Outer Ear Infection
Outer Ear Infection

Otitis externa, a medical word for an infection in the ear canal that links your outer
and middle ears, is another name for an outer ear infection. The canal is also responsible for transporting sound waves from the environment to the eardrum. The most frequent cause of ear pain is an outer ear infection, which affects one out of every ten adults at some point in their lives.
Outer ear infections can also be caused by fungi, such as yeast, or viruses, in addition
to bacteria. Outer-ear infections are usually referred to as &quote; swimmer's ears & quote; because of the ease with which germs can enter the ear canal when swimming. Allergic responses can cause outer ear infections. This type of infection usually clears itself within a few days or weeks. However, in some cases, the sickness may spread to other tissues.


Causes of Outer Ear Infection

An outer ear infection might result from excessive swimming, bathing, or showering.
Bacteria can thrive in the fluids left in the ear canal.
The skin covering the ear canal can potentially become infected if damaged. Using
headphones, scratching your ear, or putting cotton swabs in your ear can harm this
delicate skin.
When this layer of skin is injured and inflamed, it can serve as a platform for
bacteria to thrive. Exposure to wetness and scratching can cause a depletion of the
ear's cerumen, leading to an increased risk of infection.


Ear pain, inflammation, and tenderness in the outer ear are symptoms. Symptoms
may not appear for up to 48 hours.

Risk Factors of Outer Ear Infection

Swimming, ear canal damage, and other reasons can lead to outer ear infections.

outer ear infections.

cotton swabs or wear headphones in your ear.
 People who have previously had an outer ear infection or are prone to
infections are more likely to develop a new infection in the outer ear.

can cause an outer ear infection.
