Definition

Tinnitus is the perception of abnormal ear or head noises. Tinnitus is unpleasant enough itself, and is sometimes a symptom of other problems, including hearing loss , tumors, and narrowing of the blood vessels. Noises may be high pitched and “ringing,” or sound more like a clicking. Some tinnitus is pulsatile, which means it may be caused by the flow of blood that accompanies each heart beat, and this happens in cases of narrowing of the blood vessels.
