Ear Symptoms That Should Send You to a Doctor

Most hearing change is gradual and can wait for a routine check. A short list of symptoms cannot.

Age-related hearing loss usually affects both ears equally and comes on slowly.¹ That pattern is the reason it is safe to handle through a routine check. Symptoms that break the pattern are the ones to act on quickly.

See a doctor promptly if you notice

• A sudden change in hearing, in the past days or months.
• Hearing that is much worse in one ear than the other.
• Ear pain, or fluid, pus or blood coming from the ear.
• Significant ear wax build-up, or a feeling that one ear is blocked.
• Dizziness or vertigo.
• Ringing or buzzing in one ear only.

This list comes from the FDA's consumer guidance on hearing aids, which uses it to define who should see a doctor, preferably an ear, nose and throat specialist, before considering any hearing device.²

What a hearing evaluation involves

An audiologist or ENT will look in the ear canal, ask about your history and any medicines, and run a hearing test in a quiet booth. The result is an audiogram: a chart of the softest sounds you hear at each pitch, for each ear. From it the clinician can say whether loss is present, whether it is mild, moderate or worse, and whether something that can be addressed, such as wax or fluid, is contributing. The NIDCD suggests a primary care doctor, an otolaryngologist or an audiologist as the right people to see.¹

What happens next depends on the result

Causes such as wax or fluid are dealt with by the clinician. For long-term age-related loss, options range from hearing aids fitted by a professional to, for adults with perceived mild to moderate loss, over-the-counter devices sold without a prescription since 2022.² Whatever the route, the evaluation comes first: it is the only way to know which category you are in.
