I have the sound of a car horn going off right by my ear, which used to be very disconcerting ! It only happens when my BG is going low, not only for hypos, but heading that way too. It lasts until my BG is in my normal range
I have been told this is tinnitus, but it sounds completely different from what my experience of tinnitus is
Its a pain in the butt, but it also serves as a warning before hypo warnings as it were. A hippy chick friend said it sounded to her as if my " Guardian Angel " was sounding a warning, if it is, the GA has a wicked sense of humour as well as not so much a golden trumpet, but a ruddy great klaxon
