So why would you think she would have been better off taking drugs against pain that she didn't have?
Real pain is treated here in Germany - of course!
But taking pills for mere fear of pain that isn't even there?
I had had four wisdom teeth removed all at once, that's when I got and took a few (a few!) Ibuprofen during the following week. Only because I actually lived and worked in the US at the time (but had the surgery done during a vacation in Germany), and had to go back to work, doing IT training for a few days. Otherwise I would have taken even less.
Later I had jaw surgery, lower jaw extension by 4 mm (no metal left inside me, by the way, it was a z-cut followed by the shift and half of a bone could reattach to the other half, just shifted lengthwise a bit), so a complete cut through the lower jaw. I did not need a single pain pill.
