It's good that he is not crying nor lathargic, but I would call the Dr. and see what they say. Does he have a fever? My son at age 7 had those symptoms, and the Dr. told me it was the flu and to wait it out, well after about 3 days he got the rash, and I knew somthing was wrong. I took him to a Redi Care and he was diagnosed with Scarlett Fever.
