Thanks everybody for the replies.

I have tried traction on a traction unit on this guy as well as tib-fib mobs along with deep tissue release on the peroneals. But unfortunately, he is still the same and I am not sure what can I do further for him.

He is waiting for an Wikipedia reference-linkMRI scan for the problem.

As I mentined earlier his only problem is the numbness in his foot rather than pain.
