Since then I have lost confidence doing certain movements for fear of making the injury worse.

It has also caused a change of focus. for the last three weeks all I have been worried about is how to get the ankle right. I haven't been thinking about how I can win the world title.

So the emphasis is taken off the squash for a while, which, as it happens, isn't necessarily a bad thing.

The most frustrating thing about this injury is the uncertainty.

It isn't like having a broken leg where the diagnosis and treatment are clear cut. It has been very much a matter of seeing how it responds to treatment day to day.

I get my hopes up, becoming excited about the fact that I might be able to play again, only to be told by my physio to lay off for just a bit longer.

What's he moaning about, I hear you ask? Must be great to have a bit of time off.

Believe me, I would take the most painful of all training sessions 20 times over rather than be injured – any day.

But who am I to complain? I've only been injured for three weeks and even then I haven't had to stop completely.

Nick Matthew, an England team-mate, has just had eight months off and Anthony Ricketts, the former British Open champion from Australia, had his career cut short at 28 through injury recently.

David Campion, now a national coach and someone who had a massive influence on me, hardly got started on what looked like a very promising professional career due to injury.

Fifteen years ago, when David was starting out, the knowledge about rehabilitation and the importance of physio and strength programmes just wasn't available.

He knows much more now, but it's unfortunately a little late for him, although not too late that he couldn't win the British Open over-35 Championships this year – a tremendous achievement.

It's a good thing for today's athletes that injury prevention and treatment has come so far.

The science is a great help, but there's always another ingredient that is needed...and that is luck.
