###Human: My hearing is affected after suddenly waking up in the morning with dizziness and nausea. Please help. ###Assistant: Hi, Welcome to iclinq.com. You need to perform tympanometry and pure tone audiometry to assess the condition of your middle ears, inner ears, and cochlear nerves. The attack which you have experienced can be an acute vestibular attack but the accurate diagnosis needs initially the previous audiological investigations plus videonystagmography (VNG). Before audiological tests, you have to stop any medications for dizziness for three days.
