Overview Putting fingers, cotton swabs or other objects in your ears also can lead to swimmer's ear by damaging the thin layer of skin lining your ear canal. Swimmer's ear is also known as otitis externa. The most common cause of this infection is bacteria invading the skin inside your ear canal. Usually you can treat swimmer's ear with eardrops. Prompt treatment can help prevent complications and more-serious infections.

Earache (Ear Pain) Otitis externa can also be caused by putting objects into the ear canal. Objects to clean the ear (for example, paper clips, bobby pins, or fingernails) should not be used as they may tear the skin.

The World's Longest-Burning Light Bulb Has Shone for 110 Years The World's Longest-Burning Light Bulb Has Shone for 110 Years. Adolphe A. Chaillet's carbon filament bulb long outlasted the man himself. Incandescent light bulbs may be fading away, killed off slowly by fluorescents and LEDs, but there's one old-fashioned bulb that refuses to go out. In fact, it's been going for more than a century. The world's longest-burning light bulb has been shining since 1901, when it was first turned on in Livermore, Calif.

Overview Conditions of the middle ear that may be related to an ear infection or result in similar middle ear problems include the following: Otitis media with effusion is inflammation and fluid buildup (effusion) in the middle ear without bacterial or viral infection. This may occur because the fluid buildup persists after an ear infection has resolved. It may also occur because of some dysfunction or noninfectious blockage of the eustachian tubes. Chronic otitis media with effusion occurs when fluid remains in the middle ear and continues to return without bacterial or viral infection. This makes children susceptible to new ear infections, and may affect hearing. Chronic suppurative otitis media is a persistent ear infection that often results in tearing or perforation of the eardrum.

Swimmer's ear: What you need to know There are three types of external otitis, including swimmer's ear. Acute diffuse otitis externa, or swimmer's ear.

A rash can extend to the outer ear and the ear drum.

Otitis Media with Effusion Normally, the Eustachian tube drains fluid from your ears to the back of your throat. If it clogs, otitis media with effusion (OME) can occur. If you have OME, the middle part of your ear fills with fluid. It can increase the risk of ear infection. OME is extremely common. According to the Agency of Healthcare Research and Quality, about 90 percent of children will have OME at least once by the age of 10.
