Thanks for your reply's
I'm only 21, so I hoping I'm not aging too quickly otherwise I'll have to start planning my funeral now :-)
I did a web search and I guess I have subluxating peroneal tendons... go figure. Which isn't too serious.
I'm currently training in Aus... and just making sure in the future, I'm going to have sufficient ankle function left to kick enough rudder in a wing drop :-)
