Ear pain usually comes from one of a handful of common causes: an infection in the ear canal or behind the eardrum, pressure buildup from a blocked tube, or pain referred from your jaw or teeth. Most earaches resolve on their own or with simple treatment, but the type of pain, where exactly you feel it, and what makes it worse can tell you a lot about what’s going on.
Middle Ear Infections
A middle ear infection, known as otitis media, is one of the two most common causes of ear pain. It happens when fluid gets trapped behind the eardrum and bacteria or viruses start multiplying. You’ll typically feel a deep, throbbing ache inside the ear, often alongside muffled hearing and sometimes a low fever. It’s extremely common in children but can happen at any age, particularly after a cold or upper respiratory infection that causes swelling near the back of the throat.
The hallmark sign is a bulging eardrum, which a clinician can spot with a quick look inside the ear. If fluid breaks through and drains out, you may notice discharge, but the pain usually drops once that pressure releases. In children between 6 months and 2 years with only one infected ear, or in kids 2 and older with mild symptoms, guidelines support a “watchful waiting” approach: observing for two to three days before starting antibiotics, since two out of three children with mild ear infections recover without them. If pain persists or worsens after that window, antibiotics are typically the next step.
Outer Ear Infections (Swimmer’s Ear)
When the pain gets worse if you tug on your earlobe or press on the little flap at the front of your ear canal, the problem is likely in the outer ear. This type of infection, called otitis externa or swimmer’s ear, develops when water sits in the ear canal long enough for bacteria or fungi to grow. It’s common after swimming, but anything that traps moisture or scratches the canal lining (cotton swabs, earbuds, hearing aids) can set it off.
The ear canal swells and becomes tender, sometimes enough to partially close. You may notice itching first, then escalating pain, redness, and clear or yellowish drainage. Treatment usually involves prescription ear drops that reduce swelling and fight infection. To prevent it, you can use a mixture of one part white vinegar to one part rubbing alcohol dropped into each ear after swimming. The alcohol helps evaporate trapped water, while the vinegar creates an environment that discourages bacterial growth. Don’t use this mix if you already have an infection, a hole in your eardrum, or ear tubes.
Eustachian Tube Dysfunction
Your eustachian tubes are narrow passages connecting each middle ear to the back of your throat. They open briefly when you swallow or yawn to equalize air pressure and drain fluid. When they get blocked, usually from allergies, a cold, or sinus congestion, pressure builds up behind the eardrum. This causes a feeling of fullness, muffled hearing, and a dull ache that can come and go. About 3% of people who visit a doctor for ear pain have this as the primary cause.
The pain tends to spike with altitude changes. Flying, driving through mountains, or scuba diving can all make it significantly worse because the tubes can’t adjust to rapid pressure shifts. This pressure-related flare is called barotrauma. Swallowing, chewing gum, or doing a gentle forced exhale with your nose pinched (the Valsalva maneuver) can help pop the tubes open. If the dysfunction lingers for weeks, a decongestant or nasal steroid spray can reduce the swelling that’s keeping the tubes shut.
Jaw Problems and Referred Pain
Sometimes the source of ear pain isn’t in the ear at all. The jaw joint sits right in front of the ear canal, and the two share a major nerve branch called the auriculotemporal nerve. This nerve is part of the same network that serves your lower teeth, tongue, and the floor of your mouth. Problems anywhere along that network can send pain signals that your brain interprets as coming from the ear.
Temporomandibular joint (TMJ) disorders are the single most common cause of this referred ear pain. If your earache gets worse when you chew, clench your jaw, or open your mouth wide, and your hearing is normal, the jaw joint is a strong suspect. You might also notice clicking or popping when you open your mouth, tenderness along the side of your face, or a history of teeth grinding. Dental infections, wisdom teeth issues, and even throat problems can produce the same kind of referred ear pain through the same nerve pathway.
The key clue is that a doctor will look inside your ear and find nothing abnormal. Treatment targets the actual source: stress management and a bite guard for TMJ issues, or dental work for an infected tooth.
Other Common Causes
Earwax buildup is an overlooked but frequent source of discomfort. When wax gets pushed deep into the canal, often by cotton swabs, it can press against the eardrum and cause a dull ache or feeling of blockage. Over-the-counter drops designed to soften wax, followed by gentle rinsing, usually resolve it.
Sore throats, tonsillitis, and even acid reflux can produce ear pain through the same shared nerve pathways that carry jaw pain. If you’ve recently had a cold, notice pain when swallowing, or feel a burning sensation in your throat, the ear pain may be a secondary symptom rather than a standalone problem.
Changes in air pressure during flights or while driving at high elevation can cause sharp, short-lived ear pain even in people with normally functioning eustachian tubes. This is especially common during descent on a plane when you’re congested.
Managing Pain at Home
Ibuprofen is a strong first choice for ear pain because it reduces both pain and inflammation. Acetaminophen works well for pain and fever but doesn’t address swelling. For more intense pain, taking both together (alternating them on a schedule) provides better relief than either one alone. For children under 12, check with a pediatrician to get dosing based on your child’s weight.
A warm compress held against the ear can ease discomfort by relaxing the surrounding muscles and improving circulation. If you suspect fluid is trapped, sleeping with the affected ear facing down may encourage drainage. Avoid inserting anything into the ear canal, including cotton swabs, bobby pins, or ear candles, all of which risk pushing debris deeper or damaging the canal lining.
Signs That Need Prompt Attention
Most earaches don’t require emergency care, but certain symptoms signal something more serious. Swelling behind the ear, especially with redness and tenderness over the bone, can indicate that infection has spread beyond the middle ear. A fever above 102.2°F (39°C), severe or rapidly worsening pain, sudden hearing loss, dizziness, or twitching of the facial muscles all warrant prompt evaluation. Any infant younger than 6 months with a fever and ear pain should be seen right away, regardless of how mild the symptoms appear.
Bloody or pus-like discharge, particularly after a sharp pain that suddenly improves, may mean the eardrum has ruptured. While small perforations often heal on their own, they need to be confirmed and monitored.
