my oldest son got the flu and ran a fever of 102. 7 accompanied with some vomiting. my youngest son started running a fever about a day after my oldest stopped showing symptoms. my youngest (9) never got a fever past 100. 7 but was just as achy with some nausea. we treated him for the flu also. it lasted no longer than 2 days(fever) and the coughing stayed for right at a week. they both recovered at about the same rate. this could be what is happening. fever reducers would help but only slightly and didn't last but 30 mins to an hour. we got tamiflu from the doctor for my oldest but used over the counter for my youngest and it seemed to work just as good. i hope this helps and hope they feel better soon!
my 4 year old son has been running a fever of 100. 5 and now has a bad cough he says that everything hurts
