It's pretty bad Tony and makes day to day tasks a chore, but it ain't gunna kill me thankfully.
Taking 40mg of Zomorph (slow release Morphine) twice a day which helps a little but it's not an ideal solution. I'm hoping once my knee is sorted I can come off it. It's not something I want to be taking long term.
I get to spend every day at home with my kids though which is a bonus as I had to pack work in, in June 2013.
