"Not given pain relief at the specified times"

Left on a trolley in a corridor in absolute agony for over an hour with no pain relief or gas and air. Nurses could clearly hear her but ignored her. In the finish I had to raise my voice to get their attention and they ended up getting security in say I had threatened them of which I did not. When she got on the ward 5 hours later the nurses in the night were perfect, however there were problems with the day staff that treated my wife. Refusing to give pain relief at the specific time they were told to and made her wait in agony for 45 minutes. Unacceptable behaviour. They also were very rude and in my opinion completely unprofessional.
