Over the next few days, things felt much better. My foot was still sore when I walked, but less so each day, and no discomfort at all when sitting or lying down. So, I figured it wasn't broken. But best to be safe, so I made a doctor's appointment. I just got back.
There really isn't much pain at all, just sore when walking, which requires a little limp. But I have to wear this sandal-like protective shoe for the next three weeks, and then probably another 2-3 weeks after that.
It's my fondest hope that that I can parlay this isn't a lot of sympathy from people, which might make this all worth it, particularly given that the sympathy to pain ratio would be so high.
One thing I learned -- it's good to put your suitcase away as soon as possible.
