GI. N/V, diarrhea, abdominal cramping x 4 quadrants, chills/rigors, severe headaches, fluctuating (with admin. Ibuprofen and Tylenol)temp. 99-101-102.4 F for about 32-36 hours. Onset seemed to be sudden. Was at theme park in Chicago 2 days ago; around lots of people, ate at various places. No one else in our party is ill. My question: manage at home? See her pediatrician? Request medium(s) for stool testing? other? Thanks
