Because allergies can lead to many different ear-related conditions, they also trigger a number of signs and symptoms, including:

• Ear pressure and pain
• Decreased hearing or hearing loss (temporary)
• Ringing in the ears (tinnitus)
• Dizziness (vertigo)
• Sense of fullness and “popping” in the ears
• Ear itchiness
• Drainage from the ear
• Congested and/or runny nose
• Nausea, vomiting
• Fever
• Snoring

Children may be irritable, inconsolable and/or pull at their ears. Increased crying, difficulty sleeping, loss of appetite and increased breathing through the mouth may also occur. 

Prolonged ear-related problems can affect hearing, which may result in delayed speech development and other developmental disorders.

Although it is a rare occurrence, ear infections can lead to permanent hearing loss. The risk for this complication increases with each ear infection.

In order to prevent hearing loss and other complications, patients displaying the signs and symptoms of an ear infection should see a physician.
