"Not enough help for severe pain after knee replacement"

In March 2006 I had a complete Right knee replacement.which at first appeared to be in order, In December 2006 I started getting severe pain in the knee, I made a special arrangement to see the surgen but when I attended hospital I got an underling, He did not examin the knee but just said he would make arrangements for me to see a Physio,

I have been attending the Phisio for 8 weeks and he has just sacked me saying I can bend the knee and strighten the knee and ther is nothing else he can do, I could always bend and strighten the knee,

But it is the severe pain that is causing me to loose my sleep that I find hard to bear, but no-one appears to give a damn
