Knee replacements 18 months ago. For 18 months i am still in excruciating pain. Can barely walk. Cant do stairs and cannot even stand in a queue without feeling I'm going to collapse. Even the inane act of stepping down a kerb is agony! I can't cope with this anymore. Been back to the hospital many times only to be told to go to a pain clinic. No answers as to why. I am allergic to nickel however two consultants I've seen have reassured me that it won't be that. But no idea what it is. I'm getting to the stage where I would rather have no legs than best this pain anymore. Is there anyone out there that is still in agony after tkr????
