In the lower thigh/above the back of the knee, the sciatic nerve divides into two nerves, the  tibial and peroneal nerves, which innervate different parts of the lower leg: Peroneal nerves. The peroneal nerves travel laterally (sideways) along the outer part of the knee and down into the upper foot.
Pain is spread from hip joint to ankle and foot. Sciatica pain of entire leg is caused by irritation or pinch of lumbar 3rd, 4th, 5th and sacral S1 nerve. Pain may be caused by irritation or pinch of one or more than one nerve. Pain caused by pinch of third lumbar spinal nerve spreads below knee joint. Abnormality of 4th spinal nerve causes pain over entire leg and spreads up to ankle. Pinch of 5th spinal nerve causes pain of entire leg and spreads in feet and big toes.
