A constant or recurring ringing, buzzing, humming, or hissing sound in your ears may be more than just a temporary annoyance. This symptom is commonly known as tinnitus.

Tinnitus can have many possible causes, including exposure to loud noises, age-related hearing changes, earwax buildup, certain medications, or problems affecting the ear and hearing system.

7 signs you shouldn’t ignore:

1. Ringing that persists for days or weeks.
2. Buzzing or humming that keeps returning.
3. Hearing loss occurring alongside the ringing.
4. Dizziness or balance problems.
5. Ear pressure or pain.
6. Ringing that matches your heartbeat — known as pulsatile tinnitus.
7. Symptoms affecting only one ear, especially when persistent.

Most cases of tinnitus are not dangerous, but persistent or sudden symptoms should be evaluated by a healthcare professional. Sudden hearing loss, severe dizziness, or new neurological symptoms require prompt medical attention.

Early evaluation can help identify the underlying cause and determine whether treatment is needed.
