Pyriformis v disc: This sounds like sciatica(pain over this large leg nerve's distribution to the foot from the buttock) which can occur due to a disc herniation in the lower back compressing a spinal nerve and not cause any back pain or be due to a hip muscle known as the pyriformis irritating the sciatic nerve which it straddles in the buttock region mimicking a disc herniation pattern.
