Ear pain may be due to a disorder within the ear itself or a disorder in a nearby body part that shares the same nerves to the brain as the ear. Such body parts include the nose, sinuses, throat, and temporomandibular joint (TMJ).
With acute pain (pain for less than 2 weeks), the most common causes are
Middle and external ear infections cause painful inflammation. A middle ear infection also causes a build up of pressure behind the eardrum (tympanic membrane [TM]). This build up of pressure is painful and also causes the eardrum to bulge. After the eardrum bulges, it occasionally bursts and releases a small amount of pus and/or blood from the ear. Rarely, a middle ear infection spreads to the mastoid bone behind the ear (causing mastoiditis Mastoiditis Mastoiditis is a bacterial infection in the mastoid process, which is the prominent bone behind the ear.

Pressure changes during airplane flights and underwater diving can cause ear pain (see also Barotrauma of the Ear Barotrauma of the Ear Barotrauma is an injury caused by increased air pressure, such as during airplane flights or scuba diving. Barotrauma can cause ear pain or damage to the eardrum. The eardrum separates the ear... read more ). Such ear pain occurs when the tube that connects the middle ear and the back of the nose (eustachian tube) is blocked or fails to function normally. The blockage or dysfunction keeps pressure in the middle ear from equalizing with outside pressure. The pressure difference pushes or pulls on the eardrum, causing pain. Pressure changes can also cause the tympanic membrane to rupture.
With chronic pain (pain for more than 2 to 3 weeks), the most common causes are
A less common cause of chronic pain is pain from disorders affecting the larynx (voice box), including cancer (called referred pain).
The following information can help people with earache decide when a doctor's evaluation is needed and help them know what to expect during the evaluation.
In people with earache, certain symptoms and characteristics are cause for concern:
Diabetes, a compromised immune system, or chronic kidney disease
Redness and swelling behind the ear
Severe swelling at the opening of the ear canal
Fluid draining from the ear
Chronic pain, especially in people who have other head/neck symptoms (such as hoarseness, difficulty swallowing, or nasal obstruction)

Then, a delay of a week or so is usually not harmful. People with acute pain should see a doctor within a few days (or sooner if pain is severe).
Doctors first ask questions about the person's symptoms and medical history. Doctors then do a physical examination that is focused on the ears, nose, and throat. What they find during the history and physical examination often suggests a cause of the earache and the tests that may need to be done (see table Some Causes and Features of Earache Some Causes and Features of Earache Earache usually occurs in only one ear. Some people also have ear discharge or, rarely, hearing loss. Ear pain may be due to a disorder within the ear itself or a disorder in a nearby body part... read more ).
In addition to the presence of warning signs, an important feature is whether the ear examination is normal. Middle and external ear disorders cause abnormalities, which, when combined with the person's symptoms and other medical history, usually suggest a cause.
People with a normal ear examination may have ear pain for another reason, such as tonsillitis Tonsillopharyngitis Sore throat is pain in the back of the throat. The pain can be severe and is usually worsened by swallowing. Many people with sore throat refuse to eat or drink. Sometimes pain is also felt... read more . If no abnormalities are found during the ear examination but the person has chronic pain, doctors sometimes suspect the ear pain might be due to a TMJ disorder Temporomandibular Disorders read more . However, people with chronic pain should have a thorough head and neck examination (including fiberoptic examination) to rule out cancer or a tumor in the nasal passages and upper throat (nasopharynx).
Most often, the doctor's examination provides a diagnosis, and tests are not needed. However, people with a normal ear examination, particularly those with chronic or recurrent pain, may need tests to look for cancer. Such tests usually include examination of the nose, throat, and voice box (larynx) with a flexible viewing scope (endoscope) and magnetic resonance imaging (MRI) of the head and neck.
The best way to treat earache is to treat the underlying disorder.
People may take a pain-relieving drug by mouth. Usually a nonsteroidal anti-inflammatory drug (NSAID) or acetaminophen is adequate. However, some people, particularly those who have a severe external ear infection, may need to take an opioid such as oxycodone or hydrocodone for a few days. For a severe external ear infection, doctors also often suction pus or other discharge from the ear canal and insert a small foam wick. The wick can be soaked with antibiotic and/or corticosteroid ear drops.
Ear drops that contain pain relievers (such as antipyrine/benzocaine combinations) are generally not very effective but can be used for a few days. These drops (and any other ear drops, such as those to remove earwax) should not be used by people who might have a perforated eardrum, so a doctor should be consulted before drops are used.
People should avoid digging in their ears with any objects (no matter how soft the object or how careful people think they are). Also, people should not try to flush out their ears unless instructed by a doctor to do so, and then only gently. An oral irrigator (such as used for teeth cleaning) should never be used in the ear.
