Not too worry. Both my kids had the same thing. The older one started at 4, and younger one earlier than that. They complained about similar positions (thigh above knee) and I remember only one leg. The older one grew out of it after 5, and younger one still on going. I noticed that if she sat there in one position for a long time, the pain gets worse. Must be circulation related. I was scared many times, and I went through their legs, feet little by little - nothing seems to be out of order, except the pressure just above the knee.
