This is all correct, but might be rude in context. You have no idea if the epidural in the story above was medically necessary (many are), so replying with a post about voluntary procedures could be interpetted as subtle victim blaming.

My wife and I could not have done more to avoid medical interventions during the birth of our child, but the baby was facing the wrong way and an epidural was necessary to allow the midwife an opportunity to turn it. Thankfully the epidural was done properly.
