Ask the doctor: Ringing in the ears
Q. Over the past few months, I have noticed a constant low-level ringing in my left ear. How can I make it stop?
A. It sounds like you have tinnitus, caused by a malfunction in the hearing nerve, either from loud noises or age-related changes. Pulsatile tinnitus, in which the sound changes in time with your heartbeat, is a special situation often related to blood vessel problems.
