Every summer, the same scene repeats itself: hours spent in the water to cool off, then a dull pain that settles in the ear. Behind this inconvenience is often hidden otitis externa, an infection particularly common among swimming pool and sea swimmers. Children and adults alike can be affected during the summer period. Favored by humidity and long swimming sessions, this condition remains preventable thanks to a few simple actions recommended by specialists.
What are the symptoms of swimmer’s ear?
Also called otitis externa, this infection affects the skin of the ear canal. In a previous article, Dr. Amine Haricane explains that “the patient presents with mild pain in the ear, called otalgia, as well as discomfort, a feeling of having something inside.“
The specialist also recalls that “fever is an absent symptom. However, a discharge of pus, caused by an earwax blockage, is possible.“
The inflammation may be accompanied by itching, increased sensitivity when touching the ear, and in some cases discharge. The longer treatment is delayed, the more the pain is likely to intensify.
Why is this infection more common in summer?
High temperatures and repeated swimming create a favorable environment for the development of bacteria. When water becomes trapped in the ear canal, it maintains a warm, humid environment conducive to infections.
“In summer, two factors combine: ambient heat and prolonged exposure to water, particularly in a swimming pool or at sea. Persistent humidity in the ear canal promotes bacterial infections“, confirms Dr. Haricane.
Certain habits also increase risks. Excessive use of cotton swabs can push earwax toward the back of the ear and cause a blockage. Swimming in stagnant or insufficiently clean water also exposes you to more germs.
Actions to take to avoid otitis externa
Preventing this infection requires, above all, good ear hygiene. After each swim, it is advisable to tilt your head to each side to let the water drain naturally, then gently dry the outside of the ear.
“It is possible to use a salt water spray morning and evening, available in pharmacies, then remove the excess using a cotton swab without penetrating the ear canal.“, specifies the specialist.
For people prone to recurrence, suitable earplugs or a swimming cap can provide additional protection. Specialists also point out that earwax plays a natural role against bacteria and that it should not be systematically removed.
What to do if this persists?
In the event of persistent pain, a consultation remains essential. “Treatment depends on the origin of the infection: bacterial or mycotic. Ear drops based on antibiotics or antifungals are then prescribed, depending on the case.“, explains Dr. Haricane.
The examination also makes it possible to check the condition of the eardrum, to remove any earwax blockage and to ensure that no foreign body is present in the ear.
