22 yo f in good health experiencing mild pains on right lower rib cage. pain in right back when running. kidney disease or liver cancer likely?

Q 4 Physiatry, Sport: A healthy runner would be unlikely to have a major illness. Hence if i saw someone in my college town practice who was 22, i would refer her to orthopedic surgery or sports medicine clinic for initial evaluation. I would not drop things there, however. I would communicate with all of the consultants, look at ehrs, speak with the patient about changes and continue to refer to specialists as needed.
