Hello??!! You do have a pediatrician, don't you? You have a child with that high of a fever and you bring it here instead of calling the doc? Parenting fail of the day (to say the least)...or another sick attempt at trolling.
My little bro had the same thing for 3 days, his temp. ran 102 to 104 and only went down when given Ibuprofen but still it stayed in the 100s and kept shooting up again to 102 to 104 when the Ibuprofen wore off. My mom took him to the doctor and it turned out to be pneumonia and he had to take antibiotics for 5 days. You should take him to the doctor just to make sure he doesn't have the same thing.
