Sudden and rapidly intensifying pain in the upper right portion of your abdomen
Sudden and rapidly intensifying pain in the center of your abdomen, just below your breastbone
Back pain between your shoulder blades
Pain in your right shoulder
Nausea or vomiting
 Gallstone pain may last several minutes to a few hours.
