I am so sorry you went through this. My sister had a similar experience where she was awake and in pain. My other sis who is a nurse told me to speak with the anesthesiologist and specify my desire to be completely out. I did and my experience was as follows.
Doc: I am giving you the med to put you asleep, it might feel warm
me: How long does it take?
Doc: Wake up now, the procedure is finished, would you like a drink?
It sucks that the med profession would operate so poorly and be so insensitive. I will be extra careful that I am explicit moving forward. Truth is, if I was awake I would be making such a fuss they would put me to sleep, even if they had to knock me on the head to do it.
