This article explains how a woman was able to hear the sounds of her muscles moving e.g. eyes, swallowing, chewing, etc. She endured this for 7 years. The problem came about from fluid leaking from the superior canal (one of the semicircular canals of the balance system) and this fluid was thinning the bone around the ear. A surgeon corrected the problem by filling in the holes in the bone. http://www.optuszoo.com.au/news/top/news-com-au/woman-can-hear-her-eyeballs-move/935524 Wallflower
