Just the back of my left thigh goes numb when i sleep in certain positions with my leg bent. goes away when i straighten out leg. nerve issue?

Yes, Nerve Problem: In the back of the knee joint, there is a depressed area called popliteal fossa. The sciatic nerve becomes tibial nerve in the popliteal fossa. It seems that the popliteal fossa is getting compressed b/c of sleeping with your legs bent. This is compressing the sciatic and tibial nerves, resulting in numbness of the back of your thigh.Thanks.
