Don't worry Devil it will all work out in the end. My mother has had 2 full knee replacements. She had one and then a few months later she had the other. She doesn't regret it at all...(plays 18 holes of golf a day) Her advise is never stop or quit doing the physio untill its done. It will be painfull but its worth it she says. The Only people she has met that regretted getting it done are people who gave up on physio...So good luck my prayers are with you. And remember anything worth having is worth working for.
