Hi and welcome to HCM.
This sounds like
biliary colic, but also there can be asociated panceratitis or hepatic distension pain. i dont consider this is an emergency, but you should consider
cholecystectomy as soon as possible.These stones can cause intensive pain,
cholecystitis or pancreatits so be aware of it. If you notice dark urine,
jaundice, pain in the back fever and vomiting you should go to ER. WIsh you good health.
