You will get a local , but you have to be awake so they can place the tube in the throat. You have to be able to swallow to get the tube down so they can do the upper GI!
Yes, Your throat will probably be sore when the local works off. It is something that is not normal there.
Hell, I have been hacking so much crap up with what ever I have, I cant breath, get head aches and blood vessals pump like I am dieing!
This really is a peice of cake!
Try 3 Butt Octomys in 5 Days, that is a real Trip!
