"Poor communication and disjointed service"

Having visited the Urgent Care A&E at Croydon University hospital, I have some real concerns relating to the quality of patient care. I visited as I had fallen and was in a lot if pain and was worried I had broken my arm. I was initially seen by a nurse who was rather cold and sullen. After looking at my arm, she walked me to a doctor who glanced at me and sent me to get an X ray. I then waited in reception for around an hour to be called in by a different doctor, who did not know I had been seen and did not know I had already had an X ray - and seemed very surprised when I told him. To my knowledge, he did not look at the X ray results. He then felt the bone in my arm and told me it was broken but not too badly. He gave me a sling, told me to ice the joint and take paracetamol and try to move my arm when the pain lessens. As I was in a lot of pain, I wasn't in the right frame of mind to ask more questions and I was sent out. I have no idea which bone is broken, what sort of break it is, how long I can expect it to take to recover, how I am supposed to manage quite extreme pain or how I can work when I can't use my arm or why a cast wasn't considered. I am still in pain and I have no information other than that my arm is broken and the doctor hadn't looked at my X rays ( nor was even aware I had these done). All round, this has been a confusing and poor experience and I am now unsure as to how to resolve this.
