Hi, sorry to read about your episode.
There's so little the layman can say, and you seem to be fast-tracking the medical system, and that's good. I'm a tad concerned the guy made the assumption of blockage rather than bleed. So difficult, and he's gone the logical route, but I'm just not sure about sending a case like yours home with some pills. But still, the symptoms seem to be fading, and the vessel scan is really good news.
License? You should tell the folk in the big grey cube.
I often think laterally to the point of absurdity, but is there anything you could have eaten that might contain some exotic drug? Raw fish from the the far east comes to mind. It's so odd that the symptoms covered such a wide area, yet left so many other functions unaffected.
Keep us informed.
