What could this pain if the gallbladder has been ruled out?

Don't know: It depends on the characteristics of your pain - onset, duration, location, radiation, aggravating and alleviating factors, and severity to name a few. Gallbladders can also cause pain without stones. Ask your doctor if a CCK-HIDA scan would be appropriate. I'm not saying that's what you need, just trying to give potentially helpful info.

More info needed: Describe your pain, location, movement of the pain to somewhere else, quality and severity of pain, what provokes it, what relieves it, when does occur and how long does it last. Gallbladder pain is usually in the right upper abdomen and is pretty consistently brought on by eating a fatty meal, may last up to 24 hours.
