for a few days now I've been hearing a strange noise.. it sounds almost like a muffled maraca in my head just shaking twice in a row like "fshunk-fshunk" and then everything around me moves to the left really fast. I either move with it or against it, and end up tipping over. I feel as though this is vertigo, but nothing about the strange noise is listed anywhere. It's almost the same sort of... noise as a ringing in your ear.. like it's coming from the same place as that, but it's definitely a maraca-ish sound.. it's hard to describe.. I was just wondering if that was vertigo..
