Hey!!! So, Don the Nurse called back and said (drum roll):
"We aren't sure if it's a sprain or fracture."
Well, I guess there is a "line" that could be a slight fracture OR could be a "growth line" meaning I did something to it long ago and the bone just regrew (???) whilst healing. They want me to follow-up with "my doctor" or an "orthopedic surgeon" (I bet they do), but in the meantime to follow the doctor that I saw on Friday's orders.
"Um..."I said. "She said to treat it as a sprain."
"Yes, that's sounds good!"
