My 8-year-old daughter is in the hospital for the second time this month. First, Kidney infection, now suspicion for appendicitis, but they only found mesenteric adenitis. They are sending us home, but my daughter s pain hasn t subsided. Ct scan showed normal appendix. Ultrasound said intermediate chance of appendicitis because of fluid. She has vomited twice today. No fever. Pain lower right quadrant.
