Tinnitis

[Hopeful]

Ok, I know that cancer drugs can have some weird side effects, but has anyone noticed ringing in the ears from Herceptin or AI's? This is one that has been creeping up on me for the last several weeks, to the point where it is now constant. I only really notice it when there is absolute silence in the room, but it makes it hard to get to sleep without leaving the tv on low (at least mine has an automatic timer on it.) Is this, literally, all in my head?

Thanks,

Hopeful
