Adult ear infections are usually one of two types: otitis media or middle ear infection and otitis externa also known as swimmer’s ear. Both are common ear infections in adults.

Ear Infections
The most common cause of problems in the middle ear comes from bacteria or viral infections. Bacteria travel to the middle ear by way of the Eustachian tube, where it resides in the lining and ultimately develops into an infection. The infection causes the lining of the middle ear to swell; this comes to block the tube.

During the infection, pus may accumulate in the middle ear due to accumulation of dead bacteria and the white cells dispersed by the body to fight the infection. The accumulated pus buildup hinders the movement of the middle ear bones and eardrum resulting in impaired hearing and severe pain.

Symptoms
Symptoms of an ear infection for both otitis media and otitis externa include the following signs:

• Ear pain
• Blockage of the ear canal
• Temporary hearing loss
• Fever
• Dizziness
• Upset stomach
• Vomiting
• Diarrhea
• Inflammation in the ear
• Pain when moving the ear lobe
• Discharge from the ear
• Itchiness inside the ear
• Unpleasant odor emanating from the ear

Treatment
In some cases, an ear infection may clear up on its own. Bacterial infections that do not clear up on their own are treated with eardrops and oral antibiotics such as amoxicillin. If the ear is swollen, inflamed and causing pain, anti-inflammatory drugs along with an over-the-counter or prescribed painkiller may be taken for relief.

Viral Infections are more difficult to treat and may require minor surgery know as myringotomy. This procedure requires placing small tubes in the infected eardrum that allows draining of fluid buildup and provides a vent to relieve pressure buildup. The tubes are not permanent.

Consult a health care provider when experiencing symptoms and signs of ear infections as they can also signify other health problems.
