My Daughter Is In The Hospital With A High Fever

My daughter is in the hospital with a high fever abdominal/lower back pain. She just passed a kiddy stone the other day and now has high white blood cell count. They think they see something in the ultrasound & now doing another one. Meanwhile, having her walk & then taking vitals.
I'm at home with my other kids & my ex-wife is there with my daughter. I'm in the dark ...
Any ideas???
