"Not happy with the report on my arm"

Fell two years ago and went to Queen Elizabeth hospital, for an emergency operation on my elbow next day. Since then I have had three more on the elbow and it’s still not right. I want to know why? The answer you get is, that we just have to take their word for it. But that does not say we have to like it. The last operation was march this year. On being discharged, I told one of the staff there was all blood inside my plaster. I was told, we cannot afford to change plaster, it’s very expensive, go to plaster room in fourteen days time. Upset that I am still in pain, and still cant do much with arm.
