Yes....Sounds to me like sciatic nerve is irritated.
Per the above article:
The piriformis is a short, very strong muscle that lies at the back of the hip joint, going from the top of the femur (thigh bone) across the hip to the pelvis. Immediately beneath it and between the muscle body and the bone, lies the sciatic nerve and all its branches
Also in the article... radiating pain down the sciatic pathways, commonly called sciatica, which travels down the outer side of the leg, often as far as the ankle and foot.
