Hi. I went through your concern. You have a condition known as symptomatic gall stones (cholelethiasis). And açcording to the report of your ultrasound these are small stones. Your doctor has probably prescribed you capsule ursodeoxycholic acid which is absolutely appropriate. You should start it. It has very small range of side effects like headach, diarrhea, dizziness, nausea/vomiting and dyspepsia. But most of the pt tolerate it very well. This medicine will solubilize the gall stones. You should take it for at least 6 months. But unfortunately if you experience recurrent Right hypochondrium pain, then you have to seriously think about undergoing surgery. As there is a risk of slipping of gall stone in the common bile duct which will cause severe abdominal pain and serious infection known as cholangitis which will require hospital admission, antibiotics and endoscopy (ERCP). I wish good luck to you
