Red cheeks, not teething, what is it?

[goandshowdaddy]

Hi,

DS2 (2.4) has been pretty miserable the last few days/week and keeps coming
up with bright red cheek/cheeks (sometimes one, sometimes both). He's got all his baby teeth so definitely not still teething. What else could it be? I wondered about slapped cheek but it seems to come and go so not sure?

Oh and DS1 has chicken pox - could it be related?

Any ideas?

Slapped Cheek most likely , Scarlet fever (sore throat?), a.n.other virus

OK, thanks.

He keeps pointing at his mouth and saying he's hurt himself but won't let me look - think he might have bitten the inside of his cheek though so that's just probably something else!

If Slapped Cheek, do I need to do anything/get any medicine/keep him isolated or just let it run its course?
