SAN FRANCISCO -- Rich Aurilia knew immediately what ailed him when he was driving through Scottsdale, Ariz., on Thursday morning.
"It felt like somebody stuck a knife in my rib cage," Aurilia said Friday, one day after a kidney stone knocked the infielder out of the Giants lineup.
Although Aurilia, 36, had never endured a kidney stone, he had been told about the misery they cause. The diagnosis he received upon rushing to a local hospital confirmed what he sensed.
As of late Friday afternoon, Aurilia hadn't yet passed the stone. However, he was able to shake the overwhelming nausea enough to resume eating. All he could do was follow medical instructions and wait for nature to take its course.
"Today I feel a little better, but I'm still in pain," Aurilia said.
