Could I have Kidney or Gall Stones, I swallowed rocks by accident?

In 2007 by accident I swallowed like 10 really small rocks anyway my question is because I swallowed these rocks by accident do I now have Kidney or Gall Stones because I have a terrible pain in my right shoulder and I want to know is it a result of possibly having Kidney or Gall Stones now? The pain didn't start until April 2009 so is it possible that I just crapped out all the rocks I swallowed by accident how can I get tested to see if it is indeed the rocks that I swallowed that are stuck somewhere in my body causing me the shoulder pain?
