Can doctors tell me what does persistent tinnitus indicate?

Tinnitus: Ringing in the ear can be high pitched or low pitched like a washing machine whoosh whoosh. It can be benign or can be worrisome. It can be caused by medications, inadequate hydration, brain abnormalities, or abuse to the ear (loud music/sounds). It can even be due to caffeine. Please see your doctor yo run the appropriate tests and look into your ear.
