Hi tcl16,
Welcome! It's kind of scary having symptoms and not know what is causing them. We all want a name to our problem. But, that takes time, like most people have already mentioned that fact to you. "Wait and See" is the hardest part.

Some wait for weeks, others for years. You have to try to forget the worry until you have cause to worry. It might be just migraine headaches with aura. Or it might be one of the 150 or more neurological problems/disorders that it out there. Some are minor. I hope your problem turns out to be minor.

Let us know if you have any more tests, or questions, and then when you see you Neuro what he says about his findings. Nice to meet you.
