An audiologist has warned swimmers of the dangers of contracting 'swimmer's ear' (otitis externa).

Keith Ross says that swimmer's ear is a common summertime condition but if left untreated it can result in complications such as hearing loss.

Otitis externa is referred to as 'swimmer's ear' as repeated exposure to water increases the risk of contracting the condition.

When water gets trapped inside the ear it creates moisture, which encourages bacteria to grow and can cause infection. 

"It's important to remember to protect your ears during water activities. Swimmer's ear is a common complaint, especially in older children and adults who swim regularly or get unclean water in their ears, and people often get it after a day at the beach or pool," said Keith Ross, who works for Hidden Hearing.

While the condition is not serious if it is treated quickly, it can cause severe pain, and can lead to hearing complications if left untreated.

The most common symptoms of swimmer's ear are pain and discomfort inside the ear or a sensation of an itchy ear canal. Other possible signs include difficulty with hearing, a blocked feeling in the ear, discharge, or redness and swelling.

Swimmer's ear is usually treated successfully with eardrops and painkillers.
