7yo has had a cough for 3 weeks, took his temperature on Sunday and it was 39 so kept him off school in Monday, Tuesday he seemed quite unwell, pale and tired, so took him to the doctor who said it's a bronchial infection and proscribed a 3 day course of antibiotics (though Google sugfests 90% of bronchial infections are viral so maybe unsurprising this hasn't helped) and said to keep him off til Friday.
He's not unusually tired any more, probably because hes just been at home not doing anything, but his cough is unchanged and more worryingly temperature remains at 37.8 first thing in the morning. Since Sunday its only been lower with meds, as soon as Calpol or neurofen is out of his system it goes back to 38 or 37.8 or 9. He didn't want any fever medicine yesterday and his temperature just stayed around 38.
He's not listless, that was just on Monday, he is awake all day and playing.
Is his temperature a worry, is it normal that it just isn't going back to normal? The cough is unchanged too.
Is there anything I can do?
