My daughter has been having pain in her right lower abdomen. It comes and goes. Today the school nurse called me to pick her up because of it. The nurse says she has rebound pain in that spot in her stomach. We just got home and she is just fine. I was wondering if I should get her checked out for appendicitis or wait to see if it gets worse?

You don't wait till it gets worse, why would you do that? Take her in have it diagnosed properly.
