I felt a flash of pain and then nothing. When I looked down my big toe was bent over the other toes and my foot looked kinda weird.
Just at that moment, my wife called out that our 2 year old was missing. We looked around and when no one could find him she went up the beach one way and I went down the other, hobbling along as fast as I could. As it turned out, I went the wrong way, and as I don't give up easily, I went a mile or so. On the way back the foot was throbbing like hell, but the toe still didn't hurt.
The doctor who looked at my x-rays said that she stopped counting individual fractures at 25. She said the walking I did probably severed some nerves. A few months later, I started falling when the foot just wouldn't work right. After falling down the stairs I went back and had surgery done to free up the nerves. That foot is about a size smaller than the other now, and I have a nice 5-inch scar and a weird looking big toe.
So, no more sandcastle competitions for me.
