Tinnitus

 (“TIN-a-tus” or “Tin-EYE-tus”) is the medical term for the sensation of hearing sound in your ears or head when no external sound is present. It’s commonly described as “ringing in the ears.” However, for some people it may sound like hissing, buzzing, whistling, roaring and even chirping.  The important thing to know is that tinnitus is not a condition or a disease. Instead, it’s a symptom — typically of something bigger, like an ear infection, high blood pressure or, most commonly, hearing loss.
