Why Do My Ears Hurt When Scuba Diving?
Ear pain while scuba diving usually happens because water pressure increases as you descend. The pressure pushes against your eardrum, while the air inside your middle ear needs to be equalized to match the surrounding pressure.
If the pressure is not balanced, you may first feel fullness or squeezing in your ears. Continue descending and it can become painful. Forcing the descent can potentially lead to a pressure-related ear injury known as middle-ear barotrauma.
The good news is that ear pain during descent can often be avoided by equalizing early, descending slowly and never trying to push through pain.
Why Does Ear Pain Happen Underwater?
Your middle ear contains air. As you descend, increasing water pressure compresses this air and creates a pressure difference across your eardrum.
Your Eustachian tubes connect the middle ears with the back of your throat. When you equalize, these tubes allow air to enter the middle ear and balance the pressure.
Problems usually happen for one of three simple reasons:
This is also why ear discomfort can appear surprisingly close to the surface. You don’t need to be on a deep dive before pressure becomes important.
How Do You Stop Your Ears From Hurting While Diving?
The most important rule is simple: Don’t wait for pain before you equalize.
Start equalizing at the surface and continue regularly as you descend. Many divers pinch their nose through the mask and gently blow against their closed nostrils. Swallowing or moving the jaw can also help some divers.
The process should feel gentle. You shouldn’t need to blow extremely hard to make your ears clear.
What to Do When Your Ears Feel Pressure

Diving when you cannot equalize normally |
If you still cannot equalize, don’t force yourself deeper.
Going back up is always better than turning a small equalization problem into an ear injury.
Why Won’t One Ear Equalize?
Sometimes one ear clears easily while the other refuses to cooperate.
This doesn’t necessarily mean anything is seriously wrong. One Eustachian tube may simply open more easily than the other, and congestion or irritation can also affect each side differently.
The same principle still applies.
Stop your descent and move slightly shallower. Give yourself time, breathe normally and try gently again.
What you shouldn’t do is continue descending while repeatedly blowing harder.
If the ear will not equalize comfortably, end the descent.
Should You Dive With a Cold or Blocked Nose?
A mild cold may not seem like a big problem on land, but congestion can make equalizing much more difficult underwater.
If your nose or sinuses are blocked and you cannot equalize normally, it is better to skip the dive.
Don’t rely on medication simply to make a dive possible without appropriate medical advice. If you regularly have trouble equalizing or have an existing ear condition, speak with a medical professional familiar with diving medicine.
There will always be another dive.
What Happens If You Keep Diving With Ear Pain?
Ear pain is not something you should try to tolerate.
Continuing deeper while your ears cannot equalize increases the pressure difference across the eardrum. In more serious cases, this can cause middle-ear barotrauma, which may result in pain, fullness, reduced hearing or other symptoms.
This is why instructors teach divers to communicate ear problems rather than hide them.
If something hurts, stop.
You are not delaying the group or failing the dive. You are responding correctly to what your body is telling you.
Why Beginners Often Have More Trouble With Their Ears
Equalizing sounds easy when explained on land.
Underwater, a new diver is thinking about much more than their ears.
You’re breathing through a regulator, watching your instructor, controlling your position, checking your depth and trying to remember everything you learned during the briefing.
It is easy to descend another metre without realizing that you haven’t equalized.
With experience, the process usually becomes much more automatic. You learn to equalize before discomfort starts and become more comfortable stopping your descent whenever you need extra time.
This is also why beginner dives should never be rushed. Your instructor can wait, adjust the descent and help you become comfortable before going deeper.
My Ears Feel Blocked After Diving. Should I Worry?
A feeling of fullness or a blocked ear after diving can sometimes occur following difficulty equalizing.
What matters is whether the symptoms improve.
Persistent pain, noticeable hearing changes, ringing, bleeding or discharge should be medically evaluated. Dizziness or vertigo after diving also deserves prompt medical attention.
Avoid trying to diagnose the exact problem yourself, especially if the symptoms are significant or getting worse.
Make Equalizing Part of Your Descent
Experienced divers don’t necessarily have ears that are better suited to diving. Often, they have simply developed better habits.
They equalize before pain starts. They descend at a pace that works for them. And if an ear does not clear, they stop rather than forcing it.
Remember the simple sequence:
Equalize early → descend slowly → equalize often → stop if it hurts.
Once that becomes automatic, you will probably spend far less time thinking about your ears and much more time enjoying the dive.
