My 2 year old son has eczema. He has had it pretty much since he was born, nothing out of the ordinary, I know what to do for it. But he developed a patch of eczema that's kind of worrying me. Its on his leg right where his butt and his leg meet, and it's a large patch, picture the size of a chips ahoy cookie. What worries me about this one is he has five or six red raised bumps inside of the patch of eczema. He has never had that happen before. Any ideas on what it could be?
