Ear infections occur when fluid fills the space between the eardrum and the inner ear. This happens when the eustachian tube becomes blocked thanks to a virus or bacterium, preventing mucus and pus from draining out of the middle ear. These fluids put pressure on the eardrum, causing pain and discomfort.
Symptoms
The first sign of an ear infection may be an increase in irritability. Some children cry inconsolably. You may notice your child pulling or tugging on the ear. In addition to a painful earache that is worse when lying down, symptoms of ear infection include fluid discharge from the affected ear, a feeling of fullness in the ear, difficulty hearing, trouble sleeping, headache, fever, dizziness, vomiting, diarrhea, and a lack of appetite. An ear infection is easily diagnosed through an examination of your child’s ears with an otoscope. If the ears appear dull or red, contain fluid behind the eardrum or pus inside the middle ear, then an ear infection is likely to blame. A hearing test may be recommended, especially if your child has had ear infections in the past.
