I was doing some jujitsu two days ago, and took a pretty hard hit on my right side. Feels like broken ribs (I've had plenty..) The pain in very local, right side about one hand (fingers together) down from armpit. Went to doctor today, and got an x-ray. Nothing appears broken, but a large, 7mm kidney stone showed up. Doctor believes the pain in the ribs is actually caused by the stone. I have no other symptoms. Is it likely the stone would cause that pain?
