lithotripsy
"Lithotripsy is like getting jabbed in the back with an unsharpened pencil once per second for an hour. You'll be bruised and a little sore. You also might have fragments that didn't get fully fractured that can pass, but will take time (and pain) to do so."
"Lithotripsy is like being slapped with a 12-inch ruler but works a treat if the stone is in the right place. "
"Compared to the pain pre-stint, lithotripsy is like eating ice cream. No pain AT ALL!!!! Haven't taken a single pain pill since."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
