They definitely should have told you about all of that ahead of time!
Seeing as how, according to them, this is basically the only thing that can disqualify you from the procedure.... hell yeah they should have mentioned that.
I don't even know what a "good" BP is but it was nice to hear from my nurse sister than mine isn't actually bad.
No, I don't think it sounded bad at all. Better safe that sorry I guess though.
