If you've never heard things before, and you've recently started a new medication, I would bring it up to your PDOC. It might be a rare side effect or something. It would be nice if it's just a side effect and it will go away once you stop the med.

I don't hear things, but I see things out of the corner of my eyes. Figures and shadows that scare me. But when I turn, nothing is there. I've gotten used to it now and it rarely scares me but sometimes it still freaks me out.
