Hi, I get this strange sound/sensation in the back of my head - ususally when im really hungry. Its almost like a fizzing, sizzling sound - or like the sound of rainsticks (if youve heard them). its high pitched and doesnt last long. Ill often have them when i wake up in the morning and im hungry. It doesnt sound like bones cracking or popping or anything - sounds more like a liquid squeezing through a small hole or something, right at the base of my skull, or back of my throat. Any idea what it could be?
