No one needs 500 words to describe kidney stones as one word clearly sums up this malady:OUCH. The pain during a kidney stone attack is enoughto bring a man to his knees and to the ER for a morphine drip. The pain starts in the lower back and travels around to your groin. The wave of pain is beyond description and, G-d forbid, you get an attack, you WILL KNOW IT. There a two types of stones and no one knows why we get them. Keep hydrated and good luck.
