According to an old fairy tale, a single tiny pea placed beneath 20 mattresses and 20 featherbeds was enough to keep the true princess awake throughout the night. In real life, a tiny pea-sized stone, lodged in the ureter, is enough to keep you not only awake all night buy crying out in pain and gritting your teeth until you can get to a doctor for relief...happy I'm married to one.
I would much rather deliver a 9lb 5oz baby (which I have) then deliver 3mm kidney stone......
That is all I have to say about that!
