i had similar symptoms due to a tear in the membrane of the inner ear called a perilymph fistula...my tear was so large it leaked CSF (spinal fluid) your GF's symptoms sounds identical to mine only i was sentitive to sound and my sensory was distored due to the ear/vestibular issue, i would look down this path...most doctors don't have a clue about it so you have to be pushy and do your own research, best of luck
