Many people across the world suffer from Tinnitus, and this can be heard in the ears or head as a continuous ringing, buzzing, hissing or similar sound that never seems to go away. Tinnitus can leave the sufferer feeling isolated and alone with their problem as other people cannot hear these sounds, or understand what it is like to live with day in and day out. This can often lead to the sufferer experiencing emotional stress such as frustration, fear and anger, as well as interfere with their sleep and general well being. Often it can lead a person to become withdrawn from social situations, and can trigger depression. Stress is a major contributing factor towards making tinnitus symptoms worse, so sufferers can end up in a vicious circle.
