Not exactly the same thing but my wife had a C section, spinal block did not work, she was feeling everything, they had to put her under. I didn't like any of that, I can imagine what you were going through.
My wife had a similar experience. I was in the delivery room with her. They start to do the spinal block her leg starts twitching out of control. "Is her leg supposed to be doing that?" I ask. Gas passer mutters "Oh ****".
