Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. F.  It appears that he had a fever of intestinal origin, probably enteric fever. That is why he had stomach pain followed by fever. It also will have sneezing and cough as well, which in turn will have upper respiratory tract like symptoms and nose bleed etc. I advise you to consult a pediatrician for diagnosis and treatment. He may have to undergo series of blood Tests for confirmation.  Wishing for a quick recovery.  Best regards.
