Tinnitus is characterized by noises in the ear(s), such as ringing, buzzing, clicking or hissing. These noises can range from low to high pitch. Severe symptoms can cause impaired concentration, inability to follow conversations, poor memory, poor sleep, extreme fatigue, depression, and anxiety. The condition is often accompanied by hearing loss and/or other ear, throat and nose issues. Even with treatment and therapeutic management, tinnitus can cause debilitating limitations and long term disability.
