They are now on the way to Texas Children's Hospital, which is an excellent place.
If it were bone related, we'd see some red cell or blood calcium abnormalities, so maybe the pancreas... :(
Thanks so much for the wonderful well wishes. You bums are the best!
So far all of the worst case scenarios have been eliminated, so hopefully she will be fine. They are considering a possible viral or parasitic infection. I'd guess more tests are in the future. She got to go home in the afternoon.
