13 year old girl with pain on right side of abdomen has had ct scan in November 2012 which showed only mild hepatomegaly ,, small amt of fluid in the pelvis . Ultrasound two weeks ago found nothing but slightly enlarged liver, small amount of free fluid adjacent to the right ovary, pancreas head was not visualized because of bowel gas. Pain is every day and some days with great severity. Ate a fatty dinner tonight, fast food and is having a lot of pain in the area. What do I do next???
