unhappy with answer
It was a knee replacement. The injury was due to a doctor trying to check the condition of the knee and the capsule was ruptured. A physiotherapist told me that it would heal itself over time but it hasn't done. There is now a fluid sac under the skin at the side of the knee.
I have been told that to use a needle to draw the fluid off would be too risky for infection?
OK thanks. I will go back to the surgeon who advised me of the risk of infection and said that I would probably need another replacement knee.
