What's the deal w/ itchy zits?

Man, I’ve been getting pimples, or something like pimples, that itch like mad. WTF?

Some horrible arthropod is munching on your face at night!

But really, itching is a form of pain so probably whatever is causing the zits, irritating your skin, is making your itch-receptors go zing.

Well, they tend to stick to my back, and to spots where they are particularly difficult to reach & give a scratch. They’re incredibly annoying—totally adding injury to insult!
