Friday morning, she woke up fine! But as the days went on she'd have times off and on where she'd start running and end up hopping or just crawl to stay off it altogether. I finally decided yesterday to take her in and have it looked at, assuming she needed an x-ray. She was just acting too much like it was a stress fracture in the way it would be fine in the mornings and get progressively worse as the day went on.
Well, her pediatrician agreed. She said she has a mild stress fracture in her heel or ankle somewhere. The x-rays weren't clear enough to show exactly where, but she said it didn't really matter. Either way, she's in a boot for two weeks minimum, possibly four. We go back two days before her birthday for a recheck. I'm pretty sure by then she'll be fine as mild as it seems to be.
I painted it for her to help her like it. :) That plain old black was just too boring for this little girl. When I showed her this morning, she said, "Um, I wanted it all pink." Well, I tried. A can of spray paint seems a bit much.
