Hi,
Does VERTIGO while strong blowing of the nose (especially by blocking only one nostril) cause PERILYMPHATIC FISTULA?? I had the first experience of VERTIGO a few days back which lasted for about a minute. Am i at risk ?? I had done a Tympanometry for both ears - but did not feel any Vertigo due to pressure fluctuations. I am anxious after reading several posts online stating that - VERTIGO while blowing nose can be caused by PERILYMPHATIC FISTULA.
