My current frustration which is that in addition to living with this very loud high pitched ear piercing tinnitus since November 2013, I've developed low pitched tinnitus as well, a completely separate tone, also on both sides. It's a low E (on the guitar) but isn't musical in quality. It's loud, constant and thunderous, like a plane that never flys away but stays nearby. Very ominous and frightening sounding. I was nearly habituated to the high pitched scream and doing quite well when this second tinnitus hit about a month ago. Oddly, when the docs told me that I had hearing loss at high and low frequencies that was causing my tinnitus, I wondered why I only had high pitched tinnitus.... That was apparently temporary! Anybody else have 2 completely separate types of tinnitus simultaneously?
