I am losing it

We get through one traumatic event and then another one follows. My daughter has been diagnosed with hip dysplasia. I had it as a baby and I told the doctors this and trusted that they would continue to look for it. Why did it take them a year to discover it? If I wouldnt have told them about the weird thing she does when she tries to get on all fours they wouldnt have even looked into it. I AM NOT THE DOCTOR. I am changing pediatricians as soon as this treatment is over. It's just ridiculous how much my child has gone through needlessly. It is hard for me to describe how angry I am. I guess that is what happens in the age of "cattle call" doctor's visits.
