I've been following this thread withn increasing concern... Before I started my PPL training I asked if migraine would prevent me passing my medical. I was assured that it wouldn't be a problem - and it wasn't. Some 12 years on, I'm still flying and still get the occasional migraine, nothing like as bad as in earlier years, and of course I wouldn't fly if one occured before I departed. So far I have never had an attack whilst flying.
I recently stopped (on the doctors instruction) my 2.5mg bendro. tablet for mild hypertension. Around the same time it was my turn as President of the local Rotary Club. Soon after, the migraines returned, as often as twice a week. My BP had gone up considerably, so I went back on the tablets, and the problem went away, with BP back down to a more acceptable 127/70.
I found this link:-
Migraines: Myth Vs. Reality which confirmed the link between strokes & migraine as metioned by LR.
I hope that you sort this out, AnthonyGA and that you can carry on doing what we all love to do. RF
