Thanks very much for the insight.
I have gone for a numerous amount of heart and blood tests to rule out stroke and TIAs. All have turned up fine, however, I haven't gone for my MRI as of yet. It is scheduled at the end of the month, so needless to say that I am still a bit worried. I haven't had an 'episode' in over a month so I am feeling a little bit optimistic that it is an aura associated with migraine, but from researching and reading up on my symptoms, I am a little bit concerned about it being a brain tumor (maybe I am being paranoid).

What are the symptoms of a brain tumor? Are they similar to my 'episode'? I would think that if I did have a brain tumor my symptoms would be happening on a regular basis and be more consistent. I have read that the symptoms of a brain tumor are headaches upon waking in the morning, projectile vomiting, etc. none of which I have. Thoughts would be much appreciated.
Thanks very much,
