Ear pain during a cold is most often caused by Eustachian tube dysfunction, where cold-related inflammation blocks the tube that normally drains the middle ear, causing pressure to build behind the eardrum. ChatRx can review symptoms chat-based in Indiana, Illinois, and Michigan for $25 flat and either treat a middle ear infection with antibiotics if warranted or steer you to in-person care when the exam suggests something more.
Ear pain shows up during colds more often than most adults expect. The mechanism is straightforward once you know what’s happening in your head. Here’s what causes it, when it means you also have an ear infection, and what to do about it.
What’s Happening Behind the Eardrum
Your middle ear (the space behind the eardrum) connects to the back of your throat through a small passage called the Eustachian tube. Its main jobs are equalizing pressure and draining any fluid that accumulates in the middle ear.
When you get a cold, the same viral inflammation that causes runny nose and congestion also affects the Eustachian tube. The tube swells and stops working normally. When that happens, pressure changes can’t equalize, and fluid can start to build up in the middle ear, creating that fullness, pressure, and sometimes stabbing pain.
That’s Eustachian tube dysfunction, and it accounts for most cold-related ear pain in adults.
Eustachian Tube Dysfunction vs Middle Ear Infection
The two often blur into each other, and one can lead to the other.
Eustachian tube dysfunction causes a feeling of ear fullness or pressure, muffled hearing, popping or crackling, sometimes discomfort or mild pain. Symptoms usually resolve as the cold resolves. Antibiotics don’t help because there’s no infection.
Middle ear infection (otitis media) develops when fluid trapped in the middle ear gets colonized by bacteria. Pain often becomes sharper and more intense. Fever may develop. Hearing changes worsen. In severe cases, the eardrum can rupture, releasing pus and providing sudden pain relief. Antibiotics often help.
The general timeline: Eustachian tube dysfunction can start early in a cold and get worse over a few days. If it progresses to a true bacterial middle ear infection, symptoms usually get significantly worse rather than better around day 5 to 7 of the cold.
Yes. Eustachian tube dysfunction and ear infections often affect just one side, especially if congestion is worse in one nostril. Both ears being affected isn’t dangerous on its own, but it does lower the threshold for getting checked out.
Both work through the same mechanism, Eustachian tube swelling, but allergies tend to be longer-lasting and come with itchy eyes or sneezing rather than a sore throat or fever. If your “cold” symptoms show up the same time every year, allergies are worth considering.
Why Adults Get this Too
Ear infections are typically associated with kids, but adults get them too. About 20% of adults will have at least one middle ear infection in their lifetime, and Eustachian tube dysfunction happens even more commonly.
Adults are less likely than kids to develop full middle ear infections because our Eustachian tubes are longer and more angled, which helps them drain better. The mechanism is the same though.
Certain factors increase adult ear-related complications during colds. Smoking or vaping increases the risk, as does a history of sinusitis or allergies. Recent air travel with congestion can compound the problem. Being immunocompromised or having underlying anatomical issues like a deviated septum also raises the risk.
What Helps at Home
For most cases of cold-related ear pain, home care manages the symptoms while the cold resolves.
Over-the-counter pain relievers (acetaminophen or ibuprofen) address both the pain and any inflammation. Warm compresses on the outside of the ear can soothe discomfort. Nasal decongestants (used briefly, not for more than 3 days for the nasal sprays) reduce swelling in the passages connected to the Eustachian tube.
The “Valsalva maneuver” (pinching your nose and gently trying to blow through it while keeping your mouth closed) can help pop the ears open. Do this gently. Forceful attempts can cause damage.
Yawning, swallowing, chewing gum, and drinking fluids also help the Eustachian tubes open. Stay well hydrated.
Skip decongestants if you have high blood pressure or heart conditions without talking to a doctor first.
When to See a Doctor
See a doctor when ear pain is severe, persistent, or worsening after several days. Drainage or discharge from the ear canal warrants evaluation, as does significant or persistent hearing loss. A fever of 101°F or higher alongside ear pain is another sign, along with symptoms that improve then dramatically worsen (suggesting a bacterial infection has developed). Both ears being affected, or ear pain in someone with a compromised immune system, also lowers the threshold for evaluation.
Head to the ER for any severe swelling around the ear, high fever with confusion, stiff neck, or facial weakness on the affected side. These are rare but signal potentially serious complications.
For infants and young children with ear pain and fever, same-day evaluation is warranted.
Where ChatRx Fits
ChatRx treats ear infections and upper respiratory infections as part of our 39 acute conditions. If you’re in Indiana, Illinois, or Michigan and dealing with cold-related ear pain that fits the pattern of a middle ear infection, our doctors can review the case chat-based and prescribe antibiotics when appropriate. Chat-based, $25 flat.
For severe symptoms, hearing loss, facial swelling, or signs of complication, our doctors will steer you to in-person care since a physical ear exam and sometimes imaging may be needed. The free symptom checker can also help sort what to do. No account required.
Quick Take
Ear pain during a cold is usually Eustachian tube dysfunction rather than a full bacterial ear infection. It happens because cold-related inflammation blocks the tube that normally drains the middle ear. Most cases resolve as the cold resolves within a week or two with pain relievers, decongestants, and time. See a doctor when pain is severe, worsening after a few days, comes with fever, or comes with drainage. And skip the antibiotics unless a doctor confirms a bacterial infection is present.
