Mystery spots cause family panic

Last week, Daniel developed a little spot on his shoulder. I looks like the dry skin spots I get in the winter, and I've been treating it as such. But Friday night, I developed what I thought were hives on my palms. So I changed the lotion I've been trating him with. Well, the "hives" haven't disappeared, and neither has Daniel's little spot. So now I'm afraid mine might be something worse, and since I've been smearing my hands all over his little shoulder it's a sure bet he'll have it too! Aaak!
Heigh ho, heigh ho, it's off to the doctor we go...
