Earaches are often caused by ear infection. FamilyDoctor.org explains that infection of the ear occurs when the tube that connects the middle ear to the back of the nose is unable to drain fluids properly from the ear. This inflammation and swelling can be the result of allergies, colds or any other infection. An earache can also be the result of something getting lodged in the ear, such as a small toy, earwax or even water. Identifying an earache in infants can be difficult, especially soon after it begins.
Vocalization
Dr. Alan Greene, a pediatrician, points out that infants cannot explain the pain they feel but they can communicate via crying, fussiness or irritability. This can increase when the child is lying down because the pressure worsens in this position. A sudden inability to sleep during naps or at night can indicate that your child is feeling more pain while lying down. It is possible for a child to feel perfectly fine when upright even after a night of trouble sleeping from an earache.
Shaking Head
In older babies, an earache may lead to a sensation of fullness or diminished hearing. This symptom can lead to an infant shaking her head frequently. A very young infant may not be able to exhibit this symptom.
Other Symptoms
An earache from an infection can lead to a low-grade fever, loose stools or vomiting. Signs of an earache that accompany other illnesses, such as respiratory infection or the common cold, may be due to an infection. Ear infections are often caused by fluid buildup from such illnesses. Ear redness or drainage from the ear can indicate infection.
