It is a bacterial or viral infection that affects the part of the ear just behind the eardrum. The infection causes inflammation and fluid-build up which can be very painful. Ear infections occur when one of the auditory tubes get blocked or swell up. This is could arise due to: 

• Allergies 

• Cold

Symptoms 

• Pain or discomfort inside the ear 

• The persistent pressure inside the ear 

• Pus-like liquid that drains from the ear 

• Loss of hearing  

These symptoms might be persistent or can come and go. It can affect one or both years and could be accompanied by fever. This infection can even affect infants.  

Diagnosis and treatment 

If the problem is persistent especially amongst infants it is best to consult a doctor. The doctor performs a simple diagnosis using focused light and a magnifying glass. If you have the infection: 

• Pus-like fluid and redness inside the ear 

• Bulging eardrum 

• Perforations 

• Fluid draining 

In advanced stages, a sample of the fluid is taken to find out what kind of bacteria has caused the infection.  

Mild infections clear off on their own. The doctor prescribes painkillers and eardrops to relieve pain and irritation. In certain cases, a course of antibiotics is prescribed while advanced stages might require surgery.
