hi. noted history of right sided abdominal pain radiating to the shoulder area. it is possible that you have a gallstone disease. it is best if you consult with a doctor, preferably a gastroenterologist or a general surgeon, for physical examination and clinical evaluation. diagnostics (such as ultrasound, liver function tests, alkaline phosphatase, blood count, etc) and management (medical and/or surgical if indications are found) will be directed accordingly. if it is indeed a gallstone disease, definitive management is cholecystectomy (surgical removal of the gallbladder) which can be done laparoscopically (goldstandard) or thru open technique. low fat low salt diet is also recommended. hope this helps. good day!! ~dr.kaye
