Swimmer’s Ear(Otitis Externa): Causes, Symptom & Treatment

Do you complain of having pain and irritation inside your ear? Did you notice any redness or discomfort after frequently using cotton swabs to clean your ear? These may be the signs of a swimmer’s ear, one of the most common bacterial infections of the ear. Visit an ENT specialist if you have any such problems and get yourself treated before the infection spreads to deeper parts of the ear. 

Overview of Swimmer’s Ear

Swimmer’s ear is a bacterial infection caused due to remnant water inside the ear. This moist environment becomes favourable for bacterial growth that causes infections inside the ear. If left untreated, a swimmer’s ear can worsen and spread deeper inside the ear. 

About Swimmer’s Ear

Swimmer’s ear / Otitis Externa is a bacterial infection affecting the external ear and extends from the ear canal up to the eardrum. It occurs due to water accumulated inside the ear after swimming or bathing, creating a moist environment favourable for bacterial growth. It is one of the most common bacterial infections affecting the ear canal. Apart from the damp environment inside the ear, frequent use of cotton swabs, pushing fingers inside the ear, and other objects may also cause a swimmer’s ear. It may lead to the damage of the thin lining of the ear canal. If left untreated, a swimmer’s ear can worsen and spread deeper inside the ear. Therefore prompt treatment is advisable to prevent further complications. 

Causes and Symptoms of Swimmer’s Ear

Some of the most common causes of swimmer’s ear are

  • Putting objects inside the ear like cotton swabs, ear pins, pen caps, fingers, etc., to clean the ears causes scratches or abrasions inside the ear canal. 
  • Trapped moisture inside the ear while swimming, showering or bathing causes bacterial infection. 
  • Sweat can also cause a swimmer’s ear. 
  • People with narrow ear canal.
  • Age factor- can be seen in all age groups but is most common in children. 
  • Skin problems like eczema and psoriasis can cause a swimmer’s ear, and so can cosmetic products or jewellery causing sensitivity reactions.

People suffering from swimmer’s ear often complain of the following symptoms-

  • Itching inside the ear
  • Irritation and discomfort
  • Pain, when left untreated, can become severe.
  • Difficulty in hearing .

Perception of sound may seem as muffled due to swelling of the ear canal.

  • Oozing pus or fluid from the ear canal 
  • A feeling of fullness inside the ear may lead to partially blocking the ear canal.
  • In severe conditions, pain radiates towards the face, neck, and on the sides of the head and may even cause complete blockage of the ear canal, swelling of the lymph nodes of the neck.  

When to see a doctor
