What is tinnitus?
Tinnitus is a sound or sounds that you can hear in either your ears or head that other people cannot hear.
It’s usually described as a sound such as ringing, whistling, hissing or a roaring.
The medical word comes from the Latin word ‘tinnire’, which means ‘to ring’.
You might only notice these sounds when it is very quiet, such as at night. Or they might be so loud that they intrude on your everyday life.
Either way, tinnitus can be distressing and worrying – but you are not alone.
