Hi Chris,
I too have never heard of the term
vascular vagal, but I have heard many people say that after their surgery they could not speak, write or even form words they wanted to say, etc., for a brief time after their surgeries. So perhaps others experienced the same or similar thing you have, but never heard it put in those technical terms before. (??)
When I looked it up, I read a lot of medical jargon I didn’t understand. It said,
vagal is pertaining to the vagus nerve, meaning wandering, blah, blah, blah, and the more I read, the more foreign it was to me, and way out of my league of understanding. So, if I were you, I’d ask my doctor to explain Vascular vagal in simpler terms, (if he can) to see if anyone here would better relate to that experience under those terms. I also saw the definition Stephanie explained, (good job Steph!)and wondered if your doctor means it was an anxiety type of episode. (??)
