My ds fires up with temps of 40 during the night which I give him calpol/ibuprofen for and they last for instance from 6pm until 6am and then is fine again for a couple of days. The high temps are nearly always during the night and he gets really very hot! This has been going on for a good few weeks and it is not ears, chest infections etc. Doctors just say virus but does anyone know if it can be anything less obvious and more worrying?
