Shingles

If you just got shingles, it's not smart to poke the blistering, oozing rash to test how much pain you can endure before you scream. On the second poke you will be hopping around shouting, swearing and cursing, and you will be spitting everywhere. Not to mention you will also hit the rash AGAIN on the corner of the kitchen counter, and you will repeat the cycle of screaming, rolling, and hopping around while your neighbor is staring open-mouthed at you from across the street through his window.
