DD has had high temps (up to 40) over one or two days at least three times over the past two years. No other symptoms and it goes up and down with Nurofen or Panadol doses. Every time I've been told 'it's a virus'.
Even when I took her to the ED with the really high temp, they weren't particularly worried and said the same thing. Still, I have always and will always, continue to have her checked. It can be a little worrying huh?
Hope he feels better real soon.
