Hi, I am a keen runner and have run a few marathons, the last one a couple of years ago. I have just found out that my recent injury problems are due to arthritis in my knee and hip and I am likely to be needing a hip replacement before too long. Does this mean the end to any running? Does anyone have any experience of this? I know there are some out there that will think I should be grateful I can even think about running, but I am still angry that my body seems to be letting me down and stopping me from doing the things I love. Any info welcome.
