The plane landed at Samui airport hours ago, but your ear still feels like it is stuffed with cotton. Or maybe it was the descent on yesterday’s dive that did it. Blocked ears after flying or diving are one of the most common walk-in complaints at our Chaweng clinic, and the right fix depends entirely on the cause.
Most blocked ears are harmless pressure and clear on their own. Some are wax that needs removing. A few are the start of an infection that should not wait, especially if you are flying home soon. Here is how to tell which one you have, and what to do about each.
Pressure, Wax, or Infection: The Three Usual Suspects
Pressure blockage happens when the eustachian tube cannot balance the air behind your eardrum during descent. The ear feels full and hearing sounds distant, but there is little or no pain, and it slowly improves over hours. Wax blockage feels similar but does not improve, because a plug of wax is physically sitting against the eardrum, often shoved there by cotton buds or squeezed tight by pressure changes. Infection is different: the fullness comes with growing pain, and sometimes fever, discharge, or dizziness.
Time is a useful test. Pressure improves day by day. Wax stays exactly the same until someone removes it. Infection gets worse. If your blocked ear is heading downhill, with more pain today than yesterday, stop waiting for it to fix itself and get it looked at.
Safe Ways to Clear Blocked Ears (and What to Skip)
For pressure, work with your body. Swallow often, chew gum, yawn widely, or suck on a sweet. Try a gentle Valsalva: pinch your nose, close your mouth, and blow softly until the ear clicks. Softly is the key word, because hard blowing can hurt the eardrum. Steam from a hot shower helps some people, and staying well hydrated keeps the tube working. Most pressure blockages fade within a day or two, and often much sooner than that.
Now the skip list. Do not push cotton buds into the canal; they compact wax and scratch the skin. Do not try ear candles, which do nothing and cause burns. Do not pour random drops into a painful ear, because if the eardrum has a tear, some drops are harmful. And do not go diving again until the ear is fully clear.
When Blocked Ears Need a Clinic Visit
Come in if the blockage lasts more than two or three days, if there is pain, fever, discharge, dizziness, or real hearing loss, or if you have a flight or dive booked and the ear is not right. Wax removal at a clinic is quick and painless, and it often restores hearing instantly. If it is an infection, starting treatment early usually means you are well before your flight home. Never board a plane with severe ear pain before a doctor has checked the ear.

Frequently Asked Questions
How long should ears stay blocked after a flight?
Simple pressure blockage usually clears within a few hours, and almost always within a day or two. If your ear is still blocked after two or three days, or it starts to hurt, something else is going on, most often wax or fluid. That deserves a quick look with an otoscope rather than more waiting.
Can I dive with a blocked ear?
No. A blocked ear cannot equalize, and descending on it risks real damage to the eardrum. Get the cause sorted first. If it is wax, removal takes minutes and you may be cleared quickly. If it is an infection, diving must wait until a doctor says the ear has healed.
Do ear candles work?
No. Studies show they do not remove wax, and clinics regularly see burns and candle wax deposited in the canal instead. If wax is the problem, professional removal is quick, safe, and actually works. It is one of the most satisfying five-minute fixes in all of medicine.
Can you remove ear wax at Doctor Samui?
Yes, at any time of day or night. Our doctors check the ear first with an otoscope to confirm wax really is the problem, then remove it gently and safely. Many travelers hear clearly again before they leave the clinic. You get a free quote on WhatsApp or a quote before treatment at the desk.
My ear is blocked and painful and I fly home tomorrow. What should I do?
Come in tonight rather than gambling on the flight. Cabin pressure on an inflamed ear can be severely painful and can damage the eardrum. A doctor can often treat the problem or make flying safer, and will tell you honestly if the flight should wait. We are open 24 hours for exactly this situation.
