Reluctance to walk (possible bone lesion), weight loss, poor appetite, etc over the course of 2 weeks makes me worried about malignancy. When I read bluish discoloration under eyelids, I think of neuroblastoma (case files says it's due to orbital involvement of the neuroblastoma).

There's no obvious indication that the kid has a bacterial infection that warrants treatment (purulent discharge, ear infection, pharyngeal exudate, etc). WBC is normal. At this point, just control the fever with tylenol.
