this afternoon about 4ish my ds (8) was playing his computer in his room, i went to check on him and he was in bed crying he said he felt sick and had a really bad headache across his forehead, he was also very hot all over, he stillc ame down and ate some meat balls though, i gave him mediced and ibuprofen and sent him to bed in the dark, checked on him 20 mins later and he was a bit more chatty, since then he's been acting perfectly normal, my question is, can a one off headache cause a temp?
