What is Tinnitus?

Tinnitus is the perception of sound, such as ringing, buzzing, or hissing, in the absence of any external noise. It can affect one or both ears and range from a mild, occasional annoyance to a persistent, distressing symptom.

It's often linked to hearing loss, exposure to loud noise, earwax build-up, or age-related changes, though sometimes no clear cause is found. It's rarely a sign of a serious underlying condition, but it can significantly affect quality of life and sleep if persistent.
