My daughter is 11 and has been having abdominal pain , loss of appetite , diarreah , headaches , no fever present for 9 days. She has been to the ER and had a ton of blood tests done. Everything has come back negative and she was sent home. Again, vitals all good. This morning she has a swollen right temple and right side of her head and under her eyes. She said her stomach still hurts and hasn t gotten out of bed except to use the bathroom since last Thursday. Any ideas?
