I went to the ultrasound waiting area right away was then told to go up to ER to check in because it was after hours and not sure if they needed more info from me. The girl there was nice and all but very confused as to why I was in no pain and needing an ultrasound for my kidney! Long story short she thought I was there for ER and that the ER was the ones telling me I needed an ultrasound when it was my primary Dr requesting it!!
