An earache is pain in one or both ears. It can feel sharp, dull, or burning. The pain may be constant or come and go. Most earaches are caused by a problem in the middle ear, the outer ear canal, or the area around the ear. In adults, the cause is often an infection, but it can also be pressure changes, injury, or referred pain from the jaw or teeth.
What Are The Causes Of An Earache? Explained
The most common cause of an earache is a middle ear infection, known medically as otitis media. This happens when fluid builds up behind the eardrum and becomes infected. Bacteria or viruses travel up the Eustachian tube, the small passage that connects the middle ear to the back of the throat. When this tube swells and blocks, fluid cannot drain.
Outer ear infections are another frequent cause. This condition, called otitis externa or swimmer’s ear, affects the ear canal. It happens when water stays in the ear after swimming or bathing, creating a moist environment where bacteria grow. Scratching the ear with fingers or cotton swabs can also damage the skin and lead to infection.
Some earaches have nothing to do with the ear itself. The ear shares nerves with the jaw, teeth, and throat. A dental abscess, a sore throat, or temporomandibular joint (TMJ) disorder can send pain signals that feel like they come from the ear. Doctors call this referred pain.
What Does a Middle Ear Infection Feel Like?
A middle ear infection often follows a cold or flu. The Eustachian tube swells because of the respiratory infection. Fluid builds up behind the eardrum. Pressure increases, and the eardrum stretches. That stretching is what causes the pain.
Most people describe the pain as deep and throbbing. It may worsen when lying down because fluid shifts and pressure changes. Fever is common, especially in children. Hearing may seem muffled because the fluid blocks sound transmission. Some people feel fullness or popping in the ear.
In severe cases, the pressure can rupture the eardrum. This usually releases the pressure and relieves pain quickly. A small amount of blood or pus may drain from the ear. The eardrum typically heals on its own within weeks, but anyone who experiences ear drainage should see a doctor.
Why Does My Ear Canal Hurt?
Pain in the outer ear canal feels different from middle ear pain. It is often sharper and worse when you touch the ear or pull on the earlobe. The canal may look red and swollen. Itching often precedes the pain by a day or two.
Swimmer’s ear is the most common cause. The medical term is acute otitis externa. It is more common in summer months and in people who swim frequently. But you do not need to swim to get it. Humidity, sweating, or using earbuds for long periods can trap moisture in the canal.
Inserting objects into the ear is a major risk factor. Cotton swabs push wax deeper and scratch the delicate skin. Hearing aids, earplugs, and earbuds can irritate the canal. Skin conditions like eczema or psoriasis can also affect the ear canal and cause itching and pain.
Fungal infections are less common but possible. They tend to occur after long courses of antibiotic ear drops or in people with weakened immune systems. Fungal infections often cause intense itching along with pain.
Can Jaw or Teeth Problems Cause Ear Pain?
Yes. This is one of the most overlooked causes of earache. The trigeminal nerve and the facial nerve supply sensation to both the ear and the jaw structures. When pain originates in one area, the brain can interpret it as coming from the other.
TMJ disorder is a common source of referred ear pain. The temporomandibular joint sits just in front of the ear. When this joint is inflamed or misaligned, pain radiates into the ear region. People with TMJ problems often notice their ear pain worsens when chewing, yawning, or clenching their jaw.
Dental problems can also cause ear pain. An abscessed tooth, especially in the back molars, can produce pain that feels like it is inside the ear. Impacted wisdom teeth are another possible cause. If your ear hurts but the ear itself looks normal and no infection is present, a dentist should evaluate your teeth and jaw.
Some research suggests that nighttime teeth grinding is a frequent hidden cause of chronic ear pain. People wake with ear discomfort that they assume is an infection, but the real problem is jaw muscle strain from clenching all night.
What Other Conditions Cause Earaches?
Several less common conditions can produce ear pain. Knowing them helps you recognize when to seek medical care.
Eustachian tube dysfunction causes a feeling of fullness and pressure without infection. The tube fails to open properly, often after a cold, during allergy season, or with rapid altitude changes. Air pressure inside the middle ear cannot equalize with the outside environment. This produces discomfort rather than sharp pain.
Foreign objects in the ear are more common in children but can affect anyone. Small toys, beads, or insects can become lodged in the canal. This causes pain, muffled hearing, and sometimes discharge. Never attempt to remove a foreign object with tweezers or cotton swabs. See a doctor.
Earwax buildup can cause pain when it hardens and presses against the eardrum. It more commonly causes fullness and hearing loss than sharp pain. Attempting to remove wax with cotton swabs often pushes it deeper and makes the problem worse.
Mastoiditis is a serious bacterial infection of the mastoid bone behind the ear. It is a complication of untreated middle ear infection. Symptoms include severe pain, swelling behind the ear, redness, and fever. This condition requires immediate medical attention.
Shingles can affect the ear if the varicella-zoster virus reactivates along the facial nerve. Pain may precede the characteristic rash by several days. This condition, called Ramsay Hunt syndrome, can cause facial weakness and hearing problems. Anyone with ear pain and a rash should see a doctor urgently.
When Should I See a Doctor for an Earache?
Most earaches resolve on their own within a few days. But some situations require medical evaluation. See a doctor if you have severe pain, fever above 102°F, or symptoms lasting more than two days.
Seek urgent care if you experience any of these signs:
- Drainage of pus or blood from the ear
- Sudden hearing loss
- Severe dizziness or vertigo
- Swelling or redness behind the ear
- Facial weakness or numbness
- Stiff neck or confusion
Children need medical attention sooner than adults. An infant with an earache may pull at the ear, cry more than usual, have trouble sleeping, or show poor feeding. Babies under six months with suspected ear infection should see a doctor promptly.
People with weakened immune systems, diabetes, or a history of ear surgery should also seek care early. What looks like a simple infection can become more serious in these populations.
How Are Earaches Treated?
Treatment depends entirely on the cause. Many ear infections resolve without antibiotics. The body’s immune system clears viral infections on its own. Even some bacterial infections resolve without medication.
Pain relief is the first line of treatment for most earaches. Over-the-counter acetaminophen or ibuprofen reduces pain and fever. Warm compresses applied to the outside of the ear can provide comfort. Keeping the head elevated helps fluid drain from the middle ear.
Antibiotics are prescribed only when a bacterial infection is confirmed or strongly suspected. Overusing antibiotics for viral infections contributes to antibiotic resistance. Your doctor may recommend a watch-and-wait approach for mild infections, especially in older children and adults.
For outer ear infections, prescription ear drops are the standard treatment. These drops usually contain antibiotics and sometimes steroids to reduce swelling. You should keep the ear dry while using the drops. Avoid swimming until the infection clears.
If the earache is caused by TMJ disorder or dental problems, treating the underlying condition resolves the ear pain. This may involve dental work, a mouthguard for grinding, or physical therapy for the jaw.
Frequently Asked Questions
Can stress cause ear pain?
Stress itself does not directly cause ear pain, but it can lead to jaw clenching and teeth grinding, which can produce referred ear pain. Stress also lowers pain tolerance and may make existing discomfort feel worse.
Why does my ear hurt when I swallow?
Swallowing activates muscles and nerves near the Eustachian tube, which can aggravate an inflamed middle ear or throat infection. This symptom often points to a middle ear infection or tonsillitis, not an outer ear problem.
How long does an earache last without treatment?
Most viral ear infections clear within two to three days without treatment. Bacterial infections may last longer and sometimes require antibiotics to resolve completely.
Is it safe to fly with an earache?
Flying with an earache can be painful because cabin pressure changes affect the middle ear. If you must fly, chew gum, swallow frequently, or use a decongestant before takeoff and landing to help equalize pressure.
