Update

Well, DS is home. The emergency room couldn't really find anything wrong with him, and he seems to be okay now. He is going to have a follow up visit with a pediatric cardiologist.

I was checking out the paperwork from the hospital, and saw that it said a foreign body was removed. Huh? What the heck kind of foreign body? So I went and asked DH. He said "Oh, they pulled a green thing out of his ear." A green thing. Well, now we know why he had an earache a couple of weekends ago. Sigh.
