"Nurses do not do their jobs properly"

I have just been to the orthopaedic unit and can honestly say that I am appalled at the service. Some of the nurses do not do their jobs properly; as soon as I came into the ward all I could hear was my close family member screaming and crying in pain. I know that this was heard by every single member of the staff but they chose to ignore him. My family member needed painkillers and we were ignored multiple times. Eventually, after continuously going to the nurses, asking for their help, they listened and gave the painkillers. I honestly think that they do not know the severity of how painful it is after a person comes out of surgery. There was a student nurse who was helping us a lot and I'm ever so grateful, I also went to the nurses to ask for something for my family member to vomit in and was told that visiting hours have finished and I had to leave. What has that got to do with anything? He needed to vomit and I'm asking for help and received nothing but attitude from the staff even though I was extremely polite.
