Hi,
Not being one of you pilot chappies.............i'm a girl anyway and not a chappie, I dont know anything about the medicals.
However, I am medically trained and a migraine sufferer.
I dont know what causes mine either, other than stress or lack of sleep.
Eye strain can also trigger an attack.
No-one can say that you are likely to or unlikely to get one again no matter what tests you have...........dont waste your money on that score.
Beta Blockers can be used prophylactically................eg, Propanalol, would they be allowed to be taken.
I take Sumatriptan tablets at the onset of an attack, they are only available on prescription, but they work, very quickly and prevent a full blown attack.

Hope this helps.
