The middle ear is the small part of your ear behind your eardrum. It can get infected when germs from the nose and throat are trapped there.
A small tube connects your ear to your throat. A cold can cause this tube to swell. When the tube swells enough to become blocked, it can trap fluid inside your ear. This makes it a perfect place for germs to grow and cause an infection. Ear infections happen mostly to young children because their tubes are smaller and get blocked more easily.
The main symptom is an earache. It can be mild, or it can hurt a lot. Babies and young children may be fussy. They may pull at their ears and cry. They may have trouble sleeping. They may also have a fever.
You may see thick, yellow fluid coming from their ears. This happens when the infection has caused the eardrum to burst and the fluid flows out. This is not serious and usually makes the pain go away. The eardrum usually heals on its own.
When fluid builds up but does not get infected, children often say that their ears just feel plugged. They may have trouble hearing, but their hearing usually returns to normal after the fluid is gone. It may take weeks for the fluid to drain away.
To help prevent ear infections:
Most ear infections go away on their own. You can treat your child at home with an over-the-counter pain reliever like acetaminophen (such as Tylenol), a warm face cloth or heating pad on the ear, and rest. Do not give ASA to anyone younger than 20. Your doctor may give you eardrops that can help your child's pain.
Your doctor can give your child antibiotics, but ear infections often get better without them. Whether you use them will depend on how old your child is and how bad the infection is.
Sometimes after an infection, a child cannot hear well for a while. Call your doctor if this lasts for 3 to 4 months.
Minor surgery to put tubes in the ears may help if your child has hearing problems or repeat infections.
