Chicken pox?

The doc thinks Johnathan has chicken pox. They are an atypical presentation, though, so we can't be sure. They have developed a bit oddly in that they developed on his groin area first, then moved upward rather than vice versa. I'm not convinced it's chicken pox. I guess the way to tell will be whether he continues to break out. I'm supposed to call the doc back on Monday to report what has occurred over the weekend. He doesn't have a fever and the papules don't seem to be bothering him. Odd.
