Tinnitus is a condition characterized by the perception of noise or ringing in the ears when no external sound is present. It is not a disease itself but rather a symptom of an underlying issue. Tinnitus can be caused by various factors, and the exact cause may vary from person to person. Some common causes of tinnitus include exposure to loud noise, earwax blockage, age-related hearing loss, head or neck injuries, and medications. It's important to note that in some cases, the exact cause of tinnitus may be challenging to determine. If someone is experiencing persistent or bothersome tinnitus, it is recommended to consult with a healthcare professional, such as an audiologist or an ear, nose, and throat (ENT) specialist, for a thorough evaluation. Treatment options may vary depending on the underlying cause.
