You where correct in that it is the knee LCL that is the primary injury. However secondary too it I have been having pain in my foot as well, however like i said it is thought this may just be because i have had to rest due to the knee injury. I have begun trying to walk about as much as i can without crutches but it feels a little odd.

I have some basic exercises for the knee such as bending and straightening...

Sorry for any confusion and thanks for your help!
