Many people notice a feeling of fullness or pressure in their ears when they are unwell. This is a common experience during colds, flu, sinus infections, or allergies. Understanding why ears become blocked when sick can help you manage discomfort and know when to seek professional advice. This blog explains the reasons behind blocked ears, how it happens, and what you can do to relieve symptoms safely.
What Causes Ears to Feel Blocked When Sick
When you are unwell, your ear can feel blocked due to changes in the Eustachian tube. The Eustachian tube connects the middle ear to the back of the nose and throat. It helps equalise pressure and drain fluid from the middle ear.
Common causes of ear blockage when sick include
- Eustachian tube dysfunction: Inflammation from colds, flu, or allergies can cause the tube to swell, making it harder for air to pass through and equalise pressure
- Fluid accumulation: When the tube is blocked, fluid can build up behind the eardrum, causing a feeling of fullness, pressure, or muffled hearing
- Sinus congestion: Blocked sinuses increase pressure in the head and can affect the ears
- Allergic reactions: Histamine release during allergies can increase swelling and fluid in the ear
Symptoms Associated With Blocked Ears
Blocked ears may present with several symptoms, including
- Feeling of fullness or pressure in one or both ears
- Muffled or reduced hearing
- Mild discomfort or pain
- Occasional popping or crackling sounds
Most cases improve as the underlying illness resolves.
How to Manage Ear Blockage Safely
While blocked ears are usually temporary, you can take steps to relieve discomfort
- Stay hydrated to help thin mucus
- Use saline nasal sprays to ease congestion
- Chew gum or yawn to help open the Eustachian tube
- Avoid inserting objects into the ear canal
If symptoms persist beyond a few weeks or are accompanied by severe pain, fever, or fluid discharge, seek assessment from an ear health professional such as from The Ear Nurses at Crystal Clear Ears
Conclusion
Blocked ears when sick are usually caused by temporary Eustachian tube dysfunction or fluid build-up in the middle ear. These changes are common during colds, flu, or allergies and often resolve as the illness improves. Safe management includes hydration, nasal care, and gentle pressure equalisation techniques. Persistent or severe symptoms should be assessed by a healthcare professional.
