Can kidney stones feel like gas pains?

I have had pain all day in the mid-to-lower right side of my abdomen. It started as more of a dull annoyance, but seems to be a bit worse now. I have been researching kidney stones, and the location of pain seems to match, but not the type of pain. It is not excruciating, but seems to sharpen when I move around. It almost feels like gas pains, but not quite the same. I have no other symptoms. Can anyone offer more insight as to what this might be?
