<s>[INST] I have had very bad pain under my rib cage, that rotates from left to right and sometimes hurts both sides at once. Also I have been feeling a lot of pain in my flank area on the right side. I have been to the er and the doctors several times or this and tests have showed nothing. I have had x rays ct scan and ultra sounds. Although. very relieved that test show nothing I am in an awful amount of pain and still very concerned about my health. Any ideas [/INST] HelloConsult your doctor for doing an abdominal ultrasound for evaluating the liver and intestines.RegardsDr.Jolanda </s>
