rather than waiting for a painful squeeze. Relax your jaw, swallow and use only a familiar method taught in your course. If a mask fill, cold water or stress makes you tense, pause and regain control. Equalization is not a competition with the other divers in your group, and a planned turnaround is better than rushing to catch up.

Review likely contributors between dives: a recent cold, allergy symptoms, smoking exposure, alcohol, dehydration, poor sleep, or a technique you have not practised. These do not provide a diagnosis, but they are sensible prompts for an honest go/no-go conversation. If you need medical advice about another health circumstance, such as scuba diving during pregnancy medical advice, use a clinician rather than a forum or a friend’s experience.

The right choice depends on symptoms, communication and whether pressure becomes comfortable when you move shallower. The table below is a decision aid, not a substitute for your training agency’s procedures or medical care. In every option, stay with the plan, maintain your normal breathing and tell your buddy or guide what is happening.

A guide may suggest a different site or a surface interval later, but no operator can guarantee that a future attempt will be comfortable. If your concern is broader than equalization, how to compare dive insurance with a medical declaration may help you prepare questions about disclosure and cover.

A stopped descent gives you useful information: the depth, rate, position, symptoms and whether a small ascent helped. Share that record before booking another dive. An instructor can observe your surface preparation and descent communication, while a diving-medicine clinician can address persistent or unusual symptoms. Neither should pressure you to continue when your ears are warning you.

If a previous episode included ringing or dizziness, do not rely on guesswork about recovery. Read when can I dive again after tinnitus or vertigo and obtain individual advice. The goal is not to find a trick that defeats pain; it is to make a clear decision early enough that you finish the day well and preserve confidence for future diving.

Use this three-part check before the next entry: can I equalize gently before descent, can I communicate and stop without embarrassment, and do I have a plan if symptoms remain? If any answer is no, postpone and ask for help.
