My daughter has been doing this for the last 1.5 years and she is only about to turn 2! It was so frustrating that we could not find anything wrong with her with all the blood tests, urine tests, CT Scan etc.... Finally I found out what the problem is.... allergies- Took a year to get this diagnosis!
When she is exposed to a trigger she will occasionally flush and then run a temp all the way to 104 and then come back down to normal within a day or two! Sometimes she would sit there and hold her head also for days and cry like she was in pain but not like a cold or the flu- if that makes sense! Several times she has also ended up in the ER with hypothermia because after the fever she would drop to 91 degrees and barely breathe. She was in anaphylactic shock. I could write a novel on what we have been through with this all! lol
My daughters triggers are unknown (she has Mastocytosis) so to avoid this and other systemic reactions including anaphylaxis we have been giving her daily doses of Zyrtec. She rarely gets the fever anymore- except today :) she no longer refluxes, no more severe pain, no headaches etc!
I would keep a diary if you do not want to do the Zyrtec and see if there is any common thing eatten, weather, activities, places you are at etc.
I hope you get to the bottom of this since it is soooooo frustrating as a Mom to not be able to do anything to help! Especially when we live in a world of information and you want answers!
Good luck and many blessings to you and your son!
