Quick Scoop

Otomycosis is a fungal ear canal infection , and people usually get it when the ear stays warm, damp, or irritated —for example from swimming, heavy sweating, cotton swab use, hearing aids/earbuds, eczema, or recent antibiotic/steroid ear drops. It’s fairly common , especially in warm or humid climates, and one source estimates it makes up about 10% to 40% of otitis externa cases.

How people get it

  • Moisture in the ear. Fungi grow better in warm, damp environments, so swimming or water trapped in the ear can raise risk.
  • Ear canal irritation or trauma. Cotton swabs, scratching, hearing aids, or earbuds can damage the skin barrier and make infection more likely.
  • Underlying conditions. Diabetes, eczema, psoriasis, and weakened immunity are common risk factors.
  • Medication exposure. Some sources note that antibiotic or steroid ear drops can increase risk by changing the ear canal environment.

How common is it?

Otomycosis is described as relatively common and is reported to account for roughly 10% to 40% of outer-ear infections in some clinical sources. It is reported more often in warm, humid, tropical, or summer conditions , and often affects adults in the 20 to 40 age range.

What Reddit usually sounds like

I can’t verify live Reddit threads from here, but discussions people usually have about otomycosis tend to center on:

  • “Why won’t this itchy ear go away?”
  • “Did swimming or Q-tips cause this?”
  • “How long does treatment take?”
  • “Why does it keep coming back?”

That matches the medical risk factors above: moisture, scratching, and ear- canal irritation are the big repeat themes.

When to get checked

If you have ear pain, persistent itching, discharge, bad smell, reduced hearing, or symptoms that keep coming back , it’s worth seeing a clinician, because otomycosis is usually treated with ear cleaning plus antifungal drops or cream.
