Hey guys, Ive never posted here but was hoping you could give me some insight.
One of my boys developed a rash behind his knees. Tonight it really flared up. Down his arms, all over his face. Would a food allergy rash take multiple days to develop? It's red and round and splotchy, but not raised and it doesn't appear to be bothering him.
Any advice would be appreciated
