Hi! Sorry this is going to be a fairly long post but please bear with me as I'm frantic. I have had off and on ETD/occasional PET. I have tinnitus for too many years & it mostly doesn't bother me. I get the occasional spike (goes incredibly loud and ear feels full and peters off) but twice since January I've had the oddest very scary episodes... Suddenly I get a low tone (like bass/vibration) tinnitus when I speak, my ears gradually feel incredibly full with this very loud tinnitus (my normal tone but much louder) then noises & my voice start to distort (it vibrates my head and eardrum, I can actually feel the ear drum flutter). I have no hearing loss. My ears look clear & eustachian tube works fine but it doesn't release the pressure. It gradually recedes over a period of about 6 hours. I contacted an ENT online who says it sounds like cochlear hydrops which has terrified me to be honest. Any thoughts??
