I never even owned a thermometer until, now adult, DS1 bought on when his GF was ill. I used to judge how ill people were by feeling their forehead and watching their behaviour.
Anyway, GF is lovely, but often ill and seems (compared to my normal) to consult a doctor a lot for things I'd wait for. But is it me?
So, she has a temperature of 39 point something, according to DS's thermometer. She's clearly not well but she's awake, drinking, breathing OK, chatting. Personally I wouldn't call the doctor (111) but DS is very worried and wants to.
Would you? Obviously she's an adult and will make the decision herself, just interested in opinions. Apparently NHS website says you should seek advice from GP for any temperature over 39 in an adult, but in my (old) world I wouldn't have known exactly how hot they were and wouldn't have worried unless they were very listless or not drinking.
