Unilateral Ear Itch Symptoms, Causes & Common Questions

4 Possible Unilateral Ear Itch Causes

The list below shows results from the use of our quiz by Buoy users who experienced unilateral ear itch. This list does not constitute medical advice and may not accurately represent what you have.

Swimmer's ear (otitis externa)

Swimmer's ear, or otitis externa, is an infection of the canal which runs from the eardrum to the opening of the ear.

It is caused by anything that introduces bacteria, fungus, or a virus into the canal. Water that stays inside the ear after swimming is a common cause, as are cotton swabs used for cleaning or earpieces that create irritation.

Most susceptible are children, because they have narrower ear canals that do not drain well.

Early symptoms include redness, itching, and discomfort inside the ear canal, sometimes with drainage of clear fluid.

Even mild symptoms should be treated because they can quickly get worse. The infection can spread and intensify, becoming very painful with increased drainage, swelling, fever, and loss of hearing.

Diagnosis is made through patient history and physical examination of the ear canal. Lab tests may be done on a sample of the discharge from the ear.

Treatment includes having a medical provider clean the ear canal of debris and discharge, and a prescription for antibiotic and/or steroid eardrops.

Rarity: Common

Top Symptoms: fever, ear canal pain, ear fullness/pressure, jaw pain, ear pain that gets worse when moving

Urgency: Primary care doctor

Earwax blockage

Ear wax production is a normal process, as the body makes wax to protect the ear from infection. Sometimes ear wax can build up and cover the eardrum, which is a thin layer of skin that stretches across the end of the ear canal and picks up sound from outside. Ear wax buildup has nothing to do with poor hygiene, and it is not possible to prevent a build-up by washing.

Rarity: Uncommon

Top Symptoms: dizziness, dry cough, ear canal pain, ear fullness/pressure, ringing in the ears

Symptoms that never occur with earwax blockage: swollen ear, fever

Urgency: Phone call or in-person visit

Chronic earwax blockage

Earwax production is a normal process, as the body makes wax to protect the ear from infection. Sometimes ear wax can build up and cover the eardrum which is a thin layer of skin that stretches across the end of the ear canal and picks up sound from outside.

Rarity: Common

Top Symptoms: dizziness, dry cough, ear canal pain, ringing in the ears, ear fullness/pressure

Symptoms that always occur with chronic earwax blockage: ear canal pain

Symptoms that never occur with chronic earwax blockage: swollen ear, fever

Urgency: Phone call or in-person visit

Allergic contact dermatitis of the ear

Allergic contact dermatitis is a condition in which the skin becomes irritated and inflamed following physical contact with an allergen. Common products known to cause allergic dermatitis include plants, metals, soap, fragrance, and cosmetics.

Rarity: Common

Top Symptoms: ear itch, ear redness, scabbed area of the ear

Symptoms that always occur with allergic contact dermatitis of the ear: ear redness

Urgency: Self-treatment
