It's hard to say for sure and I'll admit people do things wrong. But even if just the manner of how nursing staff treat you is off its ok and right to complain. Hope its healing up ok and your keeping safe.
Reeta, Sorry didn't want to make anyone feel old or out of date, it may be a field I don't get back to but its handy to share info, different places do things differently so its good to get a broad opinion.
