Ear infections remain one of the most common and uncomfortable health issues affecting people of all ages. When left untreated, these infections can lead to significant pain and potentially permanent damage to the outer, middle, or inner ear. This comprehensive guide explains the causes, symptoms, and current treatment options for ear infections.

What Causes Ear Infections?
Ear infections can affect different parts of the ear structure, with varying causes and symptoms depending on the location.
Outer Ear Infections (Otitis Externa)
Outer ear infections affect the ear canal and are commonly caused by:
- Bacterial or fungal growth on the skin of the ear canal
- Water retention in the ear canal (commonly known as “swimmer’s ear”)
- Trauma to the ear canal from objects like cotton swabs or fingernails
- Skin conditions such as eczema or psoriasis affecting the ear
Common symptoms of outer ear infections include:
- Intense pain that worsens when touching the ear
- Redness and swelling of the ear canal
- Persistent itchiness
- Discharge from the ear (clear or pus-like)
- Temporary hearing reduction or muffled sounds
- Pain that may radiate to the jaw or neck
- Fever in severe cases
Middle Ear Infections (Otitis Media)
Middle ear infections typically develop when fluid accumulates behind the eardrum and becomes infected. This accumulation occurs when the Eustachian tube—connecting your middle ear to your throat—becomes blocked or inflamed.
Common causes of Eustachian tube blockage include:
- Respiratory infections (colds, flu, COVID-19)
- Seasonal or environmental allergies
- Sinus infections
- Exposure to tobacco smoke or air pollutants
- Changes in air pressure (especially during air travel)
- Excessive mucus production
- Enlarged adenoids (particularly in children)
Middle ear infection symptoms include:
- Ear pain or discomfort, especially when lying down
- Temporary hearing impairment
- Sensation of fullness or pressure in the ear
- Fluid drainage from the ear
- Fever (especially in children)
- Irritability and sleep disturbances in young children
- Balance problems
Inner Ear Infections (Labyrinthitis or Vestibular Neuritis)
Inner ear infections occur when viruses or bacteria infiltrate the fluid-filled chambers of the inner ear. These infections often have more serious implications for balance and hearing.
Key symptoms of inner ear infections include:
- Sudden hearing loss (requiring immediate medical attention)
- Persistent tinnitus (ringing, buzzing, or hissing sounds in the ear)
- Severe vertigo or dizziness
- Nausea and vomiting due to balance disturbances
- Difficulty maintaining balance or walking
- Sensation of fullness in the affected ear
Who’s Most at Risk?
Children, particularly those under five years old, are significantly more susceptible to middle ear infections because:
- Their Eustachian tubes are shorter, narrower, and more horizontal
- Their immune systems are still developing
- They’re more frequently exposed to respiratory infections in daycares or schools
Important note: Infants under 6 months who exhibit fever and signs of ear discomfort (such as ear-tugging or excessive crying) require immediate medical evaluation.
Modern Treatment Approaches for Ear Infections
Treatment strategies vary based on infection location, severity, and patient factors:
Outer Ear Infections:
- Careful cleaning by healthcare professionals – see your GP in the first instance
- Antibiotic ear drops, often combined with corticosteroids to reduce inflammation
- Antifungal medications for fungal infections
- Pain management through over-the-counter analgesics
- Preventive measures including keeping ears dry and avoiding ear canal trauma
Middle Ear Infections:
- Observation approach for mild cases (particularly in children over 2 with mild symptoms)
- Antibiotic therapy for severe or persistent infections
- Pain management with over-the-counter medications like acetaminophen or ibuprofen
- Warm compress application to the affected ear
- Decongestants or antihistamines for cases related to allergies (though evidence for effectiveness is limited)
Inner Ear Infections:
- Prompt medical attention is critical, especially with sudden hearing loss
- Vestibular suppressants for severe vertigo. Anti-nausea medications can also help if you are feeling nauseous
- Antiviral medications when a viral cause is suspected
- Corticosteroids to reduce inflammation
- Balance therapy for lingering vestibular issues
When to Seek Medical Attention
Contact your healthcare provider immediately if you experience:
- Sudden hearing loss – if you act within 24 hours, you may be able to have treatment to restore the loss
- Severe ear pain
- Symptoms that persist beyond 2-3 days
- Discharge of fluid, pus, or blood from the ear
- High fever accompanying ear symptoms
- Dizziness or balance problems
- Facial muscle weakness
Preventing Ear Infections
Reduce your risk with these preventive strategies:
- Practice good hand hygiene to prevent respiratory infections
- Stay current with vaccinations, including flu shots and pneumococcal vaccines
- Avoid tobacco smoke exposure
- Breastfeed infants when possible (breast milk contains antibodies that help prevent infections)
- Maintain proper ear hygiene—dry ears thoroughly after swimming or bathing. We also sell Dry Ears spray at Hearing Sense to keep water from accumulating in the ear canal
- Use ear protection when swimming, especially in lakes or non-chlorinated water. Swimmers Putty can work well or we can make custom swim plugs at Hearing Sense
- Manage allergies effectively with appropriate treatments like antihistamines or nasal sprays
Professional Hearing Health Assessment
If you’re concerned about recurring ear infections or experiencing hearing difficulties, a comprehensive hearing assessment is recommended. These evaluations can detect early signs of hearing damage and help prevent further complications from chronic ear infections.
