Pain in the fight leg

Patient: I am having pain in the right leg when I sit cross legged. It starts after about 5 minutes and then increases steadily. It becomes unbearable and then I have to get up or stretch my legs. I find it extremely difficult to get up and there is a lot of pain which lasts for a few minutes and then subsides. It has been like this for the last few months.The pain is like an electric current starting from the hip to the foot.
