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
