Hello, my son has had high temperature of 39-40c for about 5 days, he s had sore throat , cough etc. Thefever only comes down after ibuprofen . When his temperature is normal he is fine, he eats and drinks plenty and plays, and is generally well. Last night though he went to sleep and his temperature was 37.2c. When I checked him after a while he had been sweating a lot and he was freezing under the covers. His temp was 35c. I covered him more, but this made him sweat more and his temp didn t go up to normal. Now he is awake he had a temp of 38.8. I will be taking him to the doctors tomorrow, but the low body temp has scared me
