chockie,
It seems that these days, when children get viral infection, they wld hv fever for a week or more. The fever tends to come n go, temp goes up often in the nite. My kids went thru it a few times. The 1st time, we were like u, got so worried n kept visiting the doctors. The last straw was we went to Thomson Medical 24HR clinic. Cos we so worried, they took blood test to confirm its viral infection. The experienced nurse told us to feed the kid panadol diligently every 4hrs for 2 consecutive days. She said to do it even thru the nite or there is no fever. We followed her advice & it worked! 3rd day onwards, the kid fully recovered. From that time onwards, we always practise that and it worked, the kids usually recovered aft 2-3 days.
My older girl, when she gets fever, she will hv goose pimples every now n then, esp when there is change of temp, like from the hot weather outside to inside aircon place. She also tends to hv cold hands & feet.
Oh, when my kids' temp goes to 40deg, when we were at Thomson Medical, they quickly inserted repository. They gave us some repository just in case the temp goes up at home, but important thing is dun use it if u hv just fed them neurofen. U got to wait at least 4hrs I think. So far, I tried not to use repository n neurofen, I just give them panadol regularly n sponge them.
Oh, 1 more thing... these days, kids also tend to have rashes after viral infection. My little one had rashes after 1 week of fever, I got so worried n went to see GP. He just said, "Oh, that is a sign that she is recovering." No medication was given to her. I consulted a doctor friend and he said yes, it can be the case.
Having shared our experience, then again, not all cases may be the same, so if condition does not improve, please do go to the doctors.
