Background: Two weeks ago, DS1 and DS2 had what was diagnosed as croup. Fever, congestion, cough. I wound up with it and it was diagnosed as influenza, but they didn't swab me so I'm unconvinced. Regardless, it presented the same.
Now: Yesterday, DS1 (10yo) came home from after school activities with a bad headache. We gave him some tylenol and he took an uncharacteristic nap, then rallied and went to music lessons. No fever. Around midnight he woke up and vomited and had a high fever (103.6). Cleaned him up, a few crackers and tylenol, then back to bed. Woke up around 5:30 am with fever (102.6).
Now it's mid-morning and the tylenol has worn off - he's hovering about 100F. Stomach feels fine, mild headache. On the BRAT diet just in case (with oatmeal added in).
Does this sound like a gastro virus, or could the vomiting have been from the fever?
