Shamelessly posting for traffic sorry.
I was asked to pick my son up from nursery this afternoon as he had developed a rash and been sick.
There was absolutely nothing on him when I dropped him off at around 9am, he was his usual self, and nursery said they didn't see it starting until later on in the morning they rang me at 12 at which point it was just starting up his back but he'd also been sick. In the space of a few hours he now has a rash like this on his back, all the way up his arms and legs (not much on his front so far though).
He does have rashes when he has viral infections but not seen one develop this quickly before and they always seem more pin prickly if that makes sense? Whereas this seems a bit more bunched together/bigger spots.
It is blanching and he still seems okay in himself and hasn't been sick since. Hold off calling the doctor?
