Common Causes of Earache
Earache is commonly associated with a sore throat, cold and flu.
The eustachian tube is a common junction between the throat and middle ear and through this passage, air is transferred to the middle ear and assist to maintain the air balance.
Adenoids are soft tissue structure made up of immune cells. The positioning of this soft tissue barrier in between the nose and middle ear not only provide a padding system but also fight against the germs coming through the air from mouth. But in case of compromised immunity or under the developed immune system (in case of children), the infection occurs in the middle ear and earache develops.
Streptococcus pneumoniae and Haemophilus influenzae are two very common microorganisms detected, which causes an ear infection. 
The common types of ear infections are as follows:
Acute otitis media (AOM) is an ear infection affects the middle ear, in which fluid is accumulated behind the eardrum and inflammation takes place. It is the more common cause of an earache and affects mostly children. Fever is often associated with this infection
Otitis media with effusion (OME) occurs after an initial ear infection is over and symptoms may disappear; but some discomfort in the ear prolongs due to the accumulation of fluid behind the eardrum, which can be seen only through special ear examining instrument.
Chronic otitis media with effusion (COME) is a resultant of recurrence of ear infection or the accumulated fluid in the eardrum unable to clear out and linger in the middle ear for a prolonged period. It can cause hearing loss. 
The eustachian tube assists to excrete fluid trapped in the middle ear. When individual suffering from cold and flu, then the mucus is stuck in the Eustachian tube and block the tube. This leads to accumulation of fluid in the middle ear and causes ear pain.
As we discuss earlier, the children are more vulnerable to get an ear infection, especially Acute otitis media because of the following reasons:
- Child stay in daycare facilities.
- Bottle feeding.
- Habituated with soother.
Besides these, males and, Caucasians are more susceptible towards ear infection.
Certain disease conditions, like tonsil enlargement or enlargement of adenoids, medical history of AOM, family history of Acute otitis media, active or passive smoking, nasopharynx anatomical disorders, including Down syndrome and cleft palate etc. can also trigger ear infection related earache.
However, upper respiratory tract infection, insertion of a foreign substance in the ear canal can also cause an earache.
In case of administration of foreign object need medical assistance to clear out. But don't try by yourself, as it may harm the internal structure of the ear.
In some cases, fluid is accumulated during swimming and fluid lodging in the ear canal cause an earache and untreated condition may lead to ear infection and prolong an earache.
