My child does suffer from headaches which have now been diagnosed as occuring because of low muscle tone & scoliosis. Her headaches have gotten better however over the last two days she has been complaining of severe headaches, tiredness and now she has a temprature of 37.5 degrees orally. It is very cold here at the moment & she has been complaining of freezing when the rest of the family is dressed warmly & are only mildly cold. Do I need to panic or could she just have slept funny (she had a very sore neck this morning when she tried to turn it) & that could be causing the headaches? Not quite sure what about the slightly elevated temp though?
