What Causes Your Ear To Bleed?

Seeing blood from your ear is alarming, but it is not always a sign of something dangerous. Most causes are minor and treatable, like a scratched ear canal or a burst eardrum from an infection or pressure change. However, it can also signal a head injury or a serious infection, so knowing the exact cause matters. This article explains the common and less common reasons your ear might bleed, based on what medical evidence actually shows.

What Does It Mean When Your Ear Bleeds?

Blood from the ear, called otorrhagia, comes from somewhere in the ear canal, eardrum, or deeper structures. The most common cause is a scratch inside the ear canal from a fingernail, cotton swab, or other object. The skin in your ear canal is thin and has many blood vessels. Even a small scrape can produce a surprising amount of blood.

Research shows that about 90 percent of ear bleeding cases in otherwise healthy people come from minor trauma to the ear canal. This includes cleaning ears too aggressively. The American Academy of Otolaryngology warns against inserting anything smaller than your elbow into your ear for this reason.

A burst eardrum is another frequent cause. The eardrum is a thin membrane that separates the ear canal from the middle ear. When it tears, blood and sometimes clear fluid can leak out. This can happen from a loud blast, a sudden pressure change like in an airplane, or an ear infection that builds up enough pressure to rupture the drum.

Less common causes include foreign objects stuck in the ear, which is common in children, and head injuries. In rare cases, ear bleeding can come from a tumor in the ear canal or middle ear. But these are unusual. Most people with ear bleeding have a simple explanation that heals on its own.

What Causes Your Ear To Bleed From an Infection?

Ear infections are a common cause of ear bleeding, especially in children. A middle ear infection, called otitis media, can build up pus and fluid behind the eardrum. The pressure from this buildup can become strong enough to tear the eardrum. When the eardrum bursts, blood and pus drain out through the ear canal.

This sounds scary, but it often relieves the pain quickly. The eardrum usually heals on its own within a few weeks. According to the CDC, most eardrum ruptures from infection close without treatment. Antibiotics are sometimes needed if the infection itself does not clear.

Another type of infection that causes ear bleeding is swimmer’s ear, or otitis externa. This is an infection of the ear canal skin, not the middle ear. It happens when water stays in the ear after swimming or bathing, creating a moist environment where bacteria grow. The skin becomes inflamed, itchy, and painful. If it gets bad enough, the skin can crack and bleed.

Swimmer’s ear bleeding is usually minor. You might see streaks of blood on a tissue when cleaning the outer ear. The main treatment is antibiotic ear drops. The CDC recommends keeping the ear dry during treatment. Unlike middle ear infections, swimmer’s ear does not burst the eardrum. The bleeding comes from the canal skin itself.

Fungal infections of the ear can also cause bleeding, though this is less common in the United States. People with diabetes or weakened immune systems are more at risk. The fungus grows in the ear canal and can cause a dark, bloody discharge. This requires antifungal medication, not antibiotics.

Can a Head Injury Cause Your Ear To Bleed?

Yes, a head injury can cause ear bleeding, and this is the one situation where you need emergency medical attention. Bleeding from the ear after a blow to the head can mean a skull fracture or brain injury. The blood comes from inside the skull and leaks through a crack in the bone into the ear canal.

The most serious type is a basilar skull fracture. This is a break at the base of the skull. According to research published in the Journal of Trauma, about 24 percent of basilar skull fractures involve ear bleeding. This blood may be mixed with a clear fluid called cerebrospinal fluid, which surrounds the brain. If you see a ring of clear fluid around a blood stain on a pillow or tissue, that is a sign of a skull fracture.

Other symptoms of basilar skull fracture include bruising behind the ears, called Battle’s sign, and bruising around the eyes, called raccoon eyes. These do not always appear right away. They can take hours to develop.

If you or someone else has ear bleeding after any head injury, especially if they lost consciousness, are confused, or have a severe headache, call 911. Do not try to stop the bleeding by putting anything in the ear. Do not tilt the head to drain the blood. Just keep the person still and wait for help.

Minor head injuries, like a light bump that does not cause confusion, rarely cause ear bleeding. If bleeding happens with a minor bump, it is more likely from a scratch inside the ear canal that happened at the same time. But it is always safer to get checked.

What Causes Ear Bleeding From Pressure Changes?

Rapid changes in air pressure can cause ear bleeding. This is called barotrauma. It happens most often during airplane takeoffs and landings, scuba diving, or driving through mountains. The eustachian tube, which connects the middle ear to the back of the throat, normally equalizes pressure. When it cannot keep up, the pressure difference can stretch or tear the eardrum.

Scuba diving is a well-known cause. As you descend, water pressure increases. If you cannot equalize the pressure in your middle ear, the eardrum can rupture inward. This is painful and causes bleeding. Divers often describe a sudden sharp pain followed by a feeling of water rushing into the ear. The blood comes from the torn eardrum.

Flying causes the same problem but less severely. Most people feel ear pain during landing, not bleeding. Bleeding from flying is rare and usually happens in people who already have a cold, sinus infection, or blocked eustachian tube. The blocked tube cannot equalize pressure, and the eardrum tears.

Research from the Aerospace Medical Association shows that ear barotrauma is one of the most common medical problems in air travel. But bleeding is the least common symptom. Most people just feel pain and muffled hearing. If bleeding does occur, it usually stops quickly on its own.

To prevent barotrauma, chew gum or swallow during takeoff and landing. For scuba diving, descend slowly and equalize your ears frequently. Never dive with a cold or sinus infection. The risk of ear damage is much higher when your eustachian tubes are blocked.

What Are the Less Common Causes of Ear Bleeding?

Some causes of ear bleeding are rare but worth knowing about. One is a cholesteatoma. This is a skin cyst that grows in the middle ear behind the eardrum. It is not cancer, but it can destroy bone and damage hearing if left untreated. Cholesteatomas often develop after repeated ear infections. They cause a foul-smelling discharge that may be bloody. Surgery is the only treatment.

Tumors of the ear canal or middle ear are another rare cause. These are usually benign, meaning they are not cancer. But they can bleed when touched or as they grow. Glomus tumors are one example. They grow from blood vessels near the middle ear and can cause a throbbing sound in the ear along with bleeding. These tumors are treatable with surgery or radiation.

Blood clotting disorders can also cause ear bleeding. People on blood thinners like warfarin or apixaban may bleed more easily from minor ear injuries. A small scratch that would stop bleeding in a healthy person can continue to ooze. If you take blood thinners and your ear bleeds, even from a minor cause, tell your doctor. You may need to adjust your medication.

In very rare cases, ear bleeding can come from the inner ear itself. This is called a perilymph fistula. It is a leak of inner ear fluid into the middle ear. It can happen after a head injury, a sudden loud noise, or even from vigorous coughing or sneezing. Symptoms include hearing loss, vertigo, and a feeling of fullness in the ear. The discharge is usually clear fluid, but it can be tinged with blood.

When Should You See a Doctor for Ear Bleeding?

Most ear bleeding stops on its own and does not need emergency treatment. But there are clear signs that you need medical attention. See a doctor if the bleeding lasts more than 30 minutes. If it is heavy and does not slow down, go to the emergency room.

Any ear bleeding after a head injury, even a minor one, should be checked. The doctor needs to rule out a skull fracture. Also see a doctor if the bleeding is accompanied by severe pain, hearing loss, dizziness, or ringing in the ear. These symptoms suggest a more serious problem like a ruptured eardrum or infection.

Fever with ear bleeding means infection. This is especially important in children. A child with ear pain, fever, and bloody discharge likely has a middle ear infection that burst the eardrum. They need antibiotics if the infection does not clear on its own.

If you have diabetes or a weakened immune system, any ear bleeding should be evaluated. Infections that cause bleeding are harder to treat in these populations. Fungal infections, in particular, can spread quickly and cause serious damage.

The table below summarizes when ear bleeding is likely a minor issue versus when it needs urgent care.

What Should You Avoid Doing When Your Ear Bleeds?

There are several things people commonly do that make ear bleeding worse. The most important is to stop putting anything in your ear. Do not use cotton swabs, tissues, or your fingers to clean out the blood. You can push debris deeper or scratch the canal further. This delays healing and can introduce bacteria.

Do not use ear drops unless a doctor tells you to. Some drops are safe for the outer ear but toxic to the middle ear if the eardrum is torn. If you have a perforated eardrum, putting drops in can damage your hearing. Wait for a doctor to examine your ear first.

Do not try to stop the bleeding by packing the ear with cotton or gauze. This can trap blood and bacteria inside the ear canal, increasing infection risk. It also prevents the blood from draining naturally. Just let the blood flow out on its own and wipe the outer ear gently with a clean tissue.

Do not fly or scuba dive until the bleeding stops and a doctor clears you. Pressure changes can make a small eardrum tear much worse. If you have a perforated eardrum, the pressure difference during a flight can cause more damage and more bleeding.

Do not ignore the bleeding if it happens repeatedly. A single episode that stops quickly is usually nothing to worry about. But if your ear bleeds more than once without a clear cause, something else is going on. You need an ear exam to find the source.
