Tinnitus is a symptom where the patient hears a noise in one or both ears. The noise heard can be loud, shrill, a hissing sound, or anything else. This persistent noise can add to stress levels and make it difficult for patients to hear and communicate with others. Tinnitus is a symptom caused by various underlying conditions. However, the cause is often not identifiable and, therefore, tinnitus cannot be cured. However, tinnitus can be managed and treated so that patients are better able to cope with the noise they are hearing.
