Yeh I can see your point. If someone diagnosed migraine in myself, it wouldn't matter a hoot, for you guys, it could be a disaster.
Although it's good news that the tests are normal, you are now venturing into one of the most dangerous aspects of medicine - expert opinion.
It's important that your neurologist knows about the impications for your career. Unfortunately, what will twitch the guys at the CAA is the fact that your limbs were involved. On your side is the fact that you have been thoroughly investigated, and your symptoms appear infrequent and transient.
Good luck.
