Blocked ears are a common and often uncomfortable symptom of colds and flu. This article explores why ear congestion happens during a respiratory infection, how to relieve the pressure, which treatments work best—including medications and home remedies—and what to do if the problem doesn’t go away.
Blocked ears are a common symptom during or after a cold or flu, and often occur alongside congestion, coughing, sore throat and sinus pressure. When they become blocked due to mucus or swelling, the ear can feel full, muffled, or even painful. Many people experience a blocked ear from a cold during the acute phase of the illness, especially when nasal congestion is present. This is often described as a blocked ear after a cold, and may affect one or both ears. It is also common to report ringing in the ears, pressure, or a sensation of “popping” when swallowing or yawning. Symptoms can vary in intensity, and may worsen when lying down or during changes in altitude (e.g. flying or driving in the mountains).
People may ask, “Is it normal to get blocked ears with a cold?” The answer is yes—ear blockage is a frequent and typically benign consequence of upper respiratory infections. However, if ear pain becomes severe, hearing is significantly reduced, or the blockage lasts longer than expected, it is advisable to consult a healthcare professional to rule out secondary complications such as otitis media or Eustachian tube dysfunction.
The primary cause of blocked ears during a cold lies in the inflammation and mucus production associated with upper respiratory tract infections. When the body responds to viral infection, the tissues lining the Eustachian tubes can swell and block airflow to the middle ear. At the same time, excess mucus can become trapped within the sinuses and back of the throat, further obstructing the passageways that help regulate ear pressure.
This dysfunction can result in a vacuum-like effect within the middle ear, making it difficult to hear normally and often producing sensations of pressure or popping. While the immune system works to clear the infection, this temporary blockage typically improves on its own. However, if inflammation persists longer than the cold itself, or if the mucus fails to drain effectively, symptoms such as a blocked or painful ear can remain for some time. This explains why many people report a blocked ear even after the flu or cold has otherwise resolved.

When dealing with ear pain caused by a cold, a combination of pharmaceutical and home remedies can provide effective relief. In the following sections, we will explore various strategies for alleviating ear pain, from simple, natural approaches to over-the-counter treatments. These remedies are particularly useful for pain linked to congestion and inflammation. By using a warm compress, over-the-counter pain medications, or saline nasal sprays, you can ease the discomfort associated with blocked ears. However, if the pain intensifies or becomes sharp and persistent, it may be necessary to seek medical advice to rule out more serious conditions, such as otitis media. Let's explore these remedies in more detail to help you manage the discomfort and speed up your recovery.

Many individuals prefer to explore natural or home-based options for earache relief, particularly in the early stages of a cold. Steam inhalation, using either plain hot water or with the addition of essential oils such as eucalyptus, can help ease sinus congestion and support middle ear drainage. Gentle massage of the neck and jaw area may encourage lymphatic flow and reduce fluid build-up around the ear canal.
Keeping the head slightly elevated during rest or sleep can also prevent fluid from accumulating in the Eustachian tubes overnight.. While they may not resolve all cases, they can provide comfort and support the healing process alongside other treatments.
Children are particularly susceptible to blocked ears during respiratory illnesses due to the structure of their Eustachian tubes, which are shorter and more horizontal than in adults. This anatomical difference makes it easier for mucus and inflammation to interfere with proper ear drainage. As a result, children may experience a feeling of fullness in the ears, reduced hearing, or even develop middle ear infections.
In younger children, symptoms may be harder to recognise, but changes in behaviour such as irritability, crying more than usual, or tugging at the ear can all indicate discomfort. While most cases resolve without complications, it is important for parents to monitor the situation, especially if symptoms last longer than a few days or if the child develops a fever or fluid discharge. A GP or paediatrician should evaluate any signs of infection to ensure timely and appropriate treatment.
For some individuals, blocked ears persist long after a cold has subsided. If your ear remains blocked for more than a week or two following a cold, this could indicate ongoing inflammation in the Eustachian tubes, fluid accumulation in the middle ear, or even the development of a secondary infection. Many people who experience a blocked ear for an extended period after a cold, such as for two to three weeks, often seek information about why their ear won't unblock. This lingering sensation can be a sign of ongoing inflammation or other complications, which is why it's not uncommon for individuals to search for answers regarding their prolonged symptoms.
When the blockage continues, it is important to consult with a healthcare professional to determine the underlying cause. In some cases, persistent Eustachian tube dysfunction may require further treatment or a referral to an ear, nose, and throat (ENT) specialist. This is especially crucial if the blockage is affecting hearing, causing significant discomfort, or if other symptoms, such as pain or fluid drainage, are present.
The time it takes for ears to unblock after a cold can vary depending on the individual and the severity of the congestion. For most people, symptoms improve within a few days as the inflammation in the upper airways begins to subside. In moderate cases, it may take one to two weeks for full resolution.
However, if the blocked sensation continues for two to three weeks or more, or if symptoms appear to be getting worse rather than improving, further medical assessment may be necessary. While most cases are benign, persistent blockage should not be ignored.
Flying while experiencing a cold can worsen ear blockage and lead to ear pain during flight due to the rapid changes in cabin pressure during take-off and landing. This issue is especially problematic if the nasal passages are congested, as it becomes difficult for the ears to equalise pressure effectively.
For travellers who must fly while unwell, using a nasal decongestant before the flight, practising the Valsalva manoeuvre during descent, and staying well-hydrated can help reduce discomfort and alleviate ear pain during the flight.
Some travellers also use filtered earplugs designed to gradually regulate air pressure, providing additional protection during the flight. If the ears remain blocked after flying with a cold, recovery may take longer than usual, and symptoms should be carefully monitored in the days following the flight.
When ears feel blocked in the absence of cold or flu symptoms, the underlying cause is often different from the typical congestion associated with respiratory illnesses. Common reasons for blocked ears without a cold include earwax impaction, allergic rhinitis, barotrauma (pressure changes), or temporomandibular joint dysfunction. In some cases, muscle tension or anxiety, particularly around the neck and jaw area, can also lead to a feeling of fullness or discomfort in the ears. If the sensation persists or worsens, it's advisable to seek medical advice to identify the specific cause and determine the appropriate treatment.
