Ear pain has dozens of possible causes, ranging from a simple buildup of earwax to infections, pressure changes, and problems that don’t actually start in the ear at all. The source of the pain often depends on where exactly you feel it, what makes it worse, and whether other symptoms like fever or hearing changes come along with it.
Middle Ear Infections
A middle ear infection is one of the most common reasons for ear pain, especially in children. It happens when bacteria or viruses get trapped behind the eardrum, usually after a cold or upper respiratory infection. The two bacteria most frequently responsible are Streptococcus pneumoniae and Haemophilus influenzae. Along with ear pain, you may notice fever, trouble sleeping, and irritability. Young children who can’t describe the pain often tug or rub at the affected ear.
Many middle ear infections clear up on their own within two to three days. For mild cases, a doctor may recommend watching and waiting to give the immune system a chance to handle it. If symptoms persist beyond that window or are severe from the start, antibiotics are typically needed. Pain relievers like acetaminophen or ibuprofen can help manage discomfort while the infection resolves.
Swimmer’s Ear (Outer Ear Infection)
When the pain is in the ear canal itself, rather than deep behind the eardrum, the likely culprit is an outer ear infection. Water that pools in the ear canal after swimming, bathing, or even humid weather creates a warm, moist environment where bacteria and fungi multiply quickly. You can often distinguish swimmer’s ear from a middle ear infection by gently tugging on your earlobe: if that motion increases the pain, the infection is probably in the outer canal.
Other signs include a feeling of fullness in the ear, itchiness, redness and swelling around the outer ear, muffled hearing, and sometimes fluid draining from the canal. Swollen lymph nodes near the ear or upper neck can also appear. Treatment usually involves prescription ear drops, and keeping the ear dry during recovery is essential.
Earwax Blockage
Earwax normally works its way out of the canal on its own, but sometimes it builds up and hardens into a plug. When that happens, it can press against the sensitive skin of the ear canal or against the eardrum, causing an ache, a feeling of fullness, ringing (tinnitus), and even temporary hearing loss. Some people also notice dizziness or itchiness. Using cotton swabs often makes the problem worse by pushing wax deeper. Over-the-counter drops designed to soften wax, or a gentle irrigation by a healthcare provider, usually resolves it.
Pressure Changes and Eustachian Tube Problems
Your eustachian tubes are narrow passages that connect your middle ears to the back of your throat. Their job is to equalize air pressure on both sides of the eardrum and drain fluid. When they don’t open and close properly, pressure builds up, fluid can accumulate, and the result is pain or a plugged sensation.
This dysfunction shows up in two main ways. The obstructive type means the tubes stay partially closed, trapping fluid and causing persistent ear pressure or pain. The baro-challenge type only causes symptoms during altitude changes, like flying, scuba diving, or driving through mountains. That sharp, sometimes intense ear pain during airplane descent is a classic example. In rare cases, untreated eustachian tube dysfunction can lead to hearing loss and permanent damage to the eardrum.
For airplane-related ear pain, a few techniques help. Stay awake during takeoff and landing so you can actively manage the pressure. Yawning and swallowing open the eustachian tubes, and chewing gum or sucking on candy makes swallowing easier. The Valsalva maneuver (gently blowing with your mouth closed and nostrils pinched) can also equalize pressure during ascent and descent. For chronic eustachian tube problems, treatments range from nasal sprays to minor procedures like placing small ear tubes that ventilate the middle ear for up to a year before falling out on their own.
Jaw Problems and TMJ Disorders
Not all ear pain comes from the ear. The temporomandibular joint sits on each side of your head directly in front of the ears, and when it’s inflamed or misaligned, the pain often feels like it’s coming from inside the ear itself. TMJ disorders produce an aching pain in and around the ear that tends to worsen with chewing, jaw clenching, or teeth grinding. You might also hear clicking or popping sounds when you open your mouth, or notice that your jaw feels stiff or locked.
If your ear pain gets worse when you eat, talk, or clench your jaw, and you don’t have signs of infection like fever or drainage, a jaw issue is worth investigating. Stress reduction, soft foods, gentle jaw stretches, and a night guard for teeth grinding are the usual starting points.
Dental Infections
A tooth abscess, particularly in the upper back teeth, can send pain radiating into the jawbone, neck, and ear. The pain is often severe, constant, and throbbing. Because the nerves serving the teeth and the ear run close together, it’s easy to mistake a dental problem for an ear problem. If you have ear pain alongside a toothache, swollen gums, or sensitivity to hot and cold foods, a dental evaluation may find the real source.
Nerve-Related Ear Pain
A less common but distinctive cause is glossopharyngeal neuralgia, a condition affecting a nerve that runs through the throat and ear area. The pain is sharp, stabbing, or shock-like and typically lasts just a few seconds to two minutes per episode. Episodes can strike several times a day and may even wake you from sleep. This pattern can persist for weeks or months, then disappear before returning later.
What sets nerve pain apart is its triggers. Everyday actions like swallowing, coughing, yawning, laughing, talking, or drinking cold beverages can set off a burst of intense pain around and underneath the jaw and ears. If your ear pain follows this pattern of brief, electric jolts tied to specific movements, it points toward a nerve condition rather than an infection or structural issue.
Ruptured Eardrum
A perforated eardrum can result from a severe infection, sudden pressure changes, a loud blast of sound, or even inserting an object too far into the ear canal. The moment it tears, you’ll typically feel a sharp pain followed by drainage, hearing loss, and sometimes ringing. Most ruptured eardrums heal on their own within a few weeks, though some take months. During healing, keeping water out of the ear is critical to prevent infection.
When Ear Pain Signals Something Serious
Mastoiditis is an infection of the bone directly behind the ear, and it’s one of the more dangerous complications of an untreated middle ear infection. The warning signs are pain, tenderness, and swelling behind the ear, sometimes enough to push the ear forward so it visibly sticks out. Redness behind the ear, high fever, headache, hearing loss, and discharge accompany the swelling. Without prompt treatment, mastoiditis can lead to permanent hearing loss or meningitis. If you notice swelling or redness behind the ear alongside fever and worsening pain, that combination needs urgent medical attention.
Other red flags worth acting on quickly include ear pain with sudden significant hearing loss, blood or pus draining from the ear, pain that steadily worsens over several days despite home care, or ear pain following a head injury.
