While I was pregnant with my twins, my vertabrae kind of squished together, and when they tried to give me the spinal, the anesthesiologist couldn't find a space between them. He kept sticking me in the spine. It was so painful I thought I was going to die, and I think I would have been glad to at that point.
Later, after the whole thing was over, a student nurse sat me straight up in bed to recover. I kept getting woozy and dizzy and sweaty. DH knew something was wrong and went to get a nurse, and when she saw me sitting up, she got angry at the student nurse and put me back down flat on my back. She told me you should never sit straight up after a spinal because you can leak spinal fluid. Once I was flat I was fine. It was really weird. It didn't help that they put me to recover in an old, tiny room that was being used as a storage closet for the janitors. When I had my C-section, there were 13 other women giving birth at the same time, and there wasn't anywhere else to put me.
At least I got 2 healthy, beautiful, tiny daughters out of it so that makes it all worthwhile!
