My mother was in so much pain from arthritis in her knee that she was admitted to hospital.

Doctor said there wasn't much they could do apart from managing the pain. My sister pressed back, saying there must be something he could do.

He said that cortisteroid injection in the knee was an option, but there could be long term complications.

Mum, "I'm 90, I don't have a long term!"

She got the injection and it worked.

She was also right, she only had another four years - but they were pain free years.
