Why Are My Ears Blocked When I Have a Cold or Sinus Trouble?
Quick answer
When you have a cold, hay fever or sinus congestion, the tube that balances pressure in your ear (the Eustachian tube) gets swollen and stops working properly. That leaves your ears feeling blocked, full or muffled. It usually settles within one to two weeks. Steam, decongestants and gently popping your ears can speed things up.
Your ears and nose are connected
It surprises a lot of people, but your ears, nose and throat are all linked. A narrow channel called the Eustachian tube runs from the middle ear down to the back of your nose. Its job is to keep the air pressure behind your eardrum balanced and to drain away any fluid.
When you catch a cold or your sinuses flare up, the lining of your nose and that tube swell and fill with mucus. The tube can’t open and close as it should, and your ear pays the price.
What blocked ears feel like
This is known as Eustachian tube dysfunction – a long name for a simple problem. Typical symptoms are:
- A blocked or ‘underwater’ feeling in one or both ears
- Muffled or dull hearing
- Ears that crackle or pop when you swallow
- Mild discomfort or pressure, occasionally light dizziness
- Your own voice sounding loud or echoey
What helps it clear
The good news is that most cases get better on their own as the cold settles. To help things along, try inhaling steam from a bowl of hot water, staying well hydrated, and using a saline nasal spray to ease the congestion at the source.
Gently equalising your ears can help too: pinch your nose, close your mouth and softly blow until you feel a small pop. A short course of a decongestant or antihistamine (if hay fever is the trigger) can reduce the swelling – just check it’s suitable for you and don’t use decongestant sprays for more than a few days.
When it won’t shift
Sometimes fluid stays trapped behind the eardrum even after the cold has gone – a bit like a room that won’t air out. If your ear has been blocked for more than two to three weeks, it’s worth having it examined.
A clinician can look inside your ear and, if needed, pass a thin camera through the nose (nasal endoscopy) to see exactly what’s happening around the opening of the Eustachian tube. That helps rule out anything else and points to the right treatment.
Common questions
How long do blocked ears from a cold last?
Often one to two weeks. If it goes beyond two to three weeks, have it checked.
Will earwax removal help if the cause is a cold?
If wax is adding to the blockage, removing it helps – but congestion behind the eardrum needs the underlying cold or allergy to settle.
Can sinus problems affect my hearing?
Yes, temporarily. Once the swelling and fluid clear, hearing normally returns to normal.
Is it safe to fly with blocked ears from a cold?
It’s likely to be uncomfortable. A decongestant beforehand and frequent swallowing on descent will help.
