60yoM presents with Intermittent RUQ pain x 2 weeks. Currently in no pain. States that pain will come on randomly and suddenly. Lasts a several hours. He is a Retired Master Gunnery Sergeant and doesn't believe in complaining, so he has not visited an ED. Notes that the pain has decreased his appetite and will cause him to be nauseous but only occasionally vomit. He is otherwise healthy and takes no medication.
