Tinnitus is a common condition characterized by the perception of sound in the ears or head, often described as ringing, buzzing, hissing, or clicking, in the absence of an external source. Although tinnitus is not a disease in itself, it can be a symptom of underlying health issues or a result of various factors. Understanding the causes of tinnitus is essential for developing appropriate management strategies and improving the quality of life for affected individuals.

Noise exposure, aging, and certain medications are among the most common causes of tinnitus. It can also be triggered by head or neck injuries, earwax buildup, or specific medical conditions like Meniere’s disease and acoustic neuroma. The condition may be temporary or chronic, and its severity can range from barely noticeable to extremely debilitating, depending on the individual and the underlying cause.
