Ear Infection vs. Blocked Ear: What is Causing the Pain?
Why "Earache" doesn't always mean you need antibiotics—and how to tell the difference between Infection, Fluid, and Wax.

With nearly 2,000 monthly searches for “Ear Infections” in Melbourne alone, ear pain is one of the most common reasons patients seek urgent care. However, pain (ear ache) is a symptom, not a diagnosis.
At LAC Audiology, we often see patients who believe they have an infection, only to find they are suffering from impacted earwax or fluid buildup. Before reaching for generic ear drops, it is crucial to understand what is happening inside your canal.
Identifying Your Ear Ache
Middle Ear (Otitis Media):
The Feeling: Deep, throbbing pressure behind the eardrum.
The Cause: Often occurs after a cold/flu. The Eustachian tube blocks, trapping fluid behind the drum.
Action: Requires GP management (antibiotics or steroids).
Outer Ear (Otitis Externa):
The Feeling: Sharp, stinging pain. The ear is tender to touch (especially the lobe).
The Cause: Bacteria or fungus in the ear canal (often from swimming or scratching).
Action: Microsuction is recommended to clear the infected debris so drops can work.
Wax Impaction:
The Feeling: Dull ache, fullness, or “plugged” sensation. No fever.
The Cause: Hard wax pressing against the sensitive canal skin.
Action: Microsuction can bring quick relief.
The Blockage
Drops enter the ear but splash against a wall of wax. They never reach the infection site or the eardrum.
Microsuction
We gently insert a medical vacuum to physically remove the wax, clearing a direct path down the canal.
Effective Treatment
With the canal clear, your drops can flow unobstructed to the eardrum, ensuring rapid and effective healing.
Why do my ears feel blocked after a cold?
A common search we see is "clogged ears from cold." This is usually caused by Eustachian Tube Dysfunction. When you get sick, the tube that drains your middle ear swells shut. This traps liquid behind the eardrum ("Fluid in ear").
While this feels like a wax blockage, the ear canal itself is often clear. We can confirm this using Video Otoscopy. If we see fluid bubbles behind the drum, we can refer you to a GP or ENT for nasal sprays or steroids to drain the fluid.
The Mechanics of a Blocked Ear
Healthy Airflow
The Eustachian tube is open. Air flows freely, keeping pressure balanced behind the eardrum.
Inflammation
A cold or allergy causes the tube walls to inflame and swell shut, cutting off the air supply.
Fluid Trap & Pressure
With no drainage, sticky fluid builds up. It pushes against the eardrum, muffling your hearing.
Why "Aural Toilet" is Critical
If you have an Outer Ear Infection (Otitis Externa), your GP will prescribe ear drops. However, if your canal is swollen shut or filled with infected debris (pus/skin), the drops cannot reach the infection.
Clinical Audiologists perform a procedure called "Aural Toilet." Using gentle microsuction, we remove the debris and open the canal. This allows the medication to contact the infected skin directly, drastically speeding up your recovery.
Treating an ear infection without cleaning it first is like putting a plaster over dirty skin. We clear the debris so your body can heal
