Does anyone else have a 24/7 ringing in the ears? (At times it is more of a roar, and at its worst, a whine.) For me, this is very pronounced during periods when my blood pressure is at its highest (180s), but since I developed unpredictable blood pressure (right now it's completely normal), it has always been present. Often, I think it will drive me insane--white noise at its worst. Am I nuts?
