Ear drainage, often described as a "running ear," is most commonly caused by an infection or a ruptured eardrum. The characteristics of the drainage can help determine the underlying cause.
Possible Causes of Ear Drainage
-
Ear Infection: This is the most frequent reason for ear drainage. The fluid may appear cloudy, whitish-yellow, or like pus. A foul smell can also accompany pus resulting from an infection. Both middle ear infections (otitis media) and outer ear infections (otitis externa, or swimmer's ear) can lead to drainage. Chronic ear infections (persistent or recurring infections) are particularly likely to cause pus-like drainage.
-
Ruptured Eardrum (Tympanic Membrane Perforation): An ear infection, trauma, or significant pressure changes (like during air travel or scuba diving) can rupture the eardrum. Drainage following a ruptured eardrum may be bloody, clear, or pus-like.
When to See a Doctor
It's important to consult a doctor if you experience ear drainage, especially if:
- The drainage is pus-like or foul-smelling.
- You experience ear pain.
- You have a fever.
- Your hearing is affected.
- The drainage follows a head injury.
A doctor can properly diagnose the cause of the drainage and recommend appropriate treatment, which may include antibiotics for infections or observation and pain management for a ruptured eardrum while it heals.
