I'm not sure. It seems like when I started (4 years ago), I ended up getting some lab tests, and MRI, and some medication to try and help to migraines. Sorry I'm not more help, it was just so long ago, I just definitely remember the lab and MRI. i also know he did a test where he had me follow a stick back and forth with my eyes, put a flashlight by my eyes, did knee and hand testing where he popped them with some kind of instrument. He still does those test.
