My daughter is 12 and has been suffering with what the gastro doctor calls IBS (only with constipation) for the past 2 years. She goes through bouts of severe abdominal pain which always goes undiagnosed at the hospitals. The doctors always send her to the ER for possible appendicitis. It never is. Well now she is suffering abdominal pain in her lower right side of her abdomen and in her back in same general area. It hurts to stand, cough, lift her arms, bend over and the pain is constant over the past two days. She feels it is getting worse. However, she is still eating and has no fever (two symptoms the doctors at the ER said she would have are fever and loss of appetite as well as pain so bad she can t sleep). She slept last night although she said she woke a few times but went back to sleep. My question is, should I take her to the ER again or wait to see if she gets a fever? I never get answers at the doctors or hospital as to diagnosis, so I only know what it has NOT been in the past, and she has never had appendicitis.
