Thanks for the info and encouragement I will get a second opinion after I see the ENT doctor if he doesn't find any cause. I think it's very strange that the neurologist doesn't want to find a cause, but I do understand that it's pretty smart to wait until you find out that it won't go away on its own to do extensive tests or something. (I have no idea what tests they'd do besides an MRI.) There are a couple other neurologists close to me, so it shouldn't be hard to find one.
