Some emergencies that you should try to immediately rule out are acute cholecystitis, ascending cholecystitis , acute viral hepatitis, SBO, acute pancreatitis. Also do not forget that since the base of the lungs can sit near the RUQ, a Pulmonary embolism can cause referred pain to the RUQ. Many women also display atypical chest pain and could be having an MI with referred pain to abdomen.
