Training around an injury?

Hi all,

I used to train in ITF TKD for a number of years, but sadly had to stop after sustaining a hip flexor injury which 13 years on still seizes up and gets uncomfortable.



I really would like to get back to training again, especially since there's a class 6mins drive from my door.



Any advice on how to train around an injury? Or should I just not bother with TKD and try a different art? There's a pretty good Wing Chun school nearby...
