Girls, hello everyone, help with advice ? We all got sick, I have a fever of 38, my husband has 37, the little one held on for two days, and today it rose to 38.6, knocked down with Nurofen to 37.5, the question is in what. What else can you lower the temperature? (candles cyficon can be given once a day, I put it and it showed through 1-2 minutes, they told me to give Nurlfen) Is it worth lowering 37.5?
