How do doctors diagnose an ear infection?

Not all children with ear infections need to see a doctor.

If your child can talk and tell you their ear is hurting, a painkiller such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) might be all your child needs. This should help with the pain and make your child more comfortable. And it's the treatment that your pediatrician or family doctor might suggest if they think your child has an ear
 
 
 
 
 
infection
You get an infection when viruses, bacteria, fungi or other tiny organisms get into your body. These bugs are so tiny that you can't see them without a microscope. For example, an infection in your airways causes the common cold. And an infection in your skin can cause rashes such as athlete's foot.
 
 
 
 
 
infection.

But if you're unsure what's wrong with your child, or painkillers don't seem to be working, then you should take them to see your doctor.

If your child can talk, the doctor will ask your child where it hurts and how they feel. The doctor may also ask you how long your child has had an earache and whether they have had it before. If your child can't describe their symptoms, or feels shy about talking in front of the doctor, your doctor will ask you about your child's symptoms and how long they have had the symptoms. Your doctor will probably also look inside your child's ear.

    otoscope to look at your child's ear canal and eardrum. This lets them see any redness or fluid behind the eardrum.
  • They might also gently push some air into your child's ear with this instrument to see if the eardrum moves.
  • If your child's eardrum is red, full of pus or fluid, or doesn't move, your child probably has an ear infection.

After talking with you and your child, and looking inside your child's ear, the doctor will probably be able to say whether your child has an ear infection.

However, if your child has problems hearing after the infection has cleared, they could have a condition called ear infection with fluid and might need some more tests. Doctors call this condition otitis media with effusion. To learn more, see our articles on Ear infection with fluid.
