That's awful, good thing you were calm that's exactly what she will have needed.
No idea where your head would have been at during that period as I think I'd have been fearing the absolute worse.
So she had neck spasms, jaw was stuck and tongue would be rigid to one side.
It was surreal in a bad way. Had to keep calm for her sake, let alone myself! Wouldn't wish it on anyone, horrible to see. Let alone for her to experience.
Doctors/paramedics/nurses all class though.
