Article: In general, children are more likely to get ear infections than adults. This is because the eustachian tubes (tubes running from the middle of each ear to the back of your throat) are smaller in children and more prone to fill with fluid. Children also have weaker immune systems than adults and are also more prone to viral infections such as colds. Anything that blocks the eustachian tube can cause an ear infection. There are other risk factors for an ear infection, including: Allergies Respiratory infections such as colds and sinus infections Infection or trouble with the adenoids (lymph tissue in your upper throat area) Tobacco smoke Excess mucus or saliva, such as that produced during teething Living in a cold climate Changes in altitude or climate Not being breastfed as an infant Recent illness Attending daycare, especially a larger daycare with many children A middle ear infection (acute otitis media) is the most common type of ear infection and hence recognizing its symptoms is very important. Middle ear infection is caused by a virus or bacteria. The middle ear is the space just behind the eardrum that contains the small bones that pass vibrations to the inner ear. When the area becomes filled with fluid, bacteria and viruses can get in and cause an infection. An ear infection often occurs after a respiratory infection such as a cold, although severe allergies may also bring one on. Symptoms of a middle ear infection include: Ear pain or an earache Feeling of fullness in the ear Feeling ill Vomiting Diarrhea Hearing loss in the infected ear Tinnitus Dizziness Ear drainage Fever, especially in children " Swimmers' ear, also known as otitis externa or an "external ear infection," is an infection of the outer ear canal caused by bacteria or fungi. Moisture is a common culprit for this type of infection (hence the name), but scratching or inserting things into the ear canal can also leave you prone to infection. Symptoms may begin as mild but often worsen, and include: Itching in your ear canal Redness inside the ear Discomfort that worsens if you pull or push on your outer ear Ear drainage (begins clear and odorless, may progress to pus) More severe symptoms include: Feeling of fullness or blockage Decreased hearing Severe pain that radiates outward to your face or neck Swelling of neck lymph nodes Fever Young children may display different symptoms of ear infection than older children and adults. Because young children often cannot communicate how they're feeling, look for the following symptoms: Tugging, pulling or scratching the ear Banging the head around Fussiness, irritability, or incessant crying Difficulty sleeping Fever (especially for infants and very young children) Fluid drainage from the ear Clumsiness or balance problems Trouble hearing Most ear infections can be treated at home, and many go away on their own. However, if you or your child experience certain symptoms, you should contact your doctor immediately. These symptoms include: Blood or pus in ear drainage (may look white, yellow, green, or pinkish/red) Continued high fever, especially if it is over 102F (39C) Dizziness or vertigo Stiff neck Tinnitus Pain or swelling behind or around the ear Ear pain that lasts more than 48 hours
