Popliteal fossa: The area behind the knee is called the popliteal fossa and the nerve supplying the foot (sciatic) is right there. Sometimes people develop a cyst in the knee that can protrude in the back of the knee and compress the sciatic nerve branches. You should get evaluated by an orthopedic surgeon who can get an MRI and advise. The nerve symptoms deserve prompt attention. Good luck

Knee pain: I agree with Dr. Patel. You should have him evaluated. Since he likely won't need surgery before other conservative treatments are used, it would also be fine to start with an evaluation by your Family Physician.
