Hi Bec,
My ENT ordered an ENG for me when I had my last flare-up. I had dizziness, so he wanted to rule out any middle ear problems.
The test is very easy, and it takes about 1 1/2 to 2 hours. Mine was done in a tiny office, not in a hospital. No gowns, just street clothes.
What it involves is placing electrodes/sensors around the eye area. These will measure eye movements as you watch stimuli. The eye responds to ear sensations like dizziness.
You are going to in a dark room with the person who gives you the test. Then, while sitting, you will be asked to follow these scrolling dots that will be moving right to left, then left to right. After that, they are moving from top to bottom, and then bottom to top.
The 2nd part of the test, is the repositioning test. You lay down with the tech assisting you, with your head hanging off the table. You are told to look to the right (or left), and then brought back into a sitting position. This is repeated for the opposite direction.
The last part is using both cold and warm air insterted into your ears (not at the same time). Each ear gets 1 minute cold, then 1 minute warm. Then you are asked to do a mental exercise between each session....like naming boys names beginning from A to Z.
I don't recall it being painful at all. Just time consuming. I failed the repositioning test. That is what sent me to the neuro. I was dx'd with vertigo as a symptom, and rx'd Antivert. It was my 2nd flare-up, and he also started me on Avonex weekly injections.
I hope this clears some things up for you. Wouldn't it be something if you have already had this done, and that it is fresher in your memory than mine, and you could tell me a thing or two!!
Jewel is right, they start eliminating other things to come to an MS conclusion, and that may take some time to figure out. MS is sneaky and puzzling. And when you are in "limbo", it can mess with your head!
All the best to you!!
