Even malnourished children also have this problem. Some children have adenoids and tonsils problem. Because of that, they suffer from nose obstruction. There is a tube between the nose and the ear. If an infection occurs in the tube, there are more chances of infections in the middle ear.
Ear infection starts with ear pain, dullness and heaviness in the ear.
As it progresses and it becomes difficult to hear properly. There will be fever. As the pain increases and the eardrums burst, pus comes out into the ear. The pus is mopped out and antibiotics are used. With that treatment, the production of pus will decline.
