<s>[INST] My 15 year old daughters stomach makes popping noises. Like when a joint pops. It first happened a year ago and stopped. It has started again (about a week ago). It happens several times a day and is painful. I have taken her to an er doctor and a pt who both have no answers. She is a soccer player and it is painful [/INST] Hi...by what you quote this could be chronic pain abdomen. Most of the time we do not find a reason for it even after extensive investigations. I have a few questions and suggestions for you - Questions-1. How many months is she having the problem?2. Is there any family history of gall or kidney stones?3. Did she have urinary tract infection in the past?4. Anybody else in the family is having a similar problem?5. Does she have constipation? Hope my answer was helpful for you. Get back to me with the above answers. I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health. </s>
