i suffer with vertigo for several years then i went a while with out it and then it came back one last night and once so far this month and doctors never could figure out where it came from or where it comes from.

I rarely suffer from that too. One day, it lasted three hours and I could not stand. Spent the whole time vomiting (dry heaving) into a bucket. A month ago, it hit me at work and I "fell" into the wall. But it only lasted about five minutes.
