How far are you from a teaching hospital or a large hospital like one of the Mayo clinics? These places are often great at diagnosing and will run many tests in a few days. It is a good way to get answers without having to wait weeks or months between tests, visits etc.
When I went to the Rochester Mayo, which depending where you are in Canada, might be your closest, they ran 4 straight days of testing. It was all coordinated so I could just go from one to another.
Then you meet back with the neurologist and he will go over all of the test results with you.
They will give recommendations that you can bring back for your own Dr. and there is a pain management clinic there as well.
You don't have a diagnosis yet --right??
