In brief: 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.

Neurology
In brief: A pinched nerve
A pinched nerve or compressed nerve root (sciatica) can cause pain in the buttock going down the leg in the distribution of the nerve which is compressed.
The most common causes of pinched nerves are herniated discs and bony spurs.
