This morning my 9yo daughter was fine. By 11am she was asleep, strange... tried to feed her lunch, she wasn't hungry so I took her temp. It was 101.5 so I gave her Tylenol. She sipped water and gingerale. At 2pm she complained that her head hurt, pushed more fluids. At 3:30pm she was almost in tears over sudden mid-low back pain. It doesn't seem as bad when she lays down, but sitting is painful. It's too soon for more Tylenol and recheck of temp shows 100.5 and I am a little comcerned. She can touch chin to chest, yeah checked that. Anyone know what's up? Should I continue home treatment? Or is this urgent?
