The femoral nerve is the major nerve that serves the tissues of the thigh and leg, including the muscles and skin. While the much larger sciatic nerve also passes through the thigh on its way to the lower leg and foot, only the femoral nerve innervates the tissues of the thigh.
The sciatic nerve supplies sensation to almost all major muscle groups in the lower leg. The femoral nerve supplies sensation to the muscles in the front of the thigh down to the knee. Irritation or trauma to these nerves could produce hip pain that travels down the leg.
