If you can get the ct scan quickly and it has been suggested I would certainly go ahead and get it. Any of the docs test electrolyte or mineral levels? It's amazing the type of symptoms that come on when some of those things are out of whack. It could be so many things - I have severe neck problems and it causes vertigo, eye & ear pain, sinus pressure and a few other symptoms I would have never attributed to neck problems. You have to be diligent and just keep asking questions if you feel you aren't getting answers! Good luck!
