6 year old has had a high fever off & on for 3 weeks & refuses 2 eat anything. What can I do?

You have to go back to the doctor's. Seriously, camp out there. Talk to everyone in the waiting room how the doctor's have let this go on for 3 weeks. It's not good for anyone to have a high fever for so long. I hope you're replacing fluids with Pedialyte.

She could be teething, have you tried a diffrent doc....Second opinion, maybe its her stoamche an infection, fever points to infection. Just try to keep the fever down and take her cool baths.

go to the doctor

You are so lucky to keep her alive. It is in fevers like Scarlet fever where a child can lose sight or hearing or even life from the viral fevers. The spinal meningitis fevers are almost certain killers for babies.

that is scarlet fever i had it when i was young u are doing the best u can cos she is alive with a fever that high for this long try giving her ice-cream of mr freeze drinks just as long as she drinks she will be fine she will eat when she feels better good luck i hope all goes well

In all honesty, I have no clue what could cause a fever for that long and it isnt good that she isnt eating. Make sure that she keeps up on liquids and some foods that will be easy on her. And I would go to the doctors and flip out on them, I mean literally, your daughter shouldnt have a fever for that long and they should do something about it. Best of luck!
