LOs face is so red

As

Only his face gets so red and blotchy and it just started 3 days ago or at least it started getting worse 3 days ago. He would get redness around his mouth from teething, but now it's his whole face. No other symptoms, his normal self but his body will get very warm, no fever though. The redness will come and then a few hours it will pretty much clear and then come back.

We will see the pediatrician, but until than any ideas?
