hi, my daughter is almost sixteen and has been complaining of pain in her lower left abdomen. we went to the doctor and they said it would go away but it has still been there and it's been almost three weeks. i was wondering if anyone else has ever experienced this. she says it a sharp pain in her lower left abdomen and it intesnifies whenever she excercies. she runs xc so was hoping to get a good summer base in but has been practically unable to run at all because she says it hurts so much. any solutions to help or ideas of what i could be would be greatly appreciated. thank you for your help!
