My 12 year old daughter is very active in a variety of sports-soccer, basketball, dance, baton and when she runs hard she gets a sharp pain in her left side. I keep telling her its just from running and to stay hydrated, lots of water but should I bring her in to the doctor? My daughter is constantly wanting to go to the doctor and thats my concern, is she just crying wolf again? Most times when I do bring her in, its nothing...Thanks, Concerned Mom
