Had severe kidney stones. Came into ER with excruciating pain. They did not have a urologist on call so I had to be transported to UMC after spending five hours at the ER at Summerlin. The ER nurses were very caring, but the PA yelled at me when I complained about all the noise and commotion. I realize now that noise and commotion are the norm in an ER, but I was delirious with pain and vomiting. Instead of trying to calm me down, the PA escalated this into an argument with me and told me that she could unhook my IV and send me out if I didn't like it. Really unprofessional. I have sent a complaint to the CEO. If I get a satisfactory response, I may change my rating.
