Hello all I am very happy to be able to join this website and learn more about TKD. I have a question that have been bugging me for at least six months. I have this problem which is when I do a high snap kick with my left leg, my right leg's nerve behind the knee tends to be pinched or something. It produces a sharp pain at the knee pit area that is alarming. I am a right handed and legged so I don't have this problem on my left leg when I do a right leg high snap kick. Any advice on why is it like that and also what stretching exercise can I do to make this pinched nerve problem to go away? Thank you very much.
