My x got an epidural when giving birth to our son. They got done and left the room, saying "we'll be back in a few to check on you ".
It was only a few minutes before I looked at the IV machine driving the drip. It had two sides to it. One going to the bag hanging on the left and one to the right. I don't remember which side, but one wasn't lit up. Like only one side was doing anything.
Two nurses came in about 15 minutes later and I said "I don't know, this may sound stupid but shouldn't both sides of that be 'on' ?".
They looked back and forth from me to the IV and each other. One got a panic look on her face and the other looked really pissed off. "We'll be right back" the pissed off one said and left the room.
After two more minutes, the Dr and both nurses came back in. Dr says with a annoyed tone, "we have to do this again".
Had to roll her on her side, take out the first one, pick a new spot and jab her again.
All three stood there and watched a third nurse start the machine.
Lots of fun that day./s
But seeing my boy come into this world, made it all worthwhile. For me anyway, I wasn't in any kind of pain.

Turned 50 yesterday, and I'm nowhere near retirement.
Good luck, my tots and pears go out to you...
