Give your daughter hugs for me. That had to really hurt!!!
This reminds me of when my daughter was in college she was running from the car to the house she was renting on campus I the rain and stepped on something that went all the way through her running shoe.
She tried taking her shoe off but it wouldn't come off and thought she'd stepped on a nail. Had a friend take her to the ER.. When they looked at the bottom of the shoe they couldn't see anything, but also couldn't get the shoe off. Took an Xray that showed a piece of something stuck in her foot. They finally removed it and it was a stick that had gone between the ridges in her shoe and into her foot.
She also was on antibiotics for awhile.
No one in the ER had ever seen that before either.
Kids, gotta love em.
