I am a 43 year old female. I have had nausea, heartburn, bloating immediately after eating. Dr. said it was IBS but symptoms wouldn't go away. She gave me an ultrasound and it showed 1.3 cm polyp on gallbladder. She said I was fine and will do nothing. Now I am getting pain under right rib cage. I've heard I should have polyp/gallbladder removed for that size. Should I get a second opinion?
