Gall bladder has been hurting all day. Felt it spasming earlier. Now just a dull pain. Could it have ruptured?

Gall bladder pain. Gall bladder pain might be due to infection/inflammation, obstruction of the bile duct(by stone for example) or rupture. if you are having fever, severe abdominal pain and rigidity of your abdomen please head to the nearest ER.
Not yet. A "ruptured" gall bladder would cause significant pain and other side effects. Could be just spasm or a stone. The symptoms are significant enough to get to see your primary care physician very soon.
