I also have vertigo but it only happens when a very something speeds by me very fast. Like a train. Also only sometimes..... usually when my darn sinuses are acting up.
I also have delayed hearing. What is that you ask? Ok its this....you say something to me and it takes me a minute to hear you. Very strange thing to happen. I asked my doc about that once. I have nerve damage in my ear so its not as rare as you think. he says that the brain "hears" the sound 1st then it reaches your ear and presto you hear something. Well when you have nerve damage the the sounds get haywire before it reaches your ear...hence the delay. Its funny when when i tell people to wait a minute and then I'll hear it. This also happens at least once a day.
