Have
you ever come out of a concert with your ears 'ringing'? If so
you'll know how uncomfortable it can feel. Unfortunately for
tinnitus sufferers, this sensation can be continuous. Tinnitus
is not a disease but a symptom caused
by a variety of other conditions. It affects around 7 million people
in the U.K and is common in all age groups. There are many people
suffering but don't know what it is or, more importantly, how
to deal with it.
Tinnitus
comes from the Latin word tinnire "to ring", which is a common subjective
description from those experiencing it. It has also been described as
a high pitched 'hissing', 'buzzing', 'whistling' or 'whoosing' sensation
in either one or both ears, but only heard by the sufferer.
These sensations can be intermittent (lasting only several seconds), continuous
(persistently there in the background and worse in a quiet environment) or pulsatile
(beating in time with your pulse). The loudness will often vary in its intensity.
The exact mechanism for how the noise is produced is not known. One theory is that injured cochlear hair cells discharge repetitively and stimulate auditory nerve fibres in a continuous cycle. Another idea is it can be due to spontaneous activity in individual auditory nerve fibres causing false information to be transmitted to the brain.
Managing the symptom is especially helped by figuring out what may be the underlying cause. It is advisable to seek the advice of a medical practitioner if you are unsure or worried and if your symptoms are persistent and disturbing your quality of life.
