7 year old son with recurring fever

[Oliver5]

My 7 year old son has had recurring high fevers every 3 to 5 weeks that last from 2 to 4 days.  (This past fever is the 5th one that has occurred).  He has been diagnosed and treated for strep and sinus infections, but nothing more.  The doctors have tested for mono, pneumonia, lyme disease - all which were negative.  What could possibly be wrong?  He has no other symptoms aside from the high fever. Any ideas would be appreciated.

I have a 7 yo girl with the same problem....and I am sitting here in the middle of the night to find answers, and she is sleeping  (finally) with a temp of 103.5F.... we are "regulars" at the ER or Dr's office for the same reason.
Nothing have been found. they look at me like I have Munchhausen by proxy. I am far from it!
...and I am very frustrated!
she has this episodes about every 6-8 weeks. only the high fever...what the hell is it?!
I was a nurse in my home country, Hungary, and there the child stays in the hospital, until they FIND the reason.

I have 2 sons that got high fevers.  One got a high fever and a severe stomach pains.  It would last 2 to 3 days then go away a month later come back.  He was about 7.  He was even hospitalized for 2 days once for it.  It finally went away and never came back.  He is now 15.  I also have a 5 year old that would spike fevers when cutting his molers.  I hope you all find out what is going on.  

All of you will be in my thoughts a prayers.

I am a newer pediatric occupational therapist, that helps with early intervention in the home.  I am wondering if anyone has found any answers to any of these comments as of today.  I am currently working with a mother whos 2year old has a fever of 104-105 every 3 or so weeks.  That is his only real symptom other than an occasional hoarse sounding voice.  He is displaying signs of aspergers but has not been offcially diagnosed.  The doctors suspect a bacterial throat infection, but they can't find it.  I cant help but think it is some major allergy problem, but do allergies allow a 105 fever?  They live in a small home with several kennels of dogs in the home and I have spoke to the family about how this could be a major cause, but I am not sure.  I would love to get anyone's input.

This caught my eye, I have a 4 year old daughter who has been through the hoops with testing. She will spick a 106 fever for no reason about every three weeks. This went on for a year and half and now she will get a low grade fever and have a seizure from it. I can understand the frustration, it has be hard on her. The only thing we have found is sinus problems and she takes allery medicine and it is the first thing in a long time that has helped. Now she has blood in her urine and have no idea where that is coming from. I almost need to hear a sound problem, it would at least be easier to handle.
