Go in and tell them you are having a pain in your right side right under the ribs that is dull and pretty much constant and you wondered if it was GB or something else. Should work. I had no gall stones visible. so at that time I think they said it was colon or stress or whatever. I don;t remember. But keep in mind Hanna or someone said you don;t see choloestral stones spelling??? just Ca stones. So I can assume I have the former... but I have them...
