Ear pain most commonly comes from an infection, either in the ear canal or behind the eardrum. But in adults especially, the source of the pain often isn’t the ear itself. Jaw problems, dental infections, and even tight neck muscles can all send pain signals to the ear, making it tricky to pin down the cause without knowing what to look for.
Ear Canal Infections (Swimmer’s Ear)
If your ear hurts more when you tug on your earlobe or press near the ear opening, you likely have an outer ear infection. This is commonly called swimmer’s ear because moisture trapped in the ear canal creates the perfect environment for bacteria. About 90% of these infections are bacterial, with the remaining 10% caused by fungus.
The pain typically spreads to the head, neck, or side of the face. You’ll probably notice a swollen ear canal, and there may be discharge or an itchy feeling before the real pain kicks in. This type of infection develops when water sits in the ear canal after swimming, showering, or even just humid weather. Using earbuds or hearing aids that trap moisture can contribute too.
Middle Ear Infections
Middle ear infections happen behind the eardrum, where fluid builds up and creates pressure. The pain tends to be deep and throbbing, and it often comes on suddenly. Unlike swimmer’s ear, pulling on the outer ear doesn’t make it worse. You might notice muffled hearing on that side, and sometimes a fever comes along with it.
This type of infection is far more common in children, often following a cold or upper respiratory infection. The tubes that drain the middle ear are shorter and more horizontal in kids, so they clog more easily. In severe cases, the pressure can cause the eardrum to tear, which actually brings sudden pain relief. While that sounds alarming, small perforations usually heal on their own within a few weeks.
Pain That Comes From Somewhere Else
Here’s what surprises most adults with ear pain: the problem often originates outside the ear entirely. This is called referred pain, and it’s actually the more common pattern in adults compared to true ear infections.
The leading culprit is jaw joint dysfunction, sometimes called TMJ or TMD. The jaw joint sits right in front of the ear canal, and when the muscles around it are tight or the joint is inflamed, the pain radiates directly into the ear. Clenching your teeth at night, chewing gum frequently, or holding tension in your jaw can all trigger this. Research on patients with jaw disorders found that pressing on the trapezius muscle in the neck, or on the chewing muscles along the jaw, frequently produced pain felt in the ear.
Dental problems are the other major source. Cavities, abscesses, and inflamed tooth roots can all send pain signals to the ear, particularly from the upper and lower back teeth. If your ear pain gets worse when you chew or drink something hot or cold, a dental issue is worth investigating.
Earwax Buildup
Impacted earwax causes a dull ache accompanied by a plugged-up feeling, ringing, and reduced hearing. It’s a different quality of pain than an infection: less sharp, more pressure. Some people also feel dizzy. The tricky part is that these symptoms overlap with other conditions, so there’s no reliable way to self-diagnose wax buildup without someone looking inside your ear.
Cotton swabs are the most common cause of impaction. They push wax deeper rather than removing it, gradually compacting it against the eardrum. If you suspect wax is the issue, over-the-counter ear drops designed to soften wax can help it work its way out naturally. Avoid sticking anything in the canal.
Pressure Changes
If your ear pain started during a flight, a drive through mountains, or after diving, the cause is a pressure imbalance across the eardrum. The eustachian tube, a small passage connecting the middle ear to the back of your throat, normally equalizes pressure every time you swallow or yawn. When this tube is swollen from a cold, allergies, or congestion, it can’t do its job, and the pressure difference stretches the eardrum painfully.
Swallowing, yawning, or gently blowing with your nose pinched shut (the Valsalva maneuver) usually opens the tube enough to relieve the pressure. If you’re congested before a flight, a decongestant taken about 30 minutes before takeoff can help keep the tube functioning. Most pressure-related ear pain resolves within a few hours once you’re back at normal altitude.
Managing the Pain at Home
Over-the-counter pain relievers like ibuprofen or acetaminophen are effective for most types of ear pain regardless of the cause. For children six months and older, either medication works. For babies under six months, only acetaminophen is recommended. A warm washcloth held against the ear can also ease discomfort while you figure out next steps.
For preventing swimmer’s ear specifically, the CDC recommends keeping ears dry after swimming or showering. Tilt your head to each side to let water drain, pull your earlobe in different directions while your ear faces down, and use a towel to dry thoroughly. A hair dryer on the lowest heat and fan setting, held several inches away, can evaporate stubborn trapped water. Ear-drying drops are available, but skip them if you have ear tubes, a perforated eardrum, or an active infection.
Signs That Need Prompt Attention
Most ear pain resolves within a few days, especially with pain management and time. But certain patterns warrant a quicker visit. Swelling behind the ear can signal a bone infection called mastoiditis. A high fever alongside ear pain, particularly in young children, points to an infection that may need treatment. And if severe pain suddenly vanishes, that can mean the eardrum has ruptured, releasing the built-up pressure.
All infants under six months with a fever or ear pain symptoms should be evaluated promptly. For older children and adults, worsening symptoms despite a few days of home care, pain that spreads to the face or neck, or any drainage from the ear are all good reasons to get checked.
