Tinnitus is the conscious awareness of a sound that is not due to an external source and affects about 1 in 8 of the population.
Tinnitus is rarely a sign of a serious underlying condition.
For some people it may come and go and only be a minor irritation.
However, it can sometimes be continuous and have a significant impact on everyday life.
Severe cases can be very distressing, affect concentration and cause problems such as difficulty sleeping (insomnia) and depression.
