Tinnitus is a common condition characterized by the sensation of sound for which there is no external source outside the individual. In other words, people with Tinnitus perceive sound when no environmental or external sounds are present. These sounds have been described as clicking, buzzing, and/or ringing. Tinnitus commonly occurs as a side effect of certain drugs and because of other underlying disorders (secondary), especially those of the middle and inner ear (i.e., cochlea). In rare cases, no underlying cause can be found and the condition is termed "idiopathic" Tinnitus. Infection, obstruction of blood vessels near the ear, and/or environmental factors have also been implicated as a cause of Tinnitus.
