My son went through this and thankful I persisted enough that my doctor listened to me. My son had anxiety about school,which he has somewhat out grown. We were sent to Children's Mercy and he they ran tests. He had small ulcers in his belly from the extra acid his anxiety caused and he was extreamly constipated. His intestines were so full they were up to his ribs. So we did diet changes and he was put on an antacid. While we treated these sypmtoms we took him to a child phsycoligist to help him cope with his anxiety. Now he is nine still has a sentive tummy. He cannot handle oranges but the constinat pain is gone. By the way my doctor originally tried to tell me it was just because he did not want to go to school. While that was part his anxiety he was having real health issues. You are her mom and you know her best.
Good Luck,
